Mark. That’s so kind of you to take the time to watch and comment. I really appreciate it. When I was researching I saw some pretty wonky stuff out there. Please feel free to share (I don’t know how you do that). Cheers.
I have been trying to understand that insulation and vapor barrier logic. I watched tons of videos. Almoast every single one of them confused me a little more. Untill now. This old school fella vleared my mind. I genuinly thank you for making this video simple and effective. I thank you from the bottom of my heart
Youi guys rock !! I love this product and feel very comfortable recommendng it. Now that we've been on the road several times I can't beloeve how quiet the ride is too. Be well
I just wanted to commend you on your replies to some of the comments that seem quite critical of your method of insulation. This seems to be almost an emotional subject to some. Personally for myself in my '20 Promaster Im using thinsulate on the large flat surfaces, leaving the large cavities at the roofline sides and down the ribs along the sides open and free as an air passage way though all ribs are covered on the living side surface with 1" R Max. All four corners at the ceiling have 4" computer fans built in drawing air after a humidity event from the floor area through the ribs of the van into the living space and expelled by the 2 Max Airs vent on the roof. Absolutely no inner vapor barrier for me as the outer sheet metal of the van is a given vapor barrier and I dont want to trap moisture between two vapor barriers.
Hi JG-k4oi - thanks so much for watching and taking the time to comment - I believe it's in the conversation we learn and grow. I don't have to be right. - yes - insulation sure gets the blood going. So many different ways to it. I'm intrigued with your use of the fans. I agree with the concept but I'm not certain of the effectiveness in extreme colds. The difference in temperatures outside / inside and the small R value of any insulation is going to cause condensation - maybe not where the air is moving - but at the dew point of the system everywhere else. But that's just me ... let me know how it works. I hope you'll join the community and stop back. ..... Dave
@ 2:42 You almost got this right here, but you omitted the now-standard Tyvek housewrap (barrier) that effectively prevents moisture infiltration from the outside of any modern residential construction. @ 3:19 "...but in a van, the outside layer is the vapor barrier.. ...we're almost turning our [conventional building] system inside out..." In a metal building (or a van) you have barriers on *both* sides, preferably with impermeable thermal resistive insulation (i.e.: has an R-Value) in btween.
Hi Video Pipeline - thank you so much for watching the video and taking the time to make such a detailed comment. I love these - I believe that it's in the conversation that people learn and form their ideas. I know there are a ton of people lurking here. And my experience in van building is that there can be tremendous differences between the theoretical building concepts and how things actually work ...... * Yes* - I did omit the Tyvek housewrap - which is a very effective moisture barrier for air coming into a house. However, I disagree with the comment that " ..... In a metal building (or a van) you have barriers on both sides,...." you'll only have 2 barriers if you build in 2 barriers and I don't believe it's possible to do that on the inside of a van without using a closed cell spray foam. A product that would totally change the build. In my opinion it would not be practical to try to create a wall cavity that was completely sealed on both sides. And even if it was possible, given the small amount of insulation in that cavity all you would accomplish for the effort is a moving of the dew point - because there's gonna be one. The question is where is it best managed. For my van , where and how I use it I'm happy with the results. ..... Be well and I hope you'll stop back ..... Dave
@@VanOfAction re: "I did omit the Tyvek housewrap - which is a very effective moisture barrier for air coming into a house." As you probably know, the benefit of Tyvek (and subsequent comparable products) is reduced wind infiltration and bi-directional vapor permeability, so if resists wind pressure driven moisture laden air from entering the wall cavity, but more readily permits moisture to escape from the wall cavity. This is almost exactly the opposite of how wool performs when used as bulk insulation in a wall cavity (metal buildiong or van makes no difference). "In my opinion it would not be practical to try to create a wall cavity that was completely sealed on both sides." Herrmetically sealed is not typically possible, but sealed to the typical vapor pressures encountered certainly is, and in fact new buildings in coastal areas are typically built to this standard. Some people don't want to seal off the inside surface of a vehicle skin due to concerns about making collision damage repair more difficult. To each their own, I guess, but IMO that's a strange prioritization. "And even if it was possible, given the small amount of insulation in that cavity all you would accomplish for the effort is a moving of the dew point - because there's gonna be one." In cold exterior temperatures, the dew point will be on the outside. The primary rationale for using thermal insulation is to allow living spaces to be conditioned, in which case there will be no condensation on the inside walls even when the space is relatively full of breathing occupants.
Hi Video Pipeline - thanks for taking the time to respond. You clearly have a concrete grasp on the theory of building envelopes. I don't expect you've ever built or spent time in a van. If you ever do you will be able to insulate any way you want, I'm very happy with the method I used and would recommend it to anyone...... Dave
Thank you for sharing...I appreciate having access to honest hindsight before I get started. I am allergic to wool so that mandates a different product... pretty sure i will be using the thinsulate... but putting it in after structure is good math lol
Hi Jess - yep, I wish I had waited - it seemed like the first thing to do but then you fight with it every day. I'm sure you'll find a systemt that works but be aware of condensation .... be well
Jess thanks for bringing up the allergy. I didn't even think of that since I don't wear wool. I have a lot of allergies and will have to look into that.
Hi David. Thanks for watching and commenting. I did not. All in we’re talking about 2 maybe 2 1\2 inches of insulation. I believe it’s possible to over analyze things. I just strapped the ceiling to accommodate the wood ceiling and filled whatever void was created. I hope you’ll stop back and join the community. …… Dave
Hi Deep South New Zealand - IT IS !!!! And I believe that the company imports your wool to the US because it's one of the most reliable in the world - thanks for watching and commenting. Dave
Hi Rachel - thanks for watching and commenting. There are a million different opinions about vapour barriers. Mine is, as described in the video, that the band vapour barrier is on the inside of the body metal. Even if you could actually make a uniform seal on the inside I would not recommend it. Good luck and thanks for joining the community. Dave
@5:23 "Wool is hydroscopic..." which is one of the main reasons *wool should not be used to insulate a camper van* that's not in a very dry climate. Two other reasons: high cost per unit R-value & relatively low R-Value per unit thicknesss. Wool makes a great blanket or sweater, but it's a poor choice for thermal insulation in a structure (or RV) exposed to RH above 50%. To better understand why, refer to these two tests that done by Gary @ Build a Green RV: "Water absorption for various insulation types" & "Insulation Testing - For Van Conversions" Key excerpts: Bare Plexiglass panel showing considerable condensation and beginning to drain down. Wool showing significant condensation, felt damp to touch on outer surface, (+36 g of water pickup). Thinsulate showing significant condensation, (+11 g of water pickup). Polyiso showing no condensation. Polyiso felt dry, (+0 g of water pickup)
Hi Video Pipeline - again, thanks for watching and taking the time to comment. Insulation is one of the topics of a van build that I think will be a never ending debate - this will probably be a long answer, I think it's important but I can't do another video about it right now. In this case, because of what I consider the insulation is for - I disagree with just about everything you've said. I am in Canada, the interior of British Columbia. I don't use my van in the dead of winter but I do use in during the shoulder months when night time temperatures will dip to below freezing. Having said that - there is not a product on the market that will insulate the walls, ceiling and floor of a van with enough R-value to enable the interior to hold heat well enough to maintain a consistent temperature if it's cold outside. If you want the inside to stay warm you have 2 choices. 1. build everything thick enough to hold enough insulation or 2. have to have a constant heat source. Number 1 would accomplish the heating / moisture goals - but would totally ruin the van. Number 2 would keep you warm - but would do nothing to reduce condensation - and depending on the heat source may even increase it. I believe every van builder should expect condensation, plan for it and manage it. So the question is where do you design the dew point. In a van it's naturally on the inside skin of the body. I do agree that wool hydroscopic, which means that rather just get wet and hold moisture it's able to take water into it's cells - so .... I know that when condensation occurs the wool will absorb it. The wool will hold it until the air out side the van is the same temperature or higher than the air inside(sun heating the outside of the van) At that point the air in the cavity will warm and take the moisture back as evaporation and the wool will be dry. In fact it's even better than that ..... "Wool insulation addresses both vapor diffusion and the issues with vapor barriers. One of wool's greatest strengths is its ability to manage moisture. It heats up when it absorbs moisture which helps maintain its R-value despite being wet which in turn helps it dry out quickly." It's a natural process that can happen over and over again. The observations you quoted "..... For Van Conversions" Key excerpts: Bare Plexiglass panel showing considerable condensation and beginning to drain down. Wool showing significant condensation, felt damp to touch on outer surface, (+36 g of water pickup). ....." are exactly what should be expected but the test didn't follow the full cycle of warm / cold / warm. In the end - Having spent time on the road - I believe van builders are insulating more for sound than for warmth. Thanks again for sharing your ideas ...... it's in the conversation ideas grow........ Be well and I hope you join the community..... Dave
@@VanOfAction "I do agree that wool [is] hydroscopic, which means that rather just get wet and hold moisture it's able to take water into it's cells - so .... I know that when condensation occurs the wool will absorb it." *...which is exactly what anyone with basic building science expertise knows must be avoided or at least drastically minimized.* Some other statements you made in your reply reveal that despite whatever practical trade experience you may have, you don't really understand the physics. You hare entitled to your strongly held opinions but the facts of any engineering problem are validated by careful objective testing, not by how strongly held or popular your opinions may be.
Well Video Pipeline - it finally happened. I knew when I started this channel that there would be videos that people would not agree with. It's part of the deal with putting your ideas out there. This particular video has been viewed over 30,000 times - which blows me away - and you are the first person to tell me I don't really know what I'm talking about. (I honestly thought the line would be longer). But it really means nothing to me. I'm sharing what I'm sharing because it's fun for me - there is nothing in it for me other than that. if people find it useful ... that's great. If people think it's wrong ...that's fine too. I know what I've built and I know how well it's working. I have no interest in trying to convince anyone I'm right. Earlier I suggested you join the community - I take it back. next time you scroll past my channel ... please do. Dave
Hi there, thankyou for your video. I live in Australia. Some parts of Australia is cold, some parts of the country is super hot and some parts in VERY RAINY and knowing me, i would probably living or staying in those rainy area due to the lush tropical weather ! I have just bought a toyota coaster and currently looking at converting it. I have watched people talked about foil boards, wools, ultra touch denim which there are none in australia to buy anyways, and apparently thinsulate is really good. But even that is quiet costly to import to australia. So we have earthwool that we use here, not sure about Havelock. Would you recommend this methods? Maybe simple is better with prevention condensation. It makes sense about wool absorbing moisture and releases it after like you said. Im not sure about foil boards. Also thankyou for the tips about install the insulation post cabinets frame work.
Hello Sunflower !!! It's so cool to me that someone where you are would watch the video I made in my little shop in the interior of BC !!!! Thanks for taking the time to comment. It sounds like your climate is very much like mine. We insulate for several reasons - keeping in the heat, keep out the heat, keeping sounds in and keeping sounds out. I expect every / any insulation will do these things to some extent. What some will do better than others is handle the moisture that will occur in the wall cavity - there is no question it's going to form there (unless a person uses a closed cell spray foam). Earthwool is a recycled glass product which appears to be a good insulator. However it would not absorb and release moisture as natural wool would. But if that's all you can get then you have to find a way to may it work. I'm not familiar with a toyota coaster so check to see if it's designed to allow interior moisture that will build up inside - if there are ways for the moisture to escape make sure that you leave them open. If there is no designed way for the moisture to escape - you'll have to give it some thought. I'm sure there will be a way to take care it. We also installed a Noika sound membrane on the walls, floor and ceiling to reduce vibration. In practice, we've found our insulation and the Noika have dramatically reduced the road noise and exterior sounds when parked - we don't even hear rain !!! But remember that a couple inches of any insulation will not keep your space warm when it's really cold out. Be well and let me know how you make out !!! Cheers
What about the floor? I have a transit and when I pulled the OEM rubber floor up (CCF pad under it) the floor was soaked from condensation so I wondered if that's going to be a problem if it's insulated since it won't breathe? Great video though, I looked today and the havlock is a 6 week delay. The whole vanlife world is buying it I guess.
I didn't do the floor when I did the walls - in fact I wish I had waited to do the walls and ceiling too. I don't know why people insulate so early in the process. Regarding the floor - I am starting it now. I'm only gioing to insulate (or put a floor) in the cabin where we walk. Not under the cabinets and not in the garage. I want the floor we walk on to be comfortable but I don't want to sacrifce the space a floor would take in the garage. For bikes every inch counts. In the cabin, I glued 1 inch sqare aluminum channel as a spacer, then added the sound deading and wool insulation in between.
On the floor would it help to add a sheet of thick plastic as a vapor barrier then bulid the floor frame and use havelock in the floor frame then attach plywood floor? Thoughts?
Hi six strings - Personally I would not add the plastic - in fact I didn't !!!! I don't think it's possible to create an air tight membrane on the floor, especially along the walls. I believe it's better to let things breathe. I framed my floor using 1" square aluminum tubing, glued to the tops of the ribs. I installed the aluminum at about 12 inch centers so I could use 1/2 in birch ply wood without sagging. Then I put the wool insulation in between. And then glued the plywood down. I thing the moisture in the 1 inch space will be minimal and air will be able to migrate in and out. I hope that helps. Insulation is such a debated subject in vans :) be well
As with the 3M Super 77 spray adhesive, I understand that the max temp to use is no more than 90 degrees fahrenheit. I do not know what the lowest temp to use is. Thus I figure "not too hot and not too cold", and not too much humidity.
Thanks for taking the time to watch and comment - it was about 45-50 F when I applied the insulation and it stuck great, The challenge is only the insulation that comes in contact with the glue sticks. The rest of the batt just hangs there and it pulls away very easily. I would insulate much later next time. Be well
Also metal conducts cold and heat. You should've covered all the metal. You left the struts uncovered, you could cover those too. And when you put up the panels you can still screw them on right thru the wool. I got that info from a Mechanical Engineer. Where you didn't put the wool after you put the walls up, on a cold day touch were you attached the panels to the struts and you'll feel it slightly cool because you didn't cover the struts. Won't be anything major but if you press your hand there and hold it there you'll feel the cool or heat on a hot or cold day.
Hi Joe - thanks for watching and taking the time to comment. I agree totally with the theory - but having used the van now for a while I'm convinced that the insulation is really more to control the moisture a bit and the sound a lot. In terms of keeping things warm it's really ineffective. Maxing out at a couple inches and with the heat loss through windows and the floor there really isn't much to it. Open a door once and you start from scratch all over again. We have used it in -12 C - It gets cold quickly - but warms up just as fast. But that heat just leaves ......... be well and stop back. Dave
@@VanOfAction Thank you for the update (and the video). I'm seeing others using the Havelock wool recently, and was considering it myself, but hearing that it doesn't do anything for the temperature is a dealbreaker. People are saying it has an R value of 3-4 per inch, which is the same as EPS foam board...I questioned that R value and it sounds like it's probably a lot lower than that. I am considering getting one box just to help manage moisture. Best wishes.
@@AndrewMagee01 The insulation discussion for vans is one that will probably go on forever. Having been in the van now for a couple years and used it in the cold let me share this. 1. No matter what you do you're gonna get condensation when the outside temp is much colder than the inside temp. So plan for where it's gonna occur and how you've gonna deal with it. As I said in the video, the wool is at the dew point and will absorb and release the moisture as circumstances change. I've had reason to expose some of the insulation along the way (other videos) and so far there has been absolutely no signs of mold or prolonged moisture. 2. And this is a biggy - No matter what insulation you use you'll retain very little (read none) heat in the van when it's cold outside. This is because you can't put in enough insulation to hold the heat and there are too many places for heat to escape. You'd need to build 6" think walls, floor and ceiling to properly protect the inside form freezing temps. And that makes no sense. Open the door long enough to get in and you've lost the inside air !!! If you plan on sitting in your van on a cold day - plan on a furnace running nonstop and plan on significant condensation, and plan on having REALLY COLD FEET. Thee vehicles just aren't big enough to build out for cold weather. Then why insulate ??? 1. It will help on fall and spring days for warmth 2. It's excellent for sound deadening. Our van runs really quietly and we hear very little outside noise when we are stopped and inside. Hope this helps .... and I hope you'll stop back and join the community ..... Be well Dave
What effect is gravity, in a moving vehicle - a vibrator essentially - going to have on wool batts, or fiberglass, or any batt (except rock wool which is structurally stiff)?
Hi Rusty Cas - thanks for visiting and commenting. I think insulation is the biggest debate of van building. Since I installed the insulation I've driven about 21,000 km (8 in 2021 and 13 in 2022) during that time I have had a number of the interior panels open on the inside to run wires or install something and I have found no insulation sagging or giving way. I didn't expect to though. I glued the wall batts in place and they are compressed to a degree when the interior finish is applied. I would not worry about the insulation giving way at all. And for the reasons I gave in the video I would not consider a rigid insulation at all. But that's just me !!! Be well and I hope you stop back.
Hi Danielle - thanks for watching and commenting. Some folks use thinsulate for sure. If installed properly it can change the location of the dew point - which for me was not wanted. If mice get into the van there are going to many problems, not jus the insulation so we take steps to keep the out. Be well and I hope you stop back. Dave
Wool batting same as used to make wool quilts. Do you have a wool processing company near you? I have one near me, here in Wisconsin. Prices are way different. Paying for import wool is expensive
Hi Theresa - thanks for watching and taking the time to comment - That is a fanstastic idea - I believe you are correct it would be exactly the same material. Can you share a link to the company ? I'd love to reach out to them and get some details. Hope you'll come back and see us again !! Dave
Hi Joe - thanks for watching and taking the time to comment. I'm sorry you didn't get what you wanted. But in my opinion, based on years of building many different types of construction in Canada - there really isn't anything to compare. Moisture is simply going to be a reality for any van build and Havelock wool is the only product that deals with it effectively in the wall cavity. I tried to communicate that. Be well and I hope you'll stop back.
Thanks Joe - this is a great point to bring up. First we have to agree that no matter what kind of insulation you use you're going to have condensation someplace. Spray foam - if it's "closed cell foam" will not let moisture into the wall cavity. But using spray foam creates 2 issues I wouldn't want to deal with. 1. It moves the "dew point" to the inside face of the foam. That's where the condensation will occur - and when it does there is no where for it to go. If the wall finish material is up against the insulation it'll get soggy, if it's installed air tight then the water will be dripping from the walls and ceiling into the cabin. 2. with the wall cavity filled solid running wires or pipes at a later date will be a problem. I think insulation is one of the most debated topics of a van build. But the reality is unless you build 6 inch walls, ceiling and floor you'll never be able insulate well enough to avoid the warm air and cold air meeting and creating condensation. The best we can do is design to manage it. Just my opinion - take it an $1.50 and you can get a coffee :) be well.
Hi Justin. Thanks for watching. - measure your van. The square footage (length x width) of the places you want to use the insulation. In my 3500 extended Promaster I needed about 340 sf. Be well and stop back……. Dave.
Hi OSO. Thanks for watching and commenting. Any insulation will help with sound - both sound coming in and sound going out. I can’t believe how quiet our van is - even driving !!!!! But no insulation will help with humidity. Humidity is going to happen. The goal is to try and make sure it doesn’t cause too much trouble. Hope I understood your question ?????
@@fuertep2do - Humidity is simply going to happen. Condensation happens when warm are meets cold air. So depending on the time of year and where you are you may have little (an area where the outside and inside of the van is always about the same - maybe northern USA or southern Canada in the summer) or you may get a ton of humidity (condensation).if you're in a place where it's very cold outside compared to the inside of the van ( anywhere there is a cold winter, maybe in the desert at times) Keeping the air moving will reduce it, so a fan in the van is a help. But in the walls the air will be still so you'll get it for sure. Hope that helps. Be well
Hi Stein. Thanks for watching and sharing your thoughts. I have never heard anything like that. I do know ….. The inherent flame-resistant properties of wool are related to its relatively high nitrogen (15%-16%) and sulfur (3%-4%) content, high moisture content (10%-14%) -- and if wet the moisture would seem to be higher. But that’s all theory. As a practical matter, there is. Not much insulation and it all (or very little) would ever be wet. So truthfully I would never let the gas issue out weigh all the proven benefits of natural wool insulation. Be well and stop back.
You didn't mention how its going to settle down your walls as its vibrated down the road. Then it's R0 because I'd the whole wall isn't insulated its only slightly better than having no insulation.
Hi Samuel -thanks for watching and taking the time to comment. I didn't mention that = and after 3 years that hasn't been my experience at all. If you watch some other videos of mine you'd find that almost all of my interior finishes and cabinet liners are removable. So I can run wires or other stuff. I've had every wall open over time and I've seen no settling at all. but maybe time will prove you right - at which time I'll able to correct if needed. Hope you'll stop back .... Dave
Hi N Martin - thanks for watching !!! We bought 3 bags of the batts - used it everywhere and have about 1/4 of a bag left over. Hope that helps !!! Be well and come back.
Hey Brett. Thanks for watching and taking the time to comment. I’m not completely clear what you mean. I’m pretty sure my build sequence was different than most. Partly by design and partly because of Covid’s impact on the availability of materials. But - I also didn’t publish my build videos in the exact order they were shot. At this point - if you visit the channel you should see it all and I’ve tried to curate the videos in a way that makes sense (at least to me). Happy new year and be well………. Dave
Hoho - thanks for watching and taking the time to post a comment. What you said is true. But it does not apply to this instance. Let me explain without trying to lecture. Other folks may not understand your point. “Condensation” occurs when cold air and warm air meet - it’s called the dew point. “Ventilation ” means the air is moving. And there’s no question if air is moving it will not condense. However- in a van the dew point (- where condensation will occur - always on the warm side) is at the inside skin of the van or the outside edge of the insulation. What makes insulation effective is it’s ability to hold air still - so to have ventilation at the inside face of the van would require not having anything to stop the air from moving. So no insulation. and a mechanical way to introduce air movement inside the wall. So you’d have a cold drafty van. If there is insulation - there is going to be condensation at times. There’s no getting around it…… Be well my friend.
did u get paid from Havelock wool company. if not, i try to believe u because too many in you tube try to say something when they got paid from that brand. this is confuse me too much. i do not know who should i believe.
Yeezuz lex. Thanks for watching and asking a great question. I receive NOTHING from anyone on my website. I agree - I’ve watched a ton of videos that are crap and sales pitches. I have lots of experience. I’m offering my truest and most honest opinion a s hope that it’s helpful to others.
In my view, wool is nowhere near as good an insulation method as closed celll foam, which acts as not only an excellent heat/cold insulator and noise insulator, but also eliminates the need for the stick-on sound deadening material, and acts as a very effective moisture barrier (moisture comes from INSIDE the van - our breath and cooking vapors and showers are primary moisture contributors here), and it stiffens and strengthens the entire van structure. Messy and expensive and care need to be taken about access to wires/plumbing etc as necessary, YES, but so worth it in the end result!
Hi Barry. Thanks for watching and taking the time to comment. Insulation and moisture are probably the most debated components in van building. I am really happy with the wool I used and can’t imagine anything being better. But I understand not everyone will agree and it’s in that conversation others will learn. Be well and stop back. Dave.
Hi 1marshall1me .... THANKS for watching the video and actually reading the comments !!!!!! I don't believe that's the case at all.

Cheers .. Dave
Ray !!! Thanks for taking the time to watch the video - but more so to let me know about the title. As an old builder rockwool is my default for insuation - which is bad when it should have be "Havelock" wool - the change has been made, be well
All the houses I've seen built have vapor barriers on the outside and none on the inside.... Except maybe paint and caulking if you count that. Aren't you concerned that wool will absorb moisture. Wool does absorb water. There are synthetic materials that don't absorb water you could use. I'd be interested in seeing the lower portion of your panels inside now after some years to see if they have started to rust due to moisture build up.
Hi Kel. I’d like to say thanks for watching - but it feels like maybe you didn’t. I do appreciate you taking the time to comment. I’ll reply in the order you used. 1. I think your mistaken about where the vapour barrier is in homes. The barrier goes where the “dew point” is - where the warmer air meets cooler air. In a home that’s on the inside of the insulation. You want to keep the warm moist air from going into the insulation, Where condensation will get the insulation wet. The warmth may radiate in - but the moisture will not. As I said in the video - in a van that point is on the inside face of the van panel - in the insulation - because I don’t believe it’s possible to create a perfect barrier on the inside of the wall. 2. Yes as discussed in the video - the wool will absorb the moisture - that’s the whole reason for using it over other insulation. It will absorb it and then release It when the humidity changes without changing it’s ability to insulate. The synthetic materials that don’t absorb water still get wet, and moldy and stop insulating. 3. This is the second winter and I had a panel exposed to run some wires - all is good inside. Thanks for stopping by - be well and come back.
Hi Jacob - thanks for watching and taking the time to comment. YES !! Wool acts like a wick and absorbs the moisture. There are a number of products that do that - but wool is the only one I'm aware of that will later release the moisture without it's ability to insulate being effected. Be sure to stop back ... Dave
Nope. Your first centence was "I did it wrong". You got that part right... We used spray foam insulation on the ceiling and walls. No doors. Except side slider. Do NOT force insulation in to cubby holes or lower doors because you cover factory drain holes. In the late 1970's and 1980's we did 1000's of vans and no worries.
HI Harley - thanks so much for watching the video and taking the time to comment. I love it when people share their thoughts and opinions - I think it helps everyone learn. I had to re-watch the video. I understand and agree with your point about the drain holes when using spray foam insulation (assuming you're using a closed cell spray - you'd be crazy to use open cell). Because closed cell doesn't breath it would absolutely trap the moisture that's going to form on the inside of the panels in those areas where there is no insulation, or on the inside of the insulation on a cold day. That water has to have a place to go. I hand mentioned the drain holes when shooting but didn't include include them in the final cut because with wool insulation the point is moot. The wool I used will take on moisture and release it back out - if there's enough, with gravity that moisture will migrate down and out the drain holes. The holes are not plugged at all. I don't know but I doubt natural wool was very common when you were doing vans. In my opinion it's a superior product and easier for a DIY person to work with. It's great to understand how all the systems work together. Be well and stop back my friend.
Your thumbnail says best van insulation and why. Pure clickbait. You basically said trust me, I did my research and picked Havelock wool without presenting any fact based why. Wool is a valid consideration, but it's one of many and there are tradeoffs to all of them. This felt more like an infomercial and is very disappointing. Opinion is not useful when attempting to evaluate the different insulation options on the market.
Hi Chris - thanks for watching and taking the time to comment - I really appreciate your thoughts. I'm sorry you found the advertised point of the video misleading - That was never the intention but with your help I can see how it would happen. I have changed the thumbnail. All my videos are completely my opinion. There has never been affiliate links or sponsors - Not selling anything - ) I'm simply sharing my thoughts as completely as I can - (even the stuff I've invented). Insulation is one of the areas there is great debate between van builders. My feeling is that many people think that because you're insulating you can eliminate the moisture in the wall. I don't believe that's possible, and because of that I believe natural wool is the only practical solution - which is what I tried to communicate in the video. But it's all just my opinion and as I'm often reminded here at home, my opinion and $ 1.50 will get you a coffee at McDonalds. If you are inclined I'd invite you to watch this comparison of D.I.Y. wiring and a store bought power system from Bluetti. th-cam.com/video/5Lzgq2LlGTA/w-d-xo.html I hope you'll stop back. Be well .
@@VanOfAction We all have our opinions which are formed by our own personal ratio of knowledge, ignorance, and starting bias. Where things get questionable and fuzzy is when they start to be represented as facts or knowledge overstated. Sadly TH-cam rewards clickbait titles with things like 'best xxx' titles, and our culture rewards hyperbole when selling things. Channel creators are selling themselves as 'experts' or often shilling products/services for others. As someone trying to learn it can be hard to sift through tons of videos to find a few golden nuggets of useful information. I did like your installation tips on installing wool and the importance of keeping it in place so it can be covered and held in place before it get damaged or falls off. Best wishes with your channel.
@@VanOfAction I think that you did a great job explaining your reasoning on why you've chose to use wool for insulating. There is some some things that just happen to be common sense or our own conclusions based on experiences we've had through-out life with the history of usage. Although you are certainly not old, by any means, your graying hair tells me that you've been around for a minute and I'm pretty sure that you have learned a thing or two about a thing or two, lol. One being that no matter what you do or say, you just cannot please everyone. ANYHOO, I myself have been in the process of renovating a travel trailer and have unfortunatly found mold. So my husband and I have been trying to decide what type of insulation we should use & because I have a few thousand pounds of jumbo chunky wool, ( I make those beautiful jumbo chunky blankets that you see being sold on Etsy or instructional videos here on YT on how to arm knit one) we've strongly discussed doing so, SO..... THANK YOU for sharing your video. I don't believe that we've come across a video yet that has discussed or talked about using wool for insulation. Was happy to have finally found one & I'll be SUBBING plus leaving a THUMBS-UP. OH, and of course, we'll be looking forward to viewing more of your videos. Take Care and KEEP SMILING! a new subb and fan, CHERI from SLC, UTAH~
@@cherigibsontrujillo2610 Hi Cheri. Wow thanks for the kind words but more importantly thanks for reading the comments ! That’s awesome. I think you’re right, if you have access to natural wool that is your best bet. When I started I thought I was insulating for heat retention and to help keep the van cool on hot days. But experience has shown me that there simply isn’t enough insulation to be effective with either. The greatest benefit (which may not be as important in a trailer) is the sound proofing the insulation provides. That part is amazing. BUT - With so little insulation - condensation is going to be a reality. Managing it is critical. And allowing air to move (the system to breath) - or the condensation to drain is the secret. I would suggest you plan for both those things. Mold will occur when moisture is allowed to sit against a material such as wood which is an easy place for mold to grow. So just plan for it. Thanks too for your generous opinion about how decrepit I am. I didn’t reply immediately because we’re on the “Great 2023 Road Trip”. Which took us through Utah about a week ago. On our way to Santa Fe. We camped at Willard Bay State Park which was nice (right beside the highway). And I have to tell you I would never have imagined how beautiful Utah is. We were blown away……… be well and let me know how you make out.
@@VanOfAction I sure will. Actually, we've thought about hanging some beautifully made & thick as hell blankets on a few walls and some gorgeous cow hyde rugs too. Maybe even on the ceilings....? It's like falling into a hole when going over all the information & listening to others' experiences with their insulation of choice. We are honestly stuck and haven't a dang clue as to what we are going to use. WHAT A MESS, lol. Anyhow, how fantastic to hear you enjoyed it Here in Utah. I live in a lovely city called Sandy, which is 15 mins south of downtown Salt Lake. It's kind of near the prison, well maybe 20n mins or so northeast. We r right down the street from the REAL soccer stadium. They are a fairly new team and have a beautiful soccer field, just happy that we got some sort of sporting since we'll never have football bcuz the Mormons, lol. Well, you take care n have lots of fun on your trip. And remember to ALWAYS BE SAFE OUT THERE! It's so fantastic to have heard from you. SAFE TRAVELS~ your Utah fan, CHERI 😋 👍 ❤

Your explanation re moisture barrier and hydroscopic was insightful. Thanks for the tips!
Vincent - thanks for watching !!
I just wanted to commend you on your replies to some of the comments that seem quite critical of your method of insulation. This seems to be almost an emotional subject to some. Personally for myself in my '20 Promaster Im using thinsulate on the large flat surfaces, leaving the large cavities at the roofline sides and down the ribs along the sides open and free as an air passage way though all ribs are covered on the living side surface with 1" R Max. All four corners at the ceiling have 4" computer fans built in drawing air after a humidity event from the floor area through the ribs of the van into the living space and expelled by the 2 Max Airs vent on the roof. Absolutely no inner vapor barrier for me as the outer sheet metal of the van is a given vapor barrier and I dont want to trap moisture between two vapor barriers.
Hi JG-k4oi - thanks so much for watching and taking the time to comment - I believe it's in the conversation we learn and grow. I don't have to be right. - yes - insulation sure gets the blood going. So many different ways to it. I'm intrigued with your use of the fans. I agree with the concept but I'm not certain of the effectiveness in extreme colds. The difference in temperatures outside / inside and the small R value of any insulation is going to cause condensation - maybe not where the air is moving - but at the dew point of the system everywhere else. But that's just me ... let me know how it works. I hope you'll join the community and stop back. ..... Dave

Hi Daniel - thanks for coming by and taking the time to comment. I wish you well ... Dave
@ 2:42 You almost got this right here, but you omitted the now-standard Tyvek housewrap (barrier) that effectively prevents moisture infiltration from the outside of any modern residential construction. @ 3:19 "...but in a van, the outside layer is the vapor barrier.. ...we're almost turning our [conventional building] system inside out..." In a metal building (or a van) you have barriers on *both* sides, preferably with impermeable thermal resistive insulation (i.e.: has an R-Value) in btween.
Hi Video Pipeline - thank you so much for watching the video and taking the time to make such a detailed comment. I love these - I believe that it's in the conversation that people learn and form their ideas. I know there are a ton of people lurking here. And my experience in van building is that there can be tremendous differences between the theoretical building concepts and how things actually work ...... * Yes* - I did omit the Tyvek housewrap - which is a very effective moisture barrier for air coming into a house. However, I disagree with the comment that " ..... In a metal building (or a van) you have barriers on both sides,...." you'll only have 2 barriers if you build in 2 barriers and I don't believe it's possible to do that on the inside of a van without using a closed cell spray foam. A product that would totally change the build. In my opinion it would not be practical to try to create a wall cavity that was completely sealed on both sides. And even if it was possible, given the small amount of insulation in that cavity all you would accomplish for the effort is a moving of the dew point - because there's gonna be one. The question is where is it best managed. For my van , where and how I use it I'm happy with the results. ..... Be well and I hope you'll stop back ..... Dave
@@VanOfAction re: "I did omit the Tyvek housewrap - which is a very effective moisture barrier for air coming into a house." As you probably know, the benefit of Tyvek (and subsequent comparable products) is reduced wind infiltration and bi-directional vapor permeability, so if resists wind pressure driven moisture laden air from entering the wall cavity, but more readily permits moisture to escape from the wall cavity. This is almost exactly the opposite of how wool performs when used as bulk insulation in a wall cavity (metal buildiong or van makes no difference).
"In my opinion it would not be practical to try to create a wall cavity that was completely sealed on both sides." Herrmetically sealed is not typically possible, but sealed to the typical vapor pressures encountered certainly is, and in fact new buildings in coastal areas are typically built to this standard. Some people don't want to seal off the inside surface of a vehicle skin due to concerns about making collision damage repair more difficult. To each their own, I guess, but IMO that's a strange prioritization.
"And even if it was possible, given the small amount of insulation in that cavity all you would accomplish for the effort is a moving of the dew point - because there's gonna be one." In cold exterior temperatures, the dew point will be on the outside. The primary rationale for using thermal insulation is to allow living spaces to be conditioned, in which case there will be no condensation on the inside walls even when the space is relatively full of breathing occupants.
Hi Video Pipeline - thanks for taking the time to respond. You clearly have a concrete grasp on the theory of building envelopes. I don't expect you've ever built or spent time in a van. If you ever do you will be able to insulate any way you want, I'm very happy with the method I used and would recommend it to anyone...... Dave
Thank you for sharing...I appreciate having access to honest hindsight before I get started. I am allergic to wool so that mandates a different product... pretty sure i will be using the thinsulate... but putting it in after structure is good math lol
Hi Jess - yep, I wish I had waited - it seemed like the first thing to do but then you fight with it every day. I'm sure you'll find a systemt that works but be aware of condensation .... be well
Jess thanks for bringing up the allergy. I didn't even think of that since I don't wear wool. I have a lot of allergies and will have to look into that.

Did you take any measures against the thermal bridging that occurs on the structural metal that your wooden framing is attached to?
Hi David. Thanks for watching and commenting. I did not. All in we’re talking about 2 maybe 2 1\2 inches of insulation. I believe it’s possible to over analyze things.

Hi Rachel - thanks for watching and commenting. There are a million different opinions about vapour barriers.

@5:23 "Wool is hydroscopic..." which is one of the main reasons *wool should not be used to insulate a camper van* that's not in a very dry climate. Two other reasons: high cost per unit R-value & relatively low R-Value per unit thicknesss. Wool makes a great blanket or sweater, but it's a poor choice for thermal insulation in a structure (or RV) exposed to RH above 50%. To better understand why, refer to these two tests that done by Gary @ Build a Green RV: "Water absorption for various insulation types" & "Insulation Testing - For Van Conversions" Key excerpts: Bare Plexiglass panel showing considerable condensation and beginning to drain down. Wool showing significant condensation, felt damp to touch on outer surface, (+36 g of water pickup). Thinsulate showing significant condensation, (+11 g of water pickup). Polyiso showing no condensation. Polyiso felt dry, (+0 g of water pickup)
Hi Video Pipeline - again, thanks for watching and taking the time to comment. Insulation is one of the topics of a van build that I think will be a never ending debate - this will probably be a long answer, I think it's important but I can't do another video about it right now. In this case, because of what I consider the insulation is for - I disagree with just about everything you've said.
I am in Canada, the interior of British Columbia. I don't use my van in the dead of winter but I do use in during the shoulder months when night time temperatures will dip to below freezing.
Having said that - there is not a product on the market that will insulate the walls, ceiling and floor of a van with enough R-value to enable the interior to hold heat well enough to maintain a consistent temperature if it's cold outside. If you want the inside to stay warm you have 2 choices. 1. build everything thick enough to hold enough insulation or 2. have to have a constant heat source.
Number 1 would accomplish the heating / moisture goals - but would totally ruin the van.
Number 2 would keep you warm - but would do nothing to reduce condensation - and depending on the heat source may even increase it.
I believe every van builder should expect condensation, plan for it and manage it. So the question is where do you design the dew point. In a van it's naturally on the inside skin of the body. I do agree that wool hydroscopic, which means that rather just get wet and hold moisture it's able to take water into it's cells - so .... I know that when condensation occurs the wool will absorb it. The wool will hold it until the air out side the van is the same temperature or higher than the air inside(sun heating the outside of the van) At that point the air in the cavity will warm and take the moisture back as evaporation and the wool will be dry. In fact it's even better than that ..... "Wool insulation addresses both vapor diffusion and the issues with vapor barriers. One of wool's greatest strengths is its ability to manage moisture. It heats up when it absorbs moisture which helps maintain its R-value despite being wet which in turn helps it dry out quickly." It's a natural process that can happen over and over again.
The observations you quoted "..... For Van Conversions" Key excerpts: Bare Plexiglass panel showing considerable condensation and beginning to drain down. Wool showing significant condensation, felt damp to touch on outer surface, (+36 g of water pickup). ....." are exactly what should be expected but the test didn't follow the full cycle of warm / cold / warm.
In the end - Having spent time on the road - I believe van builders are insulating more for sound than for warmth.
Thanks again for sharing your ideas ...... it's in the conversation ideas grow........ Be well and I hope you join the community..... Dave
@@VanOfAction "I do agree that wool [is] hydroscopic, which means that rather just get wet and hold moisture it's able to take water into it's cells - so .... I know that when condensation occurs the wool will absorb it." *...which is exactly what anyone with basic building science expertise knows must be avoided or at least drastically minimized.* Some other statements you made in your reply reveal that despite whatever practical trade experience you may have, you don't really understand the physics. You hare entitled to your strongly held opinions but the facts of any engineering problem are validated by careful objective testing, not by how strongly held or popular your opinions may be.

Hi there, thankyou for your video. I live in Australia. Some parts of Australia is cold, some parts of the country is super hot and some parts in VERY RAINY and knowing me, i would probably living or staying in those rainy area due to the lush tropical weather !
I have just bought a toyota coaster and currently looking at converting it.
I have watched people talked about foil boards, wools, ultra touch denim which there are none in australia to buy anyways, and apparently thinsulate is really good. But even that is quiet costly to import to australia. So we have earthwool that we use here, not sure about Havelock.
Would you recommend this methods?
Maybe simple is better with prevention condensation. It makes sense about wool absorbing moisture and releases it after like you said.
Im not sure about foil boards.
Also thankyou for the tips about install the insulation post cabinets frame work.
Hello Sunflower !!! It's so cool to me that someone where you are would watch the video I made in my little shop in the interior of BC !!!! Thanks for taking the time to comment. It sounds like your climate is very much like mine. We insulate for several reasons - keeping in the heat, keep out the heat, keeping sounds in and keeping sounds out. I expect every / any insulation will do these things to some extent. What some will do better than others is handle the moisture that will occur in the wall cavity - there is no question it's going to form there (unless a person uses a closed cell spray foam).
Earthwool is a recycled glass product which appears to be a good insulator. However it would not absorb and release moisture as natural wool would. But if that's all you can get then you have to find a way to may it work. I'm not familiar with a toyota coaster so check to see if it's designed to allow interior moisture that will build up inside - if there are ways for the moisture to escape make sure that you leave them open. If there is no designed way for the moisture to escape - you'll have to give it some thought. I'm sure there will be a way to take care it. We also installed a Noika sound membrane on the walls, floor and ceiling to reduce vibration.
In practice, we've found our insulation and the Noika have dramatically reduced the road noise and exterior sounds when parked - we don't even hear rain !!! But remember that a couple inches of any insulation will not keep your space warm when it's really cold out.
Be well and let me know how you make out !!! Cheers
What about the floor? I have a transit and when I pulled the OEM rubber floor up (CCF pad under it) the floor was soaked from condensation so I wondered if that's going to be a problem if it's insulated since it won't breathe? Great video though, I looked today and the havlock is a 6 week delay. The whole vanlife world is buying it I guess.
I didn't do the floor when I did the walls - in fact I wish I had waited to do the walls and ceiling too. I don't know why people insulate so early in the process. Regarding the floor - I am starting it now. I'm only gioing to insulate (or put a floor) in the cabin where we walk. Not under the cabinets and not in the garage. I want the floor we walk on to be comfortable but I don't want to sacrifce the space a floor would take in the garage. For bikes every inch counts. In the cabin, I glued 1 inch sqare aluminum channel as a spacer, then added the sound deading and wool insulation in between.
On the floor would it help to add a sheet of thick plastic as a vapor barrier then bulid the floor frame and use havelock in the floor frame then attach plywood floor? Thoughts?
Hi six strings - Personally I would not add the plastic - in fact I didn't !!!! I don't think it's possible to create an air tight membrane on the floor, especially along the walls. I believe it's better to let things breathe. I framed my floor using 1" square aluminum tubing, glued to the tops of the ribs. I installed the aluminum at about 12 inch centers so I could use 1/2 in birch ply wood without sagging. Then I put the wool insulation in between. And then glued the plywood down. I thing the moisture in the 1 inch space will be minimal and air will be able to migrate in and out. I hope that helps. Insulation is such a debated subject in vans :) be well
As with the 3M Super 77 spray adhesive, I understand that the max temp to use is no more than 90 degrees fahrenheit. I do not know what the lowest temp to use is. Thus I figure "not too hot and not too cold", and not too much humidity.
Thanks for taking the time to watch and comment - it was about 45-50 F when I applied the insulation and it stuck great, The challenge is only the insulation that comes in contact with the glue sticks. The rest of the batt just hangs there and it pulls away very easily. I would insulate much later next time. Be well
Also metal conducts cold and heat. You should've covered all the metal. You left the struts uncovered, you could cover those too. And when you put up the panels you can still screw them on right thru the wool. I got that info from a Mechanical Engineer. Where you didn't put the wool after you put the walls up, on a cold day touch were you attached the panels to the struts and you'll feel it slightly cool because you didn't cover the struts. Won't be anything major but if you press your hand there and hold it there you'll feel the cool or heat on a hot or cold day.
Hi Joe - thanks for watching and taking the time to comment. I agree totally with the theory - but having used the van now for a while I'm convinced that the insulation is really more to control the moisture a bit and the sound a lot. In terms of keeping things warm it's really ineffective. Maxing out at a couple inches and with the heat loss through windows and the floor there really isn't much to it. Open a door once and you start from scratch all over again. We have used it in -12 C - It gets cold quickly - but warms up just as fast. But that heat just leaves ......... be well and stop back. Dave
@@VanOfAction Thank you for the update (and the video). I'm seeing others using the Havelock wool recently, and was considering it myself, but hearing that it doesn't do anything for the temperature is a dealbreaker. People are saying it has an R value of 3-4 per inch, which is the same as EPS foam board...I questioned that R value and it sounds like it's probably a lot lower than that. I am considering getting one box just to help manage moisture. Best wishes.
@@AndrewMagee01 The insulation discussion for vans is one that will probably go on forever. Having been in the van now for a couple years and used it in the cold let me share this. 1. No matter what you do you're gonna get condensation when the outside temp is much colder than the inside temp. So plan for where it's gonna occur and how you've gonna deal with it. As I said in the video, the wool is at the dew point and will absorb and release the moisture as circumstances change. I've had reason to expose some of the insulation along the way (other videos) and so far there has been absolutely no signs of mold or prolonged moisture. 2. And this is a biggy - No matter what insulation you use you'll retain very little (read none) heat in the van when it's cold outside. This is because you can't put in enough insulation to hold the heat and there are too many places for heat to escape. You'd need to build 6" think walls, floor and ceiling to properly protect the inside form freezing temps. And that makes no sense. Open the door long enough to get in and you've lost the inside air !!! If you plan on sitting in your van on a cold day - plan on a furnace running nonstop and plan on significant condensation, and plan on having REALLY COLD FEET. Thee vehicles just aren't big enough to build out for cold weather. Then why insulate ??? 1. It will help on fall and spring days for warmth 2. It's excellent for sound deadening. Our van runs really quietly and we hear very little outside noise when we are stopped and inside. Hope this helps .... and I hope you'll stop back and join the community ..... Be well Dave

What effect is gravity, in a moving vehicle - a vibrator essentially - going to have on wool batts, or fiberglass, or any batt (except rock wool which is structurally stiff)?
Hi Rusty Cas - thanks for visiting and commenting. I think insulation is the biggest debate of van building. Since I installed the insulation I've driven about 21,000 km (8 in 2021 and 13 in 2022) during that time I have had a number of the interior panels open on the inside to run wires or install something and I have found no insulation sagging or giving way. I didn't expect to though. I glued the wall batts in place and they are compressed to a degree when the interior finish is applied. I would not worry about the insulation giving way at all. And for the reasons I gave in the video I would not consider a rigid insulation at all. But that's just me !!! Be well and I hope you stop back.
What about thinsulate for insulation? What about mice and such?
Hi Danielle - thanks for watching and commenting. Some folks use thinsulate for sure. If installed properly it can change the location of the dew point - which for me was not wanted. If mice get into the van there are going to many problems, not jus the insulation so we take steps to keep the out. Be well and I hope you stop back. Dave
Wool batting same as used to make wool quilts. Do you have a wool processing company near you? I have one near me, here in Wisconsin. Prices are way different. Paying for import wool is expensive

Great video thanks
Thank you for taking the time
I came to see good comparisons, but instead got a PR piece for havelock
Hi Joe - thanks for watching and taking the time to comment. I'm sorry you didn't get what you wanted. But in my opinion, based on years of building many different types of construction in Canada - there really isn't anything to compare. Moisture is simply going to be a reality for any van build and Havelock wool is the only product that deals with it effectively in the wall cavity. I tried to communicate that. Be well and I hope you'll stop back.
@@VanOfAction Spray foam eliminates the gap, eliminates moisture, yeah?
Thanks Joe - this is a great point to bring up. First we have to agree that no matter what kind of insulation you use you're going to have condensation someplace. Spray foam - if it's "closed cell foam" will not let moisture into the wall cavity. But using spray foam creates 2 issues I wouldn't want to deal with. 1. It moves the "dew point" to the inside face of the foam. That's where the condensation will occur - and when it does there is no where for it to go. If the wall finish material is up against the insulation it'll get soggy, if it's installed air tight then the water will be dripping from the walls and ceiling into the cabin. 2. with the wall cavity filled solid running wires or pipes at a later date will be a problem. I think insulation is one of the most debated topics of a van build. But the reality is unless you build 6 inch walls, ceiling and floor you'll never be able insulate well enough to avoid the warm air and cold air meeting and creating condensation. The best we can do is design to manage it. Just my opinion - take it an $1.50 and you can get a coffee :) be well.
So Havelock Wool sells a pallet that says it will cover 1200 s/f. Is that sufficient for a van build like this?
Hi Justin. Thanks for watching. - measure your van. The square footage (length x width) of the places you want to use the insulation. In my 3500 extended Promaster I needed about 340 sf. Be well and stop back……. Dave.
Nice video tha helps me a lot. But i have another question i have to put some insulation. I have. R15 insulation tha helps with sound and humidity?
Can you really help me with that plz.
Hi OSO. Thanks for watching and commenting. Any insulation will help with sound - both sound coming in and sound going out. I can’t believe how quiet our van is - even driving !!!!! But no insulation will help with humidity. Humidity is going to happen. The goal is to try and make sure it doesn’t cause too much trouble. Hope I understood your question ?????
@@VanOfAction thank's that really help me anything else you think can help me to prevent humanity
@@fuertep2do - Humidity is simply going to happen. Condensation happens when warm are meets cold air. So depending on the time of year and where you are you may have little (an area where the outside and inside of the van is always about the same - maybe northern USA or southern Canada in the summer) or you may get a ton of humidity (condensation).if you're in a place where it's very cold outside compared to the inside of the van ( anywhere there is a cold winter, maybe in the desert at times) Keeping the air moving will reduce it, so a fan in the van is a help. But in the walls the air will be still so you'll get it for sure. Hope that helps. Be well

The inherent flame-resistant properties of wool are related to its relatively high nitrogen (15%-16%) and sulfur (3%-4%) content, high moisture content (10%-14%) -- and if wet the moisture would seem to be higher. But that’s all theory. As a practical matter, there is. Not much insulation and it all (or very little) would ever be wet. So truthfully I would never let the gas issue out weigh all the proven benefits of natural wool insulation. Be well and stop back.
You didn't mention how its going to settle down your walls as its vibrated down the road. Then it's R0 because I'd the whole wall isn't insulated its only slightly better than having no insulation.
Hi Samuel -thanks for watching and taking the time to comment. I didn't mention that = and after 3 years that hasn't been my experience at all. If you watch some other videos of mine you'd find that almost all of my interior finishes and cabinet liners are removable. So I can run wires or other stuff. I've had every wall open over time and I've seen no settling at all. but maybe time will prove you right - at which time I'll able to correct if needed. Hope you'll stop back .... Dave
How much did you order for the size of your van?
Hi N Martin - thanks for watching !!! We bought 3 bags of the batts - used it everywhere and have about 1/4 of a bag left over. Hope that helps !!! Be well and come back.
but why did he wait 3 monthes to panel? and do cabinets..
Hey Brett. Thanks for watching and taking the time to comment. I’m not completely clear what you mean. I’m pretty sure my build sequence was different than most. Partly by design and partly because of Covid’s impact on the availability of materials. But - I also didn’t publish my build videos in the exact order they were shot. At this point - if you visit the channel you should see it all and I’ve tried to curate the videos in a way that makes sense (at least to me). Happy new year and be well………. Dave
Why do people who talk about insulation never mention ventilation? Ventilation is always the best way to stop damp.
Hoho - thanks for watching and taking the time to post a comment. What you said is true. But it does not apply to this instance. Let me explain without trying to lecture. Other folks may not understand your point. “Condensation” occurs when cold air and warm air meet - it’s called the dew point. “Ventilation ” means the air is moving. And there’s no question if air is moving it will not condense. However- in a van the dew point (- where condensation will occur - always on the warm side) is at the inside skin of the van or the outside edge of the insulation. What makes insulation effective is it’s ability to hold air still - so to have ventilation at the inside face of the van would require not having anything to stop the air from moving. So no insulation. and a mechanical way to introduce air movement inside the wall. So you’d have a cold drafty van. If there is insulation - there is going to be condensation at times. There’s no getting around it…… Be well my friend.
I had to subscribe
:). So glad you did. :). And thanks for saying so. Be well.
did u get paid from Havelock wool company. if not, i try to believe u because too many in you tube try to say something when they got paid from that brand. this is confuse me too much. i do not know who should i believe.
Yeezuz lex. Thanks for watching and asking a great question. I receive NOTHING from anyone on my website. I agree - I’ve watched a ton of videos that are crap and sales pitches. I have lots of experience. I’m offering my truest and most honest opinion a s hope that it’s helpful to others.
@@chomztvshorts8201 THANK YOU SO MUCH
In my view, wool is nowhere near as good an insulation method as closed celll foam, which acts as not only an excellent heat/cold insulator and noise insulator, but also eliminates the need for the stick-on sound deadening material, and acts as a very effective moisture barrier (moisture comes from INSIDE the van - our breath and cooking vapors and showers are primary moisture contributors here), and it stiffens and strengthens the entire van structure. Messy and expensive and care need to be taken about access to wires/plumbing etc as necessary, YES, but so worth it in the end result!
Hi Barry. Thanks for watching and taking the time to comment. Insulation and moisture are probably the most debated components in van building. I am really happy with the wool I used and can’t imagine anything being better. But I understand not everyone will agree and it’s in that conversation others will learn. Be well and stop back. Dave.
The wool will attract bugs, no way around it.
What do you mean? How so?
Hi 1marshall1me .... THANKS for watching the video and actually reading the comments !!!!!! I don't believe that's the case at all. In fact just yesterday as I was preparing to install new second seats I cut out some floor and exposed the insulation .... it looked like new ....... Be well and stop back Dave
It's the wool off a animal, and animals get a slew of bugs ,fleas,lice,etc
@@susananderson9619 It is off of an animal - however it isn't shipped right after the cut it off. They clean and treat it first - you'll see more information here ..... havelockwool.com/van-insulation-products/#:~:text=We%20apply%20a%20minor%20amount,toxic%2C%20as%20an%20insect%20repellent. ... scroll down to the 3rd last question ... Cheers .. Dave
Your title is misleading. It says rockwool, but you’re not using it.
Ray !!! Thanks for taking the time to watch the video - but more so to let me know about the title. As an old builder rockwool is my default for insuation - which is bad when it should have be "Havelock" wool - the change has been made, be well
All the houses I've seen built have vapor barriers on the outside and none on the inside.... Except maybe paint and caulking if you count that. Aren't you concerned that wool will absorb moisture. Wool does absorb water. There are synthetic materials that don't absorb water you could use. I'd be interested in seeing the lower portion of your panels inside now after some years to see if they have started to rust due to moisture build up.
Hi Kel. I’d like to say thanks for watching
- but it feels like maybe you didn’t. I do appreciate you taking the time to comment. I’ll reply in the order you used. 1. I think your mistaken about where the vapour barrier is in homes. The barrier goes where the “dew point” is - where the warmer air meets cooler air. In a home that’s on the inside of the insulation. You want to keep the warm moist air from going into the insulation, Where condensation will get the insulation wet. The warmth may radiate in - but the moisture will not. As I said in the video - in a van that point is on the inside face of the van panel - in the insulation - because I don’t believe it’s possible to create a perfect barrier on the inside of the wall. 2. Yes as discussed in the video - the wool will absorb the moisture - that’s the whole reason for using it over other insulation. It will absorb it and then release
It when the humidity changes without changing it’s ability to insulate. The synthetic materials that don’t absorb water still get wet, and moldy and stop insulating. 3. This is the second winter and I had a panel exposed to run some wires - all is good inside. Thanks for stopping by - be well and come back.
Wool whisks away moister that's why the military uses wool products to keep soldiers warm and dry.
Hi Jacob - thanks for watching and taking the time to comment. YES !! Wool acts like a wick and absorbs the moisture. There are a number of products that do that - but wool is the only one I'm aware of that will later release the moisture without it's ability to insulate being effected. Be sure to stop back ... Dave
Nope.
Your first centence was "I did it wrong".
You got that part right...
We used spray foam insulation on the ceiling and walls. No doors.
Except side slider.
Do NOT force insulation in to cubby holes or lower doors because you cover
factory drain holes.
In the late 1970's and 1980's we did 1000's of vans and no worries.
HI Harley - thanks so much for watching the video and taking the time to comment. I love it when people share their thoughts and opinions - I think it helps everyone learn. I had to re-watch the video. I understand and agree with your point about the drain holes when using spray foam insulation (assuming you're using a closed cell spray - you'd be crazy to use open cell). Because closed cell doesn't breath it would absolutely trap the moisture that's going to form on the inside of the panels in those areas where there is no insulation, or on the inside of the insulation on a cold day. That water has to have a place to go. I hand mentioned the drain holes when shooting but didn't include include them in the final cut because with wool insulation the point is moot. The wool I used will take on moisture and release it back out - if there's enough, with gravity that moisture will migrate down and out the drain holes. The holes are not plugged at all. I don't know but I doubt natural wool was very common when you were doing vans. In my opinion it's a superior product and easier for a DIY person to work with. It's great to understand how all the systems work together. Be well and stop back my friend.
On the other hand I don't give a damn about family's vacation vans. I like to see the homeless have a place to live and thrive in.
@vivalaleta - that’s a thought for sure.
Your thumbnail says best van insulation and why. Pure clickbait. You basically said trust me, I did my research and picked Havelock wool without presenting any fact based why. Wool is a valid consideration, but it's one of many and there are tradeoffs to all of them. This felt more like an infomercial and is very disappointing. Opinion is not useful when attempting to evaluate the different insulation options on the market.
Hi Chris - thanks for watching and taking the time to comment - I really appreciate your thoughts. I'm sorry you found the advertised point of the video misleading - That was never the intention but with your help I can see how it would happen. I have changed the thumbnail. All my videos are completely my opinion. There has never been affiliate links or sponsors - Not selling anything - ) I'm simply sharing my thoughts as completely as I can - (even the stuff I've invented). Insulation is one of the areas there is great debate between van builders. My feeling is that many people think that because you're insulating you can eliminate the moisture in the wall. I don't believe that's possible, and because of that I believe natural wool is the only practical solution - which is what I tried to communicate in the video. But it's all just my opinion and as I'm often reminded here at home, my opinion and $ 1.50 will get you a coffee at McDonalds. If you are inclined I'd invite you to watch this comparison of D.I.Y. wiring and a store bought power system from Bluetti. th-cam.com/video/5Lzgq2LlGTA/w-d-xo.html I hope you'll stop back. Be well .
@@VanOfAction We all have our opinions which are formed by our own personal ratio of knowledge, ignorance, and starting bias. Where things get questionable and fuzzy is when they start to be represented as facts or knowledge overstated. Sadly TH-cam rewards clickbait titles with things like 'best xxx' titles, and our culture rewards hyperbole when selling things. Channel creators are selling themselves as 'experts' or often shilling products/services for others.
As someone trying to learn it can be hard to sift through tons of videos to find a few golden nuggets of useful information.
I did like your installation tips on installing wool and the importance of keeping it in place so it can be covered and held in place before it get damaged or falls off. Best wishes with your channel.
@@VanOfAction I think that you did a great job explaining your reasoning on why you've chose to use wool for insulating. There is some some things that just happen to be common sense or our own conclusions based on experiences we've had through-out life with the history of usage. Although you are certainly not old, by any means, your graying hair tells me that you've been around for a minute and I'm pretty sure that you have learned a thing or two about a thing or two, lol. One being that no matter what you do or say, you just cannot please everyone. ANYHOO, I myself have been in the process of renovating a travel trailer and have unfortunatly found mold. So my husband and I have been trying to decide what type of insulation we should use & because I have a few thousand pounds of jumbo chunky wool, ( I make those beautiful jumbo chunky blankets that you see being sold on Etsy or instructional videos here on YT on how to arm knit one) we've strongly discussed doing so, SO..... THANK YOU for sharing your video. I don't believe that we've come across a video yet that has discussed or talked about using wool for insulation. Was happy to have finally found one & I'll be SUBBING plus leaving a THUMBS-UP. OH, and of course, we'll be looking forward to viewing more of your videos. Take Care and KEEP SMILING! a new subb and fan, CHERI from SLC, UTAH~
@@cherigibsontrujillo2610 Hi Cheri. Wow thanks for the kind words but more importantly thanks for reading the comments ! That’s awesome. I think you’re right, if you have access to natural wool that is your best bet. When I started I thought I was insulating for heat retention and to help keep the van cool on hot days. But experience has shown me that there simply isn’t enough insulation to be effective with either. The greatest benefit (which may not be as important in a trailer) is the sound proofing the insulation provides. That part is amazing. BUT - With so little insulation - condensation is going to be a reality. Managing it is critical. And allowing air to move (the system to breath) - or the condensation to drain is the secret. I would suggest you plan for both those things. Mold will occur when moisture is allowed to sit against a material such as wood which is an easy place for mold to grow. So just plan for it. Thanks too for your generous opinion about how decrepit I am. I didn’t reply immediately because we’re on the “Great 2023 Road Trip”. Which took us through Utah about a week ago. On our way to Santa Fe. We camped at Willard Bay State Park which was nice (right beside the highway). And I have to tell you I would never have imagined how beautiful Utah is. We were blown away……… be well and let me know how you make out.
@@VanOfAction I sure will. Actually, we've thought about hanging some beautifully made & thick as hell blankets on a few walls and some gorgeous cow hyde rugs too. Maybe even on the ceilings....? It's like falling into a hole when going over all the information & listening to others' experiences with their insulation of choice. We are honestly stuck and haven't a dang clue as to what we are going to use. WHAT A MESS, lol. Anyhow, how fantastic to hear you enjoyed it Here in Utah. I live in a lovely city called Sandy, which is 15 mins south of downtown Salt Lake. It's kind of near the prison, well maybe 20n mins or so northeast. We r right down the street from the REAL soccer stadium. They are a fairly new team and have a beautiful soccer field, just happy that we got some sort of sporting since we'll never have football bcuz the Mormons, lol. Well, you take care n have lots of fun on your trip. And remember to ALWAYS BE SAFE OUT THERE! It's so fantastic to have heard from you. SAFE TRAVELS~ your Utah fan, CHERI 😋 👍 ❤
excellent video, thanks
