Former insulator here. It is good stuff. We only installed it to meet certain fire codes, usually in commercial buildings. I would say around 90 percent of all homes being built still use fiberglass batts in the walls and blown in the attic though, they don't want to pay for the extra cost up front despite the obvious benefits.
I installed RockWool Safe-n-Sound in the partition walls when I remodeled my basement in 2012. I was adding a bedroom for my father-in-law and he's a super light sleeper - very sensitive to all sounds. His room is now the only place in the house where he gets decent sleep. The stuff works, and the added benefit of fire resistance is great for some extra peace of mind. Glad to see some videos to expand the knowledge of these products.
This channel would be so much more valuable if Matt would take more seriously conflicts of interest. He could get this video sponsored by a roof shingle manufacturer or something. I have to be skeptical of nearly everything he says on this channel, which now that I mention it, makes me wonder why I sub at all.
@@kostasg7109 Any link to this and what do you mean "not allowed indoors", like not covered with drywall or something similar?

Civil Engineering from Denmark here. If you didn’t know Rockwool is a Danish company. Doing my work and studies, Rockwool is all we talk about. As a science nerd I aspire to work for Rockwool, not just because they make nice insulation but also because they might have the best R&D department in the country. Meaning, they have so many nice products. Good luck with the build.
As a commercial construction worker I'm extremely familiar with rockwool. It's an excellent product not nearly as dangerous as something either fiberglass or cotton-based or paper based. I constantly had engineers in Florida asking repetitively for it. And I was happy when they did

@@rekostarr7149 well .fibreglass isn't bad for you anymore but neither is rockwool. Fibreglass is super itchy to me rockwool isn't. Both products only produce nuisance dust. An fyi from a ten year insulator and now ten year safety specialist.
I've got rockwool insulation in my garage as of a week ago and you aren't kidding one bit Matt, the sound dampening out there almost keeps up with the 1 foot thick SIPs in my house...its just ridiculous! You do a bang up job pushing construction tech and info out to the masses, so cheers to that bud! Best of luck with with the rest of the house and thanks for taking us along for the ride too.
I used rockwool when I was building out my office. Ripped out a bunch of walls and had to replace the pink fiberglass batts. The rockwool is substantially less itchy than the fiberglass, at least in my experience. The sound deadening seems much better too.
@@CrzBonKerz21 Same and I think most people get placebo effect from it.. Independent studies show that Fiberglass and Rockwool have the same STC rating which in a typical wall is around 1 STC (which is not noticeable to the human ear)..
@@FJB2020 All depends on density of product ranging from glass fiber, polyester and mineral. All have different purposes ie, thermal rated, acoustic rated or FRR etc - generally speaking mineral fiber (rockwool) is a much denser product compared to your conventional fiberglass or polyester. Price range of material goes from fiberglass > polyester > mineral wool. You get what you pay for.
I found rockwool is much less itchy that glass wool. It also has no binders so it is fireproof. It can also be spray filled into the cavities. Foil faced plasterboard gives a more than good enough vapour barrier.
When renovating our 1800s era home I used the safe and sound by Rockwool for the stairwell in addition to fire rated drywall as it being our only means of escape from the second floor in the event of a fire. I figured it was pretty cheap insurance as an extra layer! I also appreciated the rigidity of the product when installing in the basement crawlspace under the foyer.
Just did my entire house in rockwool. I live in the High Desert of Southern California, where it's 115° in the Summer and snows in the winter. Its like living in a ice chest. The insulation properties and sound deadening is insane. Definitely worth the extra money. Probably the best thing I did in my remodel especially considering the price of utilities nowadays.
I like the comparison of different Rockwool products and it is the tip of the iceberg. Their marketing tends to say, "use this here" but not always explain why. CavityRock vs. ComfortBatt? TopRock vs. Rockboard? Roxul Safe vs. CurtainRock? What challenge were the engineers solving when they developed each product, and what changes did they make to solve it? Hoping we can take advantage of your inside access to Rockwool and get some of these nitty gritty details! Thank you for all the content
Just got finished putting the R15 RW batts in my shop building, and my wife said she cant even hear my planer or tablesaw outside. It was also incredibly easy to install. I used an electric bread knife to make all my cuts, which worked way better than I expected.
When I did the siding replacement on my house, I used Rockwool and was very pleased with the results. My house was a 1950s with no standard spacing in the studs, no insulation, no sheathing, and no vapor barrier. Previous owners spent a lot of time making the inside look nice and I didn't want to redo all the drywall to insulate, so I redid the siding ( it was masonite) and went with smooth Hardie plank.
We had loose rockwool insulation in the ceiling of the house I grew up in, and it was definitely superior to anything else IMO. And if I live long enough to actually have a desire to remodel the house I live in, rockwool would be my first choice bar none. Thank you for extolling rockwool's many virtues.
Yup! That’s it I had it!! I’m ripping my walls out and replacing my standard pink installation with rock wool🤣. Been debating and watching videos on here for a few weeks now and this video persuaded me. Thank you for educating us viewers! I wanna turn my bedroom into half studio and half bedroom and I think imma give that Rock wool a try. Oh ! And I’ll probably incorporate it in any future builds like you have your whole entire house. Thank you!
Reason why your contractor is trying to changing your mind, more then likely they’re getting some kind of incentive from manufacturer/supplier or both. More often that’s not passed onto you as the owner.
he even says they allowed him the freedom to use other types of insulation thats why 5% of his house is other insulation dont use rockwool the contractor is right but dont use what the contractor wants do your on reserch this guy says hes sponsor by rockwool and been sponsor so if he shows anyone else he brakes his contract
Rockwool is one of my top building material picks because the batt density is so consistent and they cut like cake. As you can see, the fit and finish of the installed product is excellent. Worth the extra cost!

Having worked in residential, commercial, and industrial construction over 26 years, I paid attention to industry standards. I did my homework, and I learned about what products are best for fire rating, sound dampening, and R-value. This insulation is the only insulation I would use when renovating my own house. There is no way I would ever want foam panel insulation or spray foam anywhere near my project. I've been watching videos on how to install this insulation on the exterior of a house, and I found the videos interesting. Thank you for the video, I always appreciate other perspectives as it helps me to learn something I might have missed on my own; or it affirms my own thoughts about certain products. Have a great rest of your day.
LSL studs are cheaper than dimensional lumber in Northern Colorado. I will never go back... they are a bit harder to work with but they are perfectly straight.
I have a 120 year old Victorian house. I used Rockwool. Fire mitigation is a real thing in these old girls. Soundproofing and ease-of-use, especially with an electric fillet knife. Cost kind of sucks, but buy once - cry once.
i'm installing rockwool in my house as well but my wife is fighting me every step of the way just because of the price..I just know this will be the best choice for sound insulation throughout the house. thanks for this video and keep up the good work :-)
My parents house is also nearly 100% Rockwool and that was 24 years ago in Canada. I have done a couple remodels to my house and where possible I pulled out the fiberglass and replaced with Rockwool. I am a 100% supporter of Rockwool
Check out the "Bahco PC-22-INS Insulation Saw ", we used Rockwool in our garage and in many other areas we have remodeled. That saw makes it super easy to cut and stays sharp. Been through hundreds of pieces and cuts like butter still.
Rockwool is awesome - I'm just a homeowner that found it at the big orange box store. I installed it in my basement ceiling (garage in basement), and I'm now replacing my attic insulation with it. I always recommend it to anyone that talks about insulation.
I'm also sure the installers loved to install rockwool in your house, especially safe and sound, they made a great paycheck 😀👍. Water permeability is also a big key for rockwool vs fiberglass.
I haven't used the Safe and Sound, but have used the R15 on our exterior walls (replacing very old R7 pink stuff) and can attest that the sound difference is incredible, before it was very easy to hear a car pulling up in our gravel driveway, now we hear nothing unless windows are open! Also important to me, as you mentioned, is the vapor permeability, we live in a climate that has extremely humid summers and cold winters, our 40+ year old house (with no vapor barrier) still has the original T1-11 siding (except where porches were improperly done and allowed actual water in) because of that ability to dry from either side. Our goal with remodeling this house is to get it through the next 40+ years with little to no issues.
I don't think that's true but I'd certainly be interested in seeing. I don't see how anyone could make the argument that sound would travel through two layers of drywall plus rockwool easier than only rock wool. But I could be wrong. Drywall itself is a pretty decent sound barrier (not as much as RW) and esp if you get a larger size (5/8 not 1/2 inch).
P.S. Perhaps sounds WITHIN the room would sound a little louder with drywall since the sound would bounce off the drywall easier than the RW but for sounds outside the room..... yeah I think the DW would only enhance the sound deadening. And I think most people are worried about exterior noise (e.g. TV in another room, loud kids, power tools, etc.)
@@user-nh3gu1ge3d sound bounces off and travels around drywall so with the doors open the sound would travel farther than no drywall. its why low sound rooms have the triangle foam exposed as opposed to behind a flat wall
I've used this in three studios that I've built so far. They're so quiet that I can hear my ears ringing. The drywall does bounce some sound off. But the sound stays within that room and doesn't really travel through the walls and or ceiling.
I used Rock Wool throughout the rebuild of the downstairs 950 sq ft apartment in our 50's built 2x6 frame house. It was back to foundation/studs. 2x6 Rockwool in studs above foundation to second floor. New interior 2x4 framing for interior walls with 2 inch offset from foundation and exterior 2x6 walls. 2x4 apartment walls facing exterior Rockwool insulated with 2x4 exterior, all interior facing walls insulated with 2x4 safe and sound, 1st to second floor beams filled two layers of safe and sound along with rezbar and 5/8 drywall. All gap areas fire stopped including wall transitions and fireplace areas. Finished with poly and acoustic sealant vapor seal.... my wife and I lived in this space for 8 months after the build was complete. It was the most comfortable space I have ever lived in through so many weather conditions. It was awesome. Do it right!
I do like it. I was in commercial construction for many years. Many projects were speced out Rockwool way back then. I am thinking about building a cabin and think I will use this product. Thanks Matt.
Hey Matt could you talk about how you being sponsored by Rockwool doesn’t make you biased about any product!? I’m getting mixed reviews on multiple youtube builders/contractors about many products!
I used Roxul sound & safe too, at a small fortune. It would be interesting to see a demo on the 2xs catching fire, and how much if any the rockwool helps as a block to stop spreading to the next stud bay
If you really want to see it, there are other video's (not by Matt) that show side by side, Fiberglass, Rock Wool, open cell foam, and closed cell foam. While the foams will give better temperature insulation, they burn like crazy. Closed cell foam, at least and most likely all of the foam products, will also give off some really nasty chemicals which will dramatically reduce the likelihood of escaping a fire. As a former firefighter, even I was amazed at how fast they burned. Meanwhile, the fiberglass and Rock Wool did not burn. For the fiberglass, the paper backing burned, but the fiberglass, being glass won't burn unless you get up to the glass melting temperature. If you get close to the glass melting temperature, it may get a little gooey. As an example, in today's house fires, fire fighters are seeing temperatures starting around 400 degrees up to 1500 degrees. At a house fire I talked to fire fighters about, their FLIR camera read 742 degrees looking down the hall towards a group of bedrooms that were well involved. The Rock Wool did not ignite at all. You could barely tell where the torch was. Only a small amount of char was seen between the shelves with the Fiberglass and Rock Wool, where the Foams allowed almost complete burn up of the shelves. The example structure was an inexpensive wooden bookshelf as the tester discovered building a new wall as he had planned, was very expensive.
Used Rockwood on our covid home Reno and it has been great and the quietness before putting up the drywall was unbelievable, just like the mike test here.
My father started installing rockwool in remodeling in the early 60s. I've seen it made from rock slag. I've installed it in hundreds of houses. Walls, attics, floors, etc. It is great sfuff.
“Today I’m going to tell you why I went with Rockwell insulation” “this video is sponsored by Rockwell” it’s was free and I got paid to tell you about it, that’s why. 😂😂
Great video. The sound dampening in Rockwool is excellent. I can't believe anyone uses fiberglass batts anymore when there are better products that not only absorb more noise, but are also fire retardant.
Hey Matt, Something I've wondered about is using conduit for running wires what is the negatives on doing this? I figured it might be really helpful to make things future friendly for upgrades.
with what im hearing about the spray foam insulation, i don't want to mess with it, makes me want to stay with fiberglass, and now rock wool is a valid option
I watched a rockwool vs fiberglass video and I was sold on rockwool. I'm doing a addition plus a remodel on the older side of my home. WOW what a difference the rockwool made on the older side of the home. It killed the heat and noise I live in Hawaii where the older construction was poorly done. I'd tell everyone to insulate with rockwool. My AC loves it. I can use a smaller size AC due to the insulation.
Biggest downside for me is almost all residential mineral wool is made with formaldehyde binders. Rockwool does make one version without added-formaldehyde for the commercial market, but it is very difficult to source - as of a few years ago was told it wasn't available west of Chicago. I'd use standard mineral wool in roofs and as exterior insulation, but not in living spaces. Sure wish they'd eliminate formaldehyde like the fiberglass insulation makers did decades ago...
Rockwool states that the high temp cure drives off nearly all of the formaldehyde. This tracks with formaldehyde's decomposition into methanol and carbon monoxide under heat. I'd love to know what rockwool's cure temp and duration are though.
@@AdmiralBob yeah that’s a good point. Most people don’t know when they turn their gas stove on, formaldehyde is an intermediate chemical created and burned during the combustion reaction of natural gas.
RW is going into my house when it gets built at the ranch. Already decided that from a previous video you did on the fire resistance but the sound deadening is the bomb too.
Thanks for the information. I'm going to be building a house this summer and wanting good insulation. I am going to use rigid foam on the outward surface with fiberglass bats on the inward section. After seeing this video, I may be trying something new. I wanted to go with SIP construction but was unable to get a complete bid. First was just quoted for walls. When I told them I wanted the roof to be SIP I was only quoted for over the house/living area of the house but not over the garage. When I requested for the entire roof to be SIP I never heard back. I also wanted a bid for assembly/installation. I called. He was out of the office to be at his child's track meet. I left him a voicemail and sent an email. A week had gone by. Still nothing! Emailed a local contractor to get an estimate for stick framing our house. Next day he contacted me wanting specs so he could work on the numbers. Next day I had an estimate emailed to me. He asked who was doing the foundation, who was doing the driveway, asking if I was needing more than just the house framed up. Next day I had him out to the property for an estimate. The day after I had separate estimates for driveway, foundation, framing, and plumbing and electric. So I decided against SIP even though it would probably save me money in the long run. I'm just going to be very thorough with my insulation. Funny how one person's sluggishness can lead to someone else's opportunity.
Appreciate you putting this video out. Matt really needs to EDUCATE all other builders out there that seem to believe fiberglass is just as good as rockwool. This is a far superior product than any fiberglass product made and wish building codes would start requiring use of this product. Much more beneficial characteristics and had some serious mold/mildew issues in the past from use of fiberglass insulation.
Great video - thank you! I have some questions about using RockWool for exterior insulation. I am leery of using ridged foam for exterior insulation in fire country and have thought RockWool's ComfortBoard 80 and RockWool Roofing Insulation would be better options in areas prone to fire. I would love to hear you discuss this issue and the pros and cons to the options. - Thanks!
I would prefer Rockwool for the qualities mentioned. As for the Formaldehyde content, it appears that the substance breaks down in sunlight and moisture readily. So, a fogging mister, followed by using paint curing lamps, and venting, may be the best neutralizer. The other timber products have formaldehyde in them as well that may be treated simultaneously.
Your videos are so good and accurate and precise, I appreciate it from someone that builds and invents this is great information. Great job well done rockwool is amazing!
Matt, I see that you use Rockwell for your house but other construction projects you use spray insulation. I'm a little confused. Could you explain the pros/cons of each?
If this wasn’t a sponsored video, the host would say that paying double for Rockwool is not justified by it’s benefits. It is more fire and moisture retardant, but is essentially the same in regards to insulating and sound dampening.
Stay tuned Sean. I'm going to make an unsponsored video and justify paying double for Rockwool. Granted I still use high density fiberglass when clients do not see the value of a $1000 upgrade to Rockwool. But I prefer Rockwool, and a $1000 is a great deal for a product that performs better. RESNET Grade 1 is easier to achieve.
I've used this in three music studios that I've built so far. It's amazing. No, I didn't get sponsored. But it would've been nice! I will definitely use it again even if I'm not. Huge difference using it.
I use to use Rockwool for my hydroponic medium, so I can tell you for sure that it will hold water if it can get inside. It's very very absorbent. But dang it looks like a good option.
Yep, it'll hold water just like fiberglass if it's allowed to get wet. The medium itself may not hold water, but surface tension lets water stick to fiberglass and rockwool.
@@boobacockaa Mineral wool insulation is hydrophobic, Matt did not lie. Take a piece, pour water on it, put it in a bucket of water, etc, it will not absorb any water. Hydroponic Rockwool, ie Groden, contains less than 10% Rockwool. It’s a manufactured product primarily containing organic nutrients for plants, air space and the Rockwool is the structure.
I did a crawl space dirt basement with this stuff and it sucked as far as itchy I don't think I've ever worked with a product that will make you more itchy. However, once installed it was nice and you could tell a big difference in the place with the first floor being much warmer. I would recommend a good n-95 mask or better and a full suit or fully clothed.
Great information, and you actually answered a question of mine regarding insulation in the interior walls. Now I have a home built about the 1940's in Deep South Texas so your information has been a great guidance.Your videos have been a tremendous help, especially with much of the work being DIY since I don't have the finances to pay contractors and their workers. But in the same note the savings in labor is allowing me to install better quality material. Thank you for sharing your experience and trade knowledge with others to better understand build, but also provide direction and confidence in DIY projects, thank you.
You will get the same results using Fiberglass.. Understand that matt is basically a sales man for whatever product he is getting for free.. (Do not trust what he says)
@@LackeysLack True, but I can no longer trust his judgment if he only says 'This is the one to buy, trust me, oh and this video sponsored by the same product I am telling you to get'...
Any chance of doing a episode of what all you did to the house would cost a normal person not getting free stuff and what the estimate of the house is ? Just wanted to know how much someone would lose if they wanted to sell
There is these places called Home Depot, Lowes, Menards, and many others, where you can go and find out how much they sell building materials for. It's pretty neat. Then you can call subcontractors and asks how much they charge to build with or install those materials. Then you'll know.
@@mcintosh.daughter what's that have to do with how much he put into the house and what it books for , I don't know everything he bought or what house values around him are
I’m always hesitant to talk costs. This country varies so much with labor rates and even material costs. That being said this house retail would run about $350-400/ft to build today in Austin TX
Guys instaling our used roofing nails, drove them almost all the way in, placed rockwool in, strung up thin wire and around each nail and only after the room was done, drove the nails all the way in to secure wires.
How does Rockwool safe and sound compare to Owen Corning's Thermafiber fire and sound guard, I only ask cause Home Depot does not seem to carry Rockwool
It is very similar, I believe that the density is the same, and both are 3” instead of 3.5 like an R15 batt (so that the 2 pieces of sheet rock are decoupled, ie the insulation isn’t in contact with both pieces of sheet rock). Gas flow resistance is different, but unless you are acoustically treating recoding spaces, that should not make a difference. Also I believe that the R value of sad n sound is roughly R11, just FYI.
Yesterday, 4/26 ... Myself 66 and younger brother 56 did 30 bags of blown in fiberglass insulation. Took about 5 hours or so. I wore a dust mask, didn't need goggles. Also used a breathable cheep painters jumpsuit. Whole house including above garage is R60!!
I use it as well in my house. I've lived thru 2 or 3 fires in a NYC tenement apt, it wasn't good. Plus I'm afraid of lightening strikes too, seen too many houses go up in flames. Whatever I can do to slow down a fire or the flames, I will. Life is worth more than $20 extra a batt.
4:35 I am knife aficionado, and i must say: That was for sure a serrated bread knife that has been sharpened with a standard belt sander, therefore making it standard again. Rockwool being rock destroys the knife bevel , so you need to sharpen frequently
If it is used for isolation (sheathing - insulation - interior drywall/wood covering), fiberglass is going to perform equally as well in terms of dampening resonance. If you are going to build a traditional wall assembly and then in front (interior) fabricate fabric covered stud spaces for acoustic purposes, a safe n sound product will be fantastic. If you are planning on recording instruments, once you reach a depth of about 10”, R30 fiberglass is more effective (due to gas flow resistance) and less expensive. In terms of Isolation you will want to focus on mass, a double leaf system, air sealing, mass, and insulation to dampen resonance.
Remember when asbestos, a rock product, was a miracle material that was superior to everything? Wow, we really thought the world of asbestos and all its benefits
@@cornholy69 the studio is 2x8 construction. Using the Safe&Sound with the FabricMate or Fabric-Wall track with different color material and printed to finish it off. The Zip system is going on now and everything is getting sealed up. I'm just interested in what other "experienced" professionals are doing and not just the "youtube" kids show with foam square bats.
dude I love your videos you’re so informative and your presentation is perfect. I’m sold on the rockwool for the insulation choice of my van that I just purchased.
@@gadenhertog Yes it is a good project... I just finished an insulation project and rockwool was my first choice, but was seriously price prohibitive. Just no way to justify it.
I used it my house addition a few years ago. Paid about $30 per bag, but today I’m working on my garage and find it’s almost $70! Like every else, the price doubled… The dust will make you sick and itchy. Need to use full face mask especially for ceilings, where also it tends to fall. My understanding is that the sound dampening version has same R value. The difference is that one edge is not as flexible for tighter fit. It doesn’t stop sound though…it just stops echo…once drywall is installed, there isn’t much difference. I’d still recommend it, though money would be better spent doubling drywall to block sound…only thing that stops sound is weight and mass coupled with air gaps.
@@ae1ae2 anything is better than rockwool because rockwool drops a lot of particles into the air and it gets into the eyes and lungs even when installed and especially if on the ceiling. I hated working with it. also if you get a bad batch that has been exposed in the rain it will just crumble on you. I brought them to the dump and went with good old fashion fiberglass and it has been cheap and clean. the pros of rockwool are just not worth it. rockwool resist moisture and fire (and PS. negligible more r value) but those things are useless since you can control these things using other methods if you are even slightly knowledgeable.
Also a big fan of rockwool, I have 200mm under my ground floor and 100mm between the floors. In the UK there are 45kg and 60kg products the heaver one is better for sounds but cost more.
Just went through such a nightmare with rockwool, talk to me after you hang your sheetrock. Rockwool was all proud and bellied out the sheetrock everywhere. seems like if they shrunk it down a bit it would have worked great
Hey Matt Risinger, I’m turning a 12x 32 shed to a tiny house for my son. There’s on a small attic… Can you give me some ideas as far as insulation and moisture control? Since there’s not really an attic, would it need foam baffles?
I just installed a couple of thousand square feet of Rockwool insulation. I love it. But have to say that there is definitely shards and dust flying around during cutting and installation. You should absolutely wear a mask.
I'm a big fan of your work, but I got to say I'm really disappointed in your insulation choice. Of course rockwool is a great product, with many great properties. But you've published many videos praising the open cell spray foam product. You were so effusive that I chose open cell spray foam my my house build. I thought I was using the best product that was endorsed by Matt Risinger. So when I see that on your own build that you went with something else, I feel I was suckered.
Will be using Rockwool and QR “dyrwall” for a new master bedroom & bathroom remodel coming up. Like the products and work well, along with ease of use from the products themselves 👍🏻
Former insulator here. It is good stuff. We only installed it to meet certain fire codes, usually in commercial buildings. I would say around 90 percent of all homes being built still use fiberglass batts in the walls and blown in the attic though, they don't want to pay for the extra cost up front despite the obvious benefits.
Obvious benefits would be to live underground. Natural geothermal energy efficiency and no UV radiation 🤣🤣
If I start a home building company I’d use rock wool on every exterior wall and roof area.
@@TheRealWadeW Radeon could be an issue, depending on the area you build your cave.
I installed RockWool Safe-n-Sound in the partition walls when I remodeled my basement in 2012. I was adding a bedroom for my father-in-law and he's a super light sleeper - very sensitive to all sounds. His room is now the only place in the house where he gets decent sleep. The stuff works, and the added benefit of fire resistance is great for some extra peace of mind. Glad to see some videos to expand the knowledge of these products.

I used rockwool when I was building out my office. Ripped out a bunch of walls and had to replace the pink fiberglass batts. The rockwool is substantially less itchy than the fiberglass, at least in my experience. The sound deadening seems much better too.
Sound dampening is a must
I find rockwool worse than normal fiberglass
@@CrzBonKerz21 Same and I think most people get placebo effect from it.. Independent studies show that Fiberglass and Rockwool have the same STC rating which in a typical wall is around 1 STC (which is not noticeable to the human ear)..
@@FJB2020 All depends on density of product ranging from glass fiber, polyester and mineral. All have different purposes ie, thermal rated, acoustic rated or FRR etc - generally speaking mineral fiber (rockwool) is a much denser product compared to your conventional fiberglass or polyester. Price range of material goes from fiberglass > polyester > mineral wool. You get what you pay for.
I found rockwool is much less itchy that glass wool. It also has no binders so it is fireproof.
It can also be spray filled into the cavities. Foil faced plasterboard gives a more than good enough vapour barrier.
When renovating our 1800s era home I used the safe and sound by Rockwool for the stairwell in addition to fire rated drywall as it being our only means of escape from the second floor in the event of a fire. I figured it was pretty cheap insurance as an extra layer! I also appreciated the rigidity of the product when installing in the basement crawlspace under the foyer.
Just did my entire house in rockwool. I live in the High Desert of Southern California, where it's 115° in the Summer and snows in the winter. Its like living in a ice chest. The insulation properties and sound deadening is insane. Definitely worth the extra money. Probably the best thing I did in my remodel especially considering the price of utilities nowadays.
How thick are your walls, please ?
I like the comparison of different Rockwool products and it is the tip of the iceberg. Their marketing tends to say, "use this here" but not always explain why. CavityRock vs. ComfortBatt? TopRock vs. Rockboard? Roxul Safe vs. CurtainRock? What challenge were the engineers solving when they developed each product, and what changes did they make to solve it? Hoping we can take advantage of your inside access to Rockwool and get some of these nitty gritty details! Thank you for all the content
I would also like to know.
Great questions. Are none of these answered on the website?
Just got finished putting the R15 RW batts in my shop building, and my wife said she cant even hear my planer or tablesaw outside. It was also incredibly easy to install. I used an electric bread knife to make all my cuts, which worked way better than I expected.
When I did the siding replacement on my house, I used Rockwool and was very pleased with the results. My house was a 1950s with no standard spacing in the studs, no insulation, no sheathing, and no vapor barrier. Previous owners spent a lot of time making the inside look nice and I didn't want to redo all the drywall to insulate, so I redid the siding ( it was masonite) and went with smooth Hardie plank.
How much did that run ya?
@@Jekyll_Island_Creatures I don't even remember now. It was a while ago.

@@angellas.1314 I really didn't get the chance to really find out. Shortly after doing the work, I took a job in a different city and had to move.
How did you put vapor barrier? I have 1900 house was planing to do the same but not sure how to add vapor barriers
We had loose rockwool insulation in the ceiling of the house I grew up in, and it was definitely superior to anything else IMO. And if I live long enough to actually have a desire to remodel the house I live in, rockwool would be my first choice bar none. Thank you for extolling rockwool's many virtues.
Your opinion is correct i always felt the itch with JOHNS MANVILLE and not Rockwool.....
Yup! That’s it I had it!! I’m ripping my walls out and replacing my standard pink installation with rock wool🤣. Been debating and watching videos on here for a few weeks now and this video persuaded me. Thank you for educating us viewers! I wanna turn my bedroom into half studio and half bedroom and I think imma give that Rock wool a try. Oh ! And I’ll probably incorporate it in any future builds like you have your whole entire house.
Thank you!
You've had me sold on Rockwool even though my contractor is trying to change my mind.
Reason why your contractor is trying to changing your mind, more then likely they’re getting some kind of incentive from manufacturer/supplier or both. More often that’s not passed onto you as the owner.
@@ABC-oo4vm yes because this video being sponsored by rockwool has no bearing on his opinion i am sure.
Just tell them you know Matt Risinger, and ask for the sponsorship discount ;)
@@CookieManCookies when hogs grow wings, just then it still a maybe.
he even says they allowed him the freedom to use other types of insulation thats why 5% of his house is other insulation dont use rockwool the contractor is right but dont use what the contractor wants do your on reserch this guy says hes sponsor by rockwool and been sponsor so if he shows anyone else he brakes his contract
Rockwool is one of my top building material picks because the batt density is so consistent and they cut like cake. As you can see, the fit and finish of the installed product is excellent. Worth the extra cost!
This channel has so much useful information per minute... it is hard to compare. Great source of into!

Having worked in residential, commercial, and industrial construction over 26 years, I paid attention to industry standards. I did my homework, and I learned about what products are best for fire rating, sound dampening, and R-value. This insulation is the only insulation I would use when renovating my own house. There is no way I would ever want foam panel insulation or spray foam anywhere near my project. I've been watching videos on how to install this insulation on the exterior of a house, and I found the videos interesting. Thank you for the video, I always appreciate other perspectives as it helps me to learn something I might have missed on my own; or it affirms my own thoughts about certain products. Have a great rest of your day.
Those studs looks so nice...almost a shame to drywall over.
I notice the same too!
LSL studs are cheaper than dimensional lumber in Northern Colorado. I will never go back... they are a bit harder to work with but they are perfectly straight.
I have a 120 year old Victorian house. I used Rockwool. Fire mitigation is a real thing in these old girls. Soundproofing and ease-of-use, especially with an electric fillet knife. Cost kind of sucks, but buy once - cry once.
awesome idea for cutting!!!
Buy once cry twice and you'll usually come out enjoying your purchases. Research is key lol
i'm installing rockwool in my house as well but my wife is fighting me every step of the way just because of the price..I just know this will be the best choice for sound insulation throughout the house.
thanks for this video and keep up the good work :-)
My parents house is also nearly 100% Rockwool and that was 24 years ago in Canada. I have done a couple remodels to my house and where possible I pulled out the fiberglass and replaced with Rockwool. I am a 100% supporter of Rockwool
Check out the "Bahco PC-22-INS Insulation Saw
", we used Rockwool in our garage and in many other areas we have remodeled. That saw makes it super easy to cut and stays sharp. Been through hundreds of pieces and cuts like butter still.
I use a $9 harbor freight 10 In. Japanese Style saw.. works great.
Dollar store serrated kitchen knife works beautifully.
Rockwool is awesome - I'm just a homeowner that found it at the big orange box store. I installed it in my basement ceiling (garage in basement), and I'm now replacing my attic insulation with it. I always recommend it to anyone that talks about insulation.
Has it cut down on heat loss from the house? I’m planning on this next week!
I'm also sure the installers loved to install rockwool in your house, especially safe and sound, they made a great paycheck 😀👍. Water permeability is also a big key for rockwool vs fiberglass.
I haven't used the Safe and Sound, but have used the R15 on our exterior walls (replacing very old R7 pink stuff) and can attest that the sound difference is incredible, before it was very easy to hear a car pulling up in our gravel driveway, now we hear nothing unless windows are open! Also important to me, as you mentioned, is the vapor permeability, we live in a climate that has extremely humid summers and cold winters, our 40+ year old house (with no vapor barrier) still has the original T1-11 siding (except where porches were improperly done and allowed actual water in) because of that ability to dry from either side. Our goal with remodeling this house is to get it through the next 40+ years with little to no issues.
Did you install a vapor barrier when installing rockwool on an exterior wall ?
please do the sound test again after drywall, since the exposed rockwool will dampen sound much more when exposed
I don't think that's true but I'd certainly be interested in seeing. I don't see how anyone could make the argument that sound would travel through two layers of drywall plus rockwool easier than only rock wool. But I could be wrong. Drywall itself is a pretty decent sound barrier (not as much as RW) and esp if you get a larger size (5/8 not 1/2 inch).
P.S. Perhaps sounds WITHIN the room would sound a little louder with drywall since the sound would bounce off the drywall easier than the RW but for sounds outside the room..... yeah I think the DW would only enhance the sound deadening. And I think most people are worried about exterior noise (e.g. TV in another room, loud kids, power tools, etc.)
@@user-nh3gu1ge3d sound bounces off and travels around drywall so with the doors open the sound would travel farther than no drywall. its why low sound rooms have the triangle foam exposed as opposed to behind a flat wall
I've used this in three studios that I've built so far. They're so quiet that I can hear my ears ringing. The drywall does bounce some sound off. But the sound stays within that room and doesn't really travel through the walls and or ceiling.
Of course the walls will echo with drywall installed but you shouldn't hear much of what's on the other side of the rockwool.
I used Rock Wool throughout the rebuild of the downstairs 950 sq ft apartment in our 50's built 2x6 frame house. It was back to foundation/studs. 2x6 Rockwool in studs above foundation to second floor. New interior 2x4 framing for interior walls with 2 inch offset from foundation and exterior 2x6 walls. 2x4 apartment walls facing exterior Rockwool insulated with 2x4 exterior, all interior facing walls insulated with 2x4 safe and sound, 1st to second floor beams filled two layers of safe and sound along with rezbar and 5/8 drywall. All gap areas fire stopped including wall transitions and fireplace areas. Finished with poly and acoustic sealant vapor seal.... my wife and I lived in this space for 8 months after the build was complete. It was the most comfortable space I have ever lived in through so many weather conditions. It was awesome. Do it right!
I love rockwool, it’s a superior product for sure
I do like it. I was in commercial construction for many years. Many projects were speced out Rockwool way back then. I am thinking about building a cabin and think I will use this product. Thanks Matt.
Hey Matt could you talk about how you being sponsored by Rockwool doesn’t make you biased about any product!?
I’m getting mixed reviews on multiple youtube builders/contractors about many products!
Even if he is sponsord by Rockwell I doubt he would have his whole house covered in it if it was rubbish.
I've been installing Rockwool on my projects over the last few years. I have to say it is a superior product.
I used Roxul sound & safe too, at a small fortune. It would be interesting to see a demo on the 2xs catching fire, and how much if any the rockwool helps as a block to stop spreading to the next stud bay
If you really want to see it, there are other video's (not by Matt) that show side by side, Fiberglass, Rock Wool, open cell foam, and closed cell foam. While the foams will give better temperature insulation, they burn like crazy. Closed cell foam, at least and most likely all of the foam products, will also give off some really nasty chemicals which will dramatically reduce the likelihood of escaping a fire. As a former firefighter, even I was amazed at how fast they burned. Meanwhile, the fiberglass and Rock Wool did not burn. For the fiberglass, the paper backing burned, but the fiberglass, being glass won't burn unless you get up to the glass melting temperature. If you get close to the glass melting temperature, it may get a little gooey. As an example, in today's house fires, fire fighters are seeing temperatures starting around 400 degrees up to 1500 degrees. At a house fire I talked to fire fighters about, their FLIR camera read 742 degrees looking down the hall towards a group of bedrooms that were well involved. The Rock Wool did not ignite at all. You could barely tell where the torch was. Only a small amount of char was seen between the shelves with the Fiberglass and Rock Wool, where the Foams allowed almost complete burn up of the shelves. The example structure was an inexpensive wooden bookshelf as the tester discovered building a new wall as he had planned, was very expensive.
Used Rockwood on our covid home Reno and it has been great and the quietness before putting up the drywall was unbelievable, just like the mike test here.
My father started installing rockwool in remodeling in the early 60s. I've seen it made from rock slag. I've installed it in hundreds of houses. Walls, attics, floors, etc.
It is great sfuff.
I am so stoked for your house. The sound attenuation by itself has me mesmerized.
I’m feeling really blessed. It’s an amazing home
I did my house in rockwool the one thing to keep in mind that dramatic sound attenuation will be reduced once sheetrock is up
Just cover your walls in velvet
Big fan of Rockwool, use it on every project I can. My local lumber yard said they are 150 days out on rockwool orders currently.
“Today I’m going to tell you why I went with Rockwell insulation” “this video is sponsored by Rockwell” it’s was free and I got paid to tell you about it, that’s why. 😂😂

Great video. The sound dampening in Rockwool is excellent. I can't believe anyone uses fiberglass batts anymore when there are better products that not only absorb more noise, but are also fire retardant.
Hey Matt,
Something I've wondered about is using conduit for running wires what is the negatives on doing this? I figured it might be really helpful to make things future friendly for upgrades.
Finally a builder who insulates the interior walls! This is super common outside of the U.S.
The reason was given at 0:30
Yeah, but nonetheless RockWool is the superior product.
😂 you aren't wrong
@@Recovering_Californian It may be a good product, but we got a sales pitch and not an unbiased opinion.
Yup lol
@@Ethan7s Do you find the information he provided misleading or untruthful. If you do, what batt insulation would you recommend instead?
with what im hearing about the spray foam insulation, i don't want to mess with it, makes me want to stay with fiberglass, and now rock wool is a valid option
I watched a rockwool vs fiberglass video and I was sold on rockwool. I'm doing a addition plus a remodel on the older side of my home. WOW what a difference the rockwool made on the older side of the home. It killed the heat and noise I live in Hawaii where the older construction was poorly done. I'd tell everyone to insulate with rockwool. My AC loves it. I can use a smaller size AC due to the insulation.
Biggest downside for me is almost all residential mineral wool is made with formaldehyde binders. Rockwool does make one version without added-formaldehyde for the commercial market, but it is very difficult to source - as of a few years ago was told it wasn't available west of Chicago. I'd use standard mineral wool in roofs and as exterior insulation, but not in living spaces. Sure wish they'd eliminate formaldehyde like the fiberglass insulation makers did decades ago...
Formaldehyde binders was exact reason why I switched to using Johns Manville over Owens Corning for remodel work. Itch difference was huge as well.
Wow good to know that one
Rockwool states that the high temp cure drives off nearly all of the formaldehyde. This tracks with formaldehyde's decomposition into methanol and carbon monoxide under heat. I'd love to know what rockwool's cure temp and duration are though.
@@AdmiralBob yeah that’s a good point. Most people don’t know when they turn their gas stove on, formaldehyde is an intermediate chemical created and burned during the combustion reaction of natural gas.
I love this stuff. I use it in recording rooms and to fill acoustic panels and it’s superb.
Hopefully Rockwool hooked you up. I tried to order it for a house and they were 1 month out.
They totally did!
I had to drive a couple cities over, but I wanted some sound deadening for my interior walls. Everywhere closer wasn't carrying Rockwool.
RW is going into my house when it gets built at the ranch. Already decided that from a previous video you did on the fire resistance but the sound deadening is the bomb too.
Thanks for the information. I'm going to be building a house this summer and wanting good insulation. I am going to use rigid foam on the outward surface with fiberglass bats on the inward section. After seeing this video, I may be trying something new. I wanted to go with SIP construction but was unable to get a complete bid. First was just quoted for walls. When I told them I wanted the roof to be SIP I was only quoted for over the house/living area of the house but not over the garage. When I requested for the entire roof to be SIP I never heard back. I also wanted a bid for assembly/installation. I called. He was out of the office to be at his child's track meet. I left him a voicemail and sent an email. A week had gone by. Still nothing! Emailed a local contractor to get an estimate for stick framing our house. Next day he contacted me wanting specs so he could work on the numbers. Next day I had an estimate emailed to me. He asked who was doing the foundation, who was doing the driveway, asking if I was needing more than just the house framed up. Next day I had him out to the property for an estimate. The day after I had separate estimates for driveway, foundation, framing, and plumbing and electric. So I decided against SIP even though it would probably save me money in the long run. I'm just going to be very thorough with my insulation. Funny how one person's sluggishness can lead to someone else's opportunity.
Appreciate you putting this video out. Matt really needs to EDUCATE all other builders out there that seem to believe fiberglass is just as good as rockwool. This is a far superior product than any fiberglass product made and wish building codes would start requiring use of this product. Much more beneficial characteristics and had some serious mold/mildew issues in the past from use of fiberglass insulation.
With a house that quite you might consider a intercom system for emergency
Mora 7350 Insulation knife is absolute perfect for cutting Rockwool.
Great video - thank you! I have some questions about using RockWool for exterior insulation. I am leery of using ridged foam for exterior insulation in fire country and have thought RockWool's ComfortBoard 80 and RockWool Roofing Insulation would be better options in areas prone to fire. I would love to hear you discuss this issue and the pros and cons to the options. - Thanks!
Thank you for the great video. I like that you were upfront about the sponsorship, but it felt that you were still very objective in your assessment.
I would prefer Rockwool for the qualities mentioned. As for the Formaldehyde content, it appears that the substance breaks down in sunlight and moisture readily. So, a fogging mister, followed by using paint curing lamps, and venting, may be the best neutralizer. The other timber products have formaldehyde in them as well that may be treated simultaneously.
I grew up in Austin, it’s a beautiful city. If I still lived there I would hire you for sure. I use rock wool to grow plants in my hydro system.
Your videos are so good and accurate and precise, I appreciate it from someone that builds and invents this is great information. Great job well done rockwool is amazing!
Matt, I see that you use Rockwell for your house but other construction projects you use spray insulation. I'm a little confused. Could you explain the pros/cons of each?
Mineral wool is great that's all you need to know!
Spray foam is quick and easy to install in a variety of areas.
This stuff looks awesome!
If this wasn’t a sponsored video, the host would say that paying double for Rockwool is not justified by it’s benefits. It is more fire and moisture retardant, but is essentially the same in regards to insulating and sound dampening.
Stay tuned Sean. I'm going to make an unsponsored video and justify paying double for Rockwool. Granted I still use high density fiberglass when clients do not see the value of a $1000 upgrade to Rockwool. But I prefer Rockwool, and a $1000 is a great deal for a product that performs better. RESNET Grade 1 is easier to achieve.
@@mcintosh.daughter “Upgrade”?
I've used this in three music studios that I've built so far. It's amazing. No, I didn't get sponsored. But it would've been nice! I will definitely use it again even if I'm not. Huge difference using it.
Great video - super informative/ helpful. Also - that drone shot of your black metal roof..? Wow - B-E-A- YOOtiful!!
I use to use Rockwool for my hydroponic medium, so I can tell you for sure that it will hold water if it can get inside. It's very very absorbent. But dang it looks like a good option.
Yep, it'll hold water just like fiberglass if it's allowed to get wet. The medium itself may not hold water, but surface tension lets water stick to fiberglass and rockwool.
Yeah, he straight up lied. This stuff 100% absolutely will absorb water. Good product, but he’s full of shit.
I think your thinking of grodan. They make an absorbent version for growing.
@@boobacockaa Mineral wool insulation is hydrophobic, Matt did not lie. Take a piece, pour water on it, put it in a bucket of water, etc, it will not absorb any water.
Hydroponic Rockwool, ie Groden, contains less than 10% Rockwool. It’s a manufactured product primarily containing organic nutrients for plants, air space and the Rockwool is the structure.
I did a crawl space dirt basement with this stuff and it sucked as far as itchy I don't think I've ever worked with a product that will make you more itchy. However, once installed it was nice and you could tell a big difference in the place with the first floor being much warmer. I would recommend a good n-95 mask or better and a full suit or fully clothed.
Your house sounds like a studio with all that insulation around you.
I'd be interested to see the last vacuum test again after the drywall install.
I'd do my house in Rockwool too if they were giving to me to make a vid
It's good stuff. I used it in my lower level remodel. Great for basements and damp areas. One of my better decisions.
I’m still very surprised you didn’t go with closed spray foam on all exterior walls.
It was the one thing I hoped to hear in this video....
Trimming that stuff flush with the studs is a nightmare, and the effective R-value per $ after thermal bridging is awful, even for Matt's projects.
Great information, and you actually answered a question of mine regarding insulation in the interior walls. Now I have a home built about the 1940's in Deep South Texas so your information has been a great guidance.Your videos have been a tremendous help, especially with much of the work being DIY since I don't have the finances to pay contractors and their workers. But in the same note the savings in labor is allowing me to install better quality material. Thank you for sharing your experience and trade knowledge with others to better understand build, but also provide direction and confidence in DIY projects, thank you.

There is these places called Home Depot, Lowes, Menards, and many others, where you can go and find out how much they sell building materials for. It's pretty neat. Then you can call subcontractors and asks how much they charge to build with or install those materials. Then you'll know.

Guys instaling our used roofing nails, drove them almost all the way in, placed rockwool in, strung up thin wire and around each nail and only after the room was done, drove the nails all the way in to secure wires.
I'm using this in the house I'm building next spring, largely for the sound deadening. You see, I'm a very poor musician ...
You could instead purchase complimentary earplugs for the neighbors
In my recording studio, I use acoustic panels that I made out of Safe n Sound. Absolutely fantastic.
I live in WV and I purchased Rock Wool for my house
I built about a dozen safe and sound bats for my studio and home theater. Best thing I ever did. Absorbs sound like a sponge.
How does Rockwool safe and sound compare to Owen Corning's Thermafiber fire and sound guard, I only ask cause Home Depot does not seem to carry Rockwool
Shopping for building materials at Home Depot is your first mistake.
Lowes might have it. I believe Home Depot carries an Owens Corning mineral wool that I assume is basically the same
It is very similar, I believe that the density is the same, and both are 3” instead of 3.5 like an R15 batt (so that the 2 pieces of sheet rock are decoupled, ie the insulation isn’t in contact with both pieces of sheet rock). Gas flow resistance is different, but unless you are acoustically treating recoding spaces, that should not make a difference. Also I believe that the R value of sad n sound is roughly R11, just FYI.
Yesterday, 4/26 ... Myself 66 and younger brother 56 did 30 bags
of blown in fiberglass insulation. Took about 5 hours or so.
I wore a dust mask, didn't need goggles. Also used a breathable
cheep painters jumpsuit. Whole house including above garage is R60!!
I use it as well in my house. I've lived thru 2 or 3 fires in a NYC tenement apt, it wasn't good. Plus I'm afraid of lightening strikes too, seen too many houses go up in flames. Whatever I can do to slow down a fire or the flames, I will. Life is worth more than $20 extra a batt.
4:35 I am knife aficionado, and i must say:
That was for sure a serrated bread knife that has been sharpened with a standard belt sander, therefore making it standard again.
Rockwool being rock destroys the knife bevel , so you need to sharpen frequently
8:02 damn the HVAC did a great job... usually its just straight and in the way of anyone needing to move through that attic.
Matt, do you have a video on your studio with rockwoll and fabric? Looking to put together a studio with the same and Zip.
If it is used for isolation (sheathing - insulation - interior drywall/wood covering), fiberglass is going to perform equally as well in terms of dampening resonance. If you are going to build a traditional wall assembly and then in front (interior) fabricate fabric covered stud spaces for acoustic purposes, a safe n sound product will be fantastic. If you are planning on recording instruments, once you reach a depth of about 10”, R30 fiberglass is more effective (due to gas flow resistance) and less expensive.
In terms of Isolation you will want to focus on mass, a double leaf system, air sealing, mass, and insulation to dampen resonance.
Remember when asbestos, a rock product, was a miracle material that was superior to everything? Wow, we really thought the world of asbestos and all its benefits
@@cornholy69 the studio is 2x8 construction. Using the Safe&Sound with the FabricMate or Fabric-Wall track with different color material and printed to finish it off. The Zip system is going on now and everything is getting sealed up. I'm just interested in what other "experienced" professionals are doing and not just the "youtube" kids show with foam square bats.
dude I love your videos you’re so informative and your presentation is perfect. I’m sold on the rockwool for the insulation choice of my van that I just purchased.
#1 reason... they sponsor my videos and give me free insulation and money to boot.
True
he even says they allowed him the freedom to use other types of insulation but onyl 5% meaning that 5% is what he really wanted
Yup. But it is actually a very good product in my (personal) experience.
@@gadenhertog Yes it is a good project... I just finished an insulation project and rockwool was my first choice, but was seriously price prohibitive. Just no way to justify it.
Did he say anything that was dishonest or untrue. If so, what batt insulation would you recommend?
Excellent demonstration at the end.
Pretty impressive, I will try it on my next project
I used it my house addition a few years ago. Paid about $30 per bag, but today I’m working on my garage and find it’s almost $70! Like every else, the price doubled…
The dust will make you sick and itchy. Need to use full face mask especially for ceilings, where also it tends to fall.
My understanding is that the sound dampening version has same R value. The difference is that one edge is not as flexible for tighter fit. It doesn’t stop sound though…it just stops echo…once drywall is installed, there isn’t much difference. I’d still recommend it, though money would be better spent doubling drywall to block sound…only thing that stops sound is weight and mass coupled with air gaps.
Hello @Matt Risinger do you have a link to the metal strings used to keep the ceiling batts in place? Really great video!

Is there another product you think would be better? If so, what are its pros / cons relative to Rockwool?
@@ae1ae2 anything is better than rockwool because rockwool drops a lot of particles into the air and it gets into the eyes and lungs even when installed and especially if on the ceiling. I hated working with it. also if you get a bad batch that has been exposed in the rain it will just crumble on you. I brought them to the dump and went with good old fashion fiberglass and it has been cheap and clean. the pros of rockwool are just not worth it. rockwool resist moisture and fire (and PS. negligible more r value) but those things are useless since you can control these things using other methods if you are even slightly knowledgeable.
@@rekostarr7149 Very unfortunate. Don't mind me. I'm just a butthead.
Also a big fan of rockwool, I have 200mm under my ground floor and 100mm between the floors. In the UK there are 45kg and 60kg products the heaver one is better for sounds but cost more.
As a commercial general contractor I 100% agree with rockwool
Just went through such a nightmare with rockwool, talk to me after you hang your sheetrock. Rockwool was all proud and bellied out the sheetrock everywhere. seems like if they shrunk it down a bit it would have worked great
Hey Matt Risinger, I’m turning a 12x 32 shed to a tiny house for my son. There’s on a small attic… Can you give me some ideas as far as insulation and moisture control? Since there’s not really an attic, would it need foam baffles?
I just installed a couple of thousand square feet of Rockwool insulation. I love it. But have to say that there is definitely shards and dust flying around during cutting and installation. You should absolutely wear a mask.
I want to build my own caravan, if I do, it will be with Rockwool, mostly for the fire resistens, but you said a few new things I didnt know, great! 😎
Never heard of quiet rock before, looked it up and love it as far as the science goes, likely to use in my basment remodel
I'm a big fan of your work, but I got to say I'm really disappointed in your insulation choice. Of course rockwool is a great product, with many great properties. But you've published many videos praising the open cell spray foam product. You were so effusive that I chose open cell spray foam my my house build. I thought I was using the best product that was endorsed by Matt Risinger. So when I see that on your own build that you went with something else, I feel I was suckered.
Intelligent people do their own research
Love using Rockwool. Thanks for the info.
Even only the acoustic sold me :)
Will be using Rockwool and QR “dyrwall” for a new master bedroom & bathroom remodel coming up.
Like the products and work well, along with ease of use from the products themselves 👍🏻
