@@whymindsetmatters IDK what kind of math and labor costs you are factoring, but I have never once made it pencil out. A typical wall without any siding is right around 3 bucks per wall square foot. That includes dry wall, studs, insulation, and sheathing. 1 square foot of 6 inch thick concrete wall is about $2.70. That is just concrete. That is not the ICF, drywall, or concrete truck. So unless you are paying your carpenters in gold bricks or they work incredibly slow, IDK how you are even coming close.
@@tristanjones7735 I should've been clear. Most people use ICF for below grade basements, not the entire home. Although there are entire homes framed with it?
I built our home 9 years ago with LOGIX ICF's. It was my first use of ICFs and I didn''t pick any easy design. If you're familiar with DELTEC homes, That is what we built. It consists of 17 sides, each 8'. It took me about a week to stack the house. The more conventional attached garage took an afternoon. I built a giant miter box out of plywood to cut the angles on the ICFs as virtually every block of the foundation was cut on a miter.
Steve would be proud of my icf design. I have pango wrap under my footers and basement floor and the transitions on the outside to a rubber sealant that goes up my icf walls and then transitions to sharkskin on the roof. So I can draw a line all the way around my icf home without lifting my pencils for a continuous air barrier. My blower door score should be amazing 😂
We have designed homes with this brand of ICF foundations and then drop a prefab modular unit on top, works great and fast. Cost is irrelevant when you factor everything that goes into building a home. Great system.
In my career I ended up using several different brands of ICF. I finally ended up using Logix and never wanted to use any other after that. They have an extensive product line and after watching this video it appears that they have continued to be innovating. The lock down aspect is huge (no more floating corners or joint separation during placement) in my opinion. I still don’t know if I’m sold on the door/window buck system but it does look more innovative than any I have seen to date.
More people need to build with this product. Why do we use sticks and paper? Everything standing from our past is built with stone and concrete! This is cool
Sustainability being a reason. Also, with proper care (waterproofing, screws, bolts, heavier dimensions for the lumber, like in germany/switzerland/austria/scandinavia) wooden homes can last 100s of years too.
Yo why do white people bring up chicago like it's the only dangerous place in all of America? Yall ever been to a trailer park in Minnesota 😂? All poor neighborhoods in every inch of the globe are extremely violent.... why? Because poverty causes desperation and desperation causes fighting for resources which directly leads to violence which creates a cycle of extremely traumatized and decencitized and mentally ill children that are bound to go down the same path but worse
Do they offer thicker foam for a higher R value? How does it interact with the footings? What does the installation of the utilities inside look like? Can you make a roof from this material?
ICF blocks are great. I think the 16" block height is a little limiting in that wall height only work out evenly in 4' multiples. If you are doing and ICF house from footer to rafter, it is harder to get custom wall heights without cutting blocks. I think a 12" block height would be more flexible in design options. One think not mentioned with ICF construction, is that you get a very air tight house without much effort.
Great points, it's always advantageous from a labour and material standpoint to design to the height of whatever ICF form you're using, but it's even more important to get the end result that yourself or the client wants. Element ICF has convenient embossed cut lines at 4", 8", and 12" to make cutting to those heights quick and easy. Being a fully reversible form the off cuts can be reused. -- Jay from AMC Foam
@@amcfoamtechI was just mentioning to the guy who thought he would like a 12 inch block that it exists. yes you're absolutely correct. I actually prefer the 16 inch height. And ripping one course if necessary takes no time at all. Much faster in my opinion stacking a larger quantity of 12 inch blocks. I have experience with amvic and fox , however the new element block seems to have every feature one can ask for and priced well also. I'll know once I use it but should be a game changer for the industry. I've already contacted my rep and have a project upcoming using element.
We're huge fans of ICF, love Nudura but can see how this line is really giving them a run for the money. One quick point about the Logic Bucks. While plywood/OSB is commonly used to strengthen parts of the block for a pour, in the case with Logix/Element bucks, you simply screw through the foam to fasten them in, no need to strap with wood on the exterior for that product. You will have to have some interior bracing though. If you plan correctly, you can keep some bracing in place to attach a nail flange onto if you're going to recess windows in.
There was some testing a while back that showed inset windows screwed directly into the concrete core provided the strongest seal against wind and rain. No buck needed there too, but some detailing is needed to make sure it slopes correctly and everything.
@@rafflesmaos I'd love to know how that could be done effectively without pre-drilling each tapcon screw.I'd prefer to use some 1" LVL furring strips to attach to.
@@SchondorfEnt Yeah there's not much to do about escaping drilling the concrete, but that's what they've been doing in Europe for a while now. Many of their buildings are concrete and brick, and they mostly use the inset windows. I just happen to really dislike having dead tree carcass in the building envelope, so I'd personally rather pay a bit more towards the extra labor of installing the windows, hehe.
@@rafflesmaos Perhaps, but a fluid applied waterproofed LVL is nothing short of a bomber detail for attaching a window flange to. I hear you, if $ was endless sure
This channel is nothing but ads anymore. I miss the days when you consistently showed construction content. Even the videos you shoot on building sites wind up being ads for products rather than showing high performance building techniques in detail like you use to.
He’s literally showcasing new products and innovations that can and have changed industry standards. Also everyone needs to eat. What’s the problem again?
It’s not carrying water; it’s common sense. And why the “calm down” comment? @dlg5485 had zero snark in his comment unlike you. There’s already too much of that on social media and it’s usually so unnecessary and uncalled for. We’re all learning here hopefully.
No mention of how many feet vertically can be done in s single pour. Is the bracing more or less extensive than wood forms? Is it rented? Which technique ties them down to the footing for the pour? The installer brochure that I received off their website is just that a few pages of product pictures without the details.
Not sure on the max height in one pour, but they typically go one story at a time. You stack a story, put up rental bracing (look up icf bracing), then it's poured in lifts from above, typically 2-3 feet at a time, using either a pump hose or a boom truck. After each lift is poured it's optimally vibrated from the inside with a long pencil concrete vibrator. It continues on with multiple small lifts until the wall is filled. You then run floor joists and decking, stack the next story, brace it and continue. To anchor the wall correctly your footing has be prepared in advance. L shaped rebar called verticals are placed in the footer before the footer pour and they extend out of the footer about 30". There's a document called the prescriptive method of ICF that will tell you vertical spacing and rebar type based on soil type and backfill height of a basement. ICF is easy from a practical perspective but you need to closely follow the engineering tables for wall thickness and rebar requirements below grade and rebar spacing and thickness above grade for wind speeds against the structure and roof loads on lentils. Perfectly doable DIY though, just make sure you obsess over the details, especially rebar reinforcement, water proofing, sleeving all penetrations in advance, pre-inserting L bolts for ledgers, etc.
@@whymindsetmatters Hey there! We actually have three GPS insulation product lines including Chrome GPS (unfaced GPS sheets), HALO rigid insulation including Subterra, Interra, and Exterra (faced GPS for below grade, interior, and exterior applications), and GPS ICF.

Built my 2000 square foot house in 2006 with the entire first floor ICF. Even when it is -25 degrees outside without heating never goes below 37 inside.
Matt I am diy building a 48’ tall 13k sqft multigenerational home. I am currently 37’ above grade. I only have 11’ more to go 🎊. I would love for you to come do an episode on how a person can diy the shell in their spare time. Or send Stephanie down from salt lake. I am only 45 minutes south of her.
Inspired... I am doing the same thing just slightly smaller 9000. I'm DIY too. Even dug my own Sitework. I'm framing my footers as we speak. Would love to connect if you're open to it. I'm in Charlotte SC market. Nice job🎉
I wonder if you could do a spray foam core in some applications (instead of concrete). Could be pretty strong with vertical reinforcement. Super light, all insulation.
We typically recommend 3'-4' lifts. Higher slump concrete mixes or SCC usually requires a slower pour rate or shorter lifts. ICF contractor experience comes into play here, there are some do's and don't's that we help train ICF contractors on in our onsite and online training! -- Jay from AMC Foam
I am building my personal icf home with geothermal heating and cooling and i-span steel floor joist system in colorado. Its 8500sqft interior conditioned space + 250sqft sunroom area + 2400sqft 5-car garage + 1300 sqft under garage tool shop. Its 35' with basement, mainlevel and upper level without roof. So far i am happy with construction part, rest i will know more about efficiency when its enclosed. But i am using nadura icf, seems like element icf picked the nubs and ratcheting system from nadura. Good thing i seen in element icf is you can cut every 4" without cutting the plastic.
This sounds like a great project I use Nudura myself and love it, using geothermal heat pumps is great, based on the size of your project and the technicalities of geothermal, make sure your designer has the best source and calculations are double checked, because that size project and the location of openings will be key, the ICF will be fine, it’s the heating/cooling zones throughout the house that can be tricky to nail
Current plan for my little house (once I find the right location) is to have the basement in ICF and the ground floor in SIP with a nice thick SIP cap of a roof.
Make sure to read the insurance contract first. Because a lot of insurance companies will resfuse to pay out for termite damage if the foundation is made with ICF. seems to be happening more and more .....
Why not do ICF from the footer to the rafter? SIPs have the same issue with ease of renovation as ICFs do. I agree with you on the use of SIP roof panels.
@@tombogaert1015 Curious. Where are the termites coming from? If ICF basement has concrete floor and walls in foam, are they eating the concrete? I have an ICF building and they would have to get to the LVL joists for first bite of wood. Would think the insurance benefit would be other way around. No walls or foundation to mess with to repair.
Real easy i just hot knife in a groove for the electrical and the pluming where I had to penetrate the wall I just put a pvc pipe the wall before the pour.
Did an entire house out of this last year, stacked all of the block myself and dont think I would ever build a house any other way. House is extremely efficient to heat or cool and very quiet. Cost wise not much more than stick built because of all of the labor savings in the walls. Look it over I think you will like it!
Did I just miss the info or can this be coated with something to protect it. I know various types of siding can be attached. What if someone doesn't want typical siding, like an exposed basement wall on a walkout basement?
Great question, ICF construction can be finished with virtually any type of interior or exterior finishes that a lumber or steel framed building can be. Acrylic or cementitious stucco, EIFS, vertical siding, horizontal siding, stone, full brick or thin veneer, panelized systems like ACM, the list goes on... your local ICF manufacturer rep can help you out to find the best way to achieve your desired finish! -- Jay from AMC Foam
I've got a place in NE texas, has a nice hill that I've been thinking of building a 14-16ft tall 40x80/50x100 arena(to catch water for house use), & build a 2story house under the arena on one end w/a deck that sticks out,&shop on bottom. I want the house in-between the 2 post on the end so concrete wall on bottom floor. The house end of hill drops 15ft so w/a 2 story I can help prevent erosion on path from house. Slight downhill from shop would be better. Hilly area of Texas & there are dirt terraces on each road/path. Would this foam work against dirt/What would you put on the foam to run water off&down(house will be mostly protected by arena from water)? I've thot about wood foundation as road/path wouldn't carry a concrete truck at the moment. I know they use wood foundations in Minnesota & out of the way places that can't get a concrete truck into. Concrete wall could actually be away from house 5ft or 2 walls(5&10ft away), & use top of wall(s)(&ground outside for supporting 2nd&3rd story deck(s)).....I'm only explaining plans for a small part of the 106 acres(2-3 rows of pecans n&s along sw border, rows of grapes/muscadines, southside of hill planted in coastal or native grasses so to keep miles of view south clear, north side of hill is more vertical-plant different colored crepe myrtles for view from road&secret meandering path down hill w/water falls(one huge one or several down to a pond that is already built(above gulley-i think they built it as they were mining for clay f/road terraces), etc. So many ideas! I'm looking for suggestions & if you want to make a video of the place/hill/progress, great. Thx!
@LogixBrands thx. This 106 acre place is amazing. Spring west to east between road&hill with slow gulley(thinking several lined squared ponds feeding each other-can use pump to recirculate) w/2-3acre pond at bottom just above wwc, wet weather creek along n/s along east boundary for pumped water to ponds&irrigation f/pecans, great views north&east&south&sw, several pond sites(thinking 50-60ft drop from deck into pond would be great place for a zipline). I want to keep the hill view(3story w/one&half stories cut into hill with deck(s) for views. I'm always searching for ideas. The arena/large roof actually, for water&solar(?) would actually be hidden 300yds from road by pines except for end&house&decks. Want a office/study up high for view(study'study'study :) Jump off deck outside of study&living room for zipline. I have a fb page for the place but won't post unless asked. Just a bunch of ideas(slowly coming together). House doesn't have to be huge, just tall for views&deck. Thx for your yt vids!
Is the GPS foam also termite resistant? I'll be looking forward to seeing that used for the Element system! Hopefully they'll be out by the time I want to start building my forever home in a year or two.
I have bewen interested in ICF for a while but I was told that areas where termite are a threat to homes ICF is not good to use due to not being able to get termite protection as they have bored into the forms and cant be delt with. As such the termite companies will not insure or guarantee the protection. I would love to get get some feedback on your thoughts regarding termites.
I built a 2 story ICF fully off-grid House 5 years ago using Nudura ICF forms. Almost no difference between this and Nudura. I can't comment on price difference as I bought all my ICF before "Covid19". It's easy to build airtight homes with ICF. You can heat our house of 3000 sq ft with a hair dryer! Well almost. We only have a 3 ton heat pump with an ERV.
They make ICCFs too! It's ICF, except it's made of recycled Styrofoam (from coolers, packing Styrofoam, etc...) so it helps keep those hard-to-recycle plastics out of the landfills while also sometimes using less concrete, which reduces carbon emissions
just finished drying in an ICF house with my dad in Northern Maine. Walkout basement and first floor all ICF. The only issue we're having is finding a 11.5" wide door sill plate.
The biggest shortcoming of this system, of which are few, is addressing termite prevention/detection, a major limitation in termite prone zones. Otherwise, it's an almost incomparable wall sysrem impervious to most natural elements.
Technically hat's not a shortcoming of ICF, in fact termites can't even compromise ICF since the core is concrete. Yes detection can be a problem, but prevention is much the same as anything else. Termite mesh, termite parge coat, chemical spraying, etc. Also eliminating any structural wood internally is also an option (steel joist or concrete floors, etc)
@@rafflesmaos .The complaint that I hear from code officials, rightly or wrongly, is the difficulty in finding any evidence of the mud tunnels used to bridge obstructions that are the classic form of detection. I get that one can pretreat the area with anti-termite treatments, but it's added cost that potentially has a limited life. The new normal today is to install bait traps to know if there is any local insect activity, but the contractors then examine the concrete/blok foudation walls for evidence of tunneling activity. The ICFform buries that inside the wall. I'm beside myself on this because I earnestly believe that ICF construction is the best of breed construction innovation since the use of wood. I'm too old to fully benefit from this technology but, if I were to add room onto my existing house it would use this tech and double it floor and ceiling as a storm shelter.
@@rooscow Yeah I mean realistically there's a number of ways to deal with it. For example Nudura has a treatment they can add to the foam itself, or they have a detail where there's an embedded strip of plywood that can be checked, etc. But even if all protection methods fail, it can only ever be an issue if there's a food source for them inside the building and they manage to tunnel far enough to get to it. So if there's no path through the concrete, they can't get inside for example. If there's no wood structures inside (concrete floors etc), then they can't feed off of anything. And so on.
Termites are easily mitigated with a variety of products; One of which we recommend often, and has been tested for termite prevention is Soprema's Colphene ICF membrane!
About a year ago, yall put out a video with details about the inflation reduction act. I, like you, live in Texas and as far as I know, there is still no way to take advantage of any of those programs. Do you have any idea what the status is on that those programs? It so, would love to see a new video on it!
can someone talk about termites and other insects that would burrow into the EPS or Graphite Polystyrene forms. I have heard that some insurance companies would not insure a house that used ICFs below grade
@@ArnieD17 in the 80's my sister had a basement built with ICFs . The termites burrowed in and eventually made it to the house. not a second hand story. I was just interested to know if ICF bug prevention has improvement.
You barely touched on: 1. how DIY friendly this really is. Wife and I built our own, only contracted the pours, hanging the trusses(crane day), metal roofing and drywall. 2000 sq/ft full daylight basement. It went VERY FAST! 2. How thermally stable the finished house can be with the CC mass putting the inside temp out of phase with the outside temp variations. My house varies perhaps 3 degrees throughout the day using low mass radiant heat(warmboard) and a relatively small boiler. Its the most quiet and comfortable building I have ever stayed in…
Can you get a steadycam, or at least a gimbal for your camera operator? I hate getting seasick in my own bed, watching YT. The segment around 14:30 was terrible for that.
Hey there, we've had GPS (graphite polystyrene) as an available option in our LOGIX ICF line up for many years called LOGIX ICF Platinum series. It will also be available as an option in Element ICF! -- Jay from AMC Foam
I am diy building a 48’ tall ice home and my tools for the walls are a rebar bender/cutter, a foam gun, screw gun, skill saw, drywall saw and of course the bracing. I only have 11’ more to go and I have straight walls 😊
Why would you work to the middle from 2 corners and create a vertical seam? wouldnt working from one corner to another make more sense? keeping the stagger throughout the build?
20 years ago I trimmed an apartment built with ICFs. 6” high maple baseboard that they left stacked Willy-nilly in the garage in the humid summer. Many boards were bowed like mad and the nailers in the icf’s could not hold that maple. Total nightmare. Turned me off icf’s but still planning to use them for my own build.
Are ICF basements a thing? Edit: Matt's past videos on ICF (that I've seen) were about building the external house walls from ICF, which is why I didn't realize that was meant for below grade walls until they mentioned it much later in the video.
They can, though there are products that insert flashing into the blocks to stop termite tunneling. Also, if you don't have any exterior wood near the ground, there is no incentive for them to tunnel through the foam since it is not edible.
I helped my dad build an ICF house 15 years ago. We did hire a group familar with ICF to do most of the form work. ICF sounds easy, but the reality is when you pour concrete - you can blow out walls and spill concrete everywhere when it is not properly supported on both sides. Zero mention of this issue -- as I think it is the number one issue holding back ICF construction.
Hi Jonathan, blow outs are very rare with the correct installation processes. Because of the smaller modular size of ICF forms compared to larger panel forms, when blow outs do occur in ICF construction they are usually significantly smaller than the blow outs that can occur in panel form systems. We offer free online, in-person, and on-site ICF installer training to ensure folks know how to set themselves up for a successful concrete placement! Did you and your Dad have any blow outs on your ICF project? -- Jay from AMC Foam
@@amcfoamtech No, we did not experience a blow out. ICF is great when done right. I just don’t remember at any point in the video where bracing was mentioned or how to brace correctly.
cost and it really is more work than just stacking 'legos' needed items-- bracing, staging for the pour, knowledge/experience, more steel needed , etc.... but the concept does make sense.
I think it’s exposure Because I’ve done many projects with it and it cost about the same when you factor in the smaller crew (labor cost and skilled trades) fewer connections, lighter workload (foam is light and the pump truck does the heavy pour), easier and faster than pour in place, less room for error than framing, bracing isn’t as difficult as pour in place because the 5+ inch of eps makes bracing easier because it’s more about balancing the vertical wall after properly locking in the base to footing, I use a system that is near full-proof Ensuring the top of the wall is plumb, level and straight is the trickiest part, but with the right equipment or skill it can be done That’s the part people screw up the most and it’s very hard to fix or nearly impossible to correct
@@koriifaloju2051 I wish more people would do it, as well as build firms. It was really painful for me to find a contractor experienced with it, and I still have to do a lot of legwork coordinating between the architect, civil and the contractor. Meanwhile companies like toll brothers churn out cookie cutter homes that start falling apart after a few years.
situationally dependent. they have been troublesome for us on one off archi driven customs with embeds, captured joists, moment frame anchoring. we prefer forms and we will gladly waterproof, rigid tape and matrix once the forms are stripped plus we have lots of requests for perfect above ground concrete andvthe transition is a pain.
In building my new house in Florida, I looked seriously at doing ICF. What stopped me was the $10,000 in braces I was either going to have to buy, or go 2 hours to Orlando to rent the braces (also not cheap) and eventually just stayed with block which Huleo and his gang can stack cheaper and quicker.
interesting reasoning... the labor/time involved in laying block, dealing with window/door openings, all the steps needed to insulate it, hassles of running MEP & penetrations, pain with attaching walls/finishes/siding/cabinets/etc, living with all that thermal bridging, and still not have the strength or thermal mass or continuous vapor/airtight envelope? some ICF bracing can even use the sticks you'll re-use for interior walls anyway. paid $2800 for my used bracing, and it'll be sellable for the same once i'm done with it. couple days stacking/bracing, one pour day for FastFoot up to roofline & slab... doesn't get any quicker.
Imagine ICF, but geopolymer concrete with biochar aggregate. Strong, hard shell, thinner than ICF to reduce weight, and net GWP negative. More economical than ICF. R-0.2 to R-0.5. Slightly heavier than ICF, but then ICF seems too light sometimes, liable to blow around the job site on windy days. Biochar concrete is still up to 15% lighter than concrete for the same strength when prefab to hit optimum strength at 55 degrees C (131 F) for 28 hours on the production line. Fill the 6" gap with hempcrete, for equal R-value to ICF, plastic free.
It's only important below grade. Above grade it doesn't really need to be waterproofed as the siding is usually sufficient, but some people do foam compatible spray on waterproofing above grade just in case. EPS doesn't rot like wood, and even retains some insulative properties when wet.
Maximum R Value depends on the given form and manufacturer. There's some forms that allow basically any R value you want. Generally speaking ICF will be far more efficient than stick built, doesn't need any fussy air sealing detailing work, and can be used to build passive as well as net zero houses. It's up to the owner to figure out what R value they want to aim for, then pick a form, keeping in mind that even if a wood wall and ICF wall have the same R Value, ICF will still be better due to the thermal mass involved.
I'm interested in ICF construction but I don't want my house to be made out of fly ash. Could you really trust your contractor to pour concrete made with ordinary portland cement without added fly ash, and for that matter, trust the ready mix company to actually honor the request and deliver it?
I am in Utah and we had 1” hail recently. My home is under construction and it got some dents but did just fine. But yes I will be putting siding on the outside of it when I am done.
You can finish ICF structures with the same weather resilient finishes that you would any other type of building. The difference with ICF is how much more disaster resilient a concrete structure is overall compared to wood, steel, SIP, and many other types of structures... -- Jay from AMC Foam
@@amcfoamtech You forgot the exclamation point at the end of your response! 😂 Just messing with you; I appreciate all the responses you’ve provided to questions. And your enthusiasm!!
all the manufacturers of ICF products say you don't need a vapour barrier. That is incorrect. Ask any ICF manufacturer if you need to waterproof their ICF when used for a basement foundation and every one will say absolutely yes you must waterproof the ICF foundation wall.. ie is is not water tight. Well guys there is the answer.. if the ICF product is not watertight and needs waterproofing, then the ICF is certainly not water vapour tight. Check any of the written instructions for the ICF they all say you need to waterproof it, ie it is not waterproof/water tight.. and as such that means it is certainly not water vapour proof / vapour tight.
Concrete filled block with exterior polystyrene and stucco is a much better system. Insulating the interior space is dumb. You block the advantage of thermal mass and the temperature stability it provides.
I like the general idea of ICF, but I don't like having the foam on the outside of the wall, especially in an area that has a problem with termites or ants as they can make nests inside the foam. I would much rather have a concrete surface on at least the outside of the wall with foam in the center and perhaps the interior side of the wall. Any chance we could see a removable exterior form as part of the site assembled kits?
@@danscott6454 Yeah, I was actually thinking about a wall assembly that had The Perfect Block in the center with 2-3 inches of concrete on either side of the blocks using traditional removable forms with fiberglass form ties so you don't have the thermal bridging of metal form ties. I also like the spider tie system, but I don't know if you can put as much insulation in as I would like, and the lack of information on their website and any recent videos here on TH-cam makes me wonder if they are still in business.
Some of the companies make a bug shield that is inserted between two courses around the perimeter. It's a thin strip of metal that will block the burrowers.
It's actually the other way around, you want concrete to be closer to the inside, because that's where all the thermal mass is. The more thermal mass on the inside, the more comfortable the house will be without wild temperature swings.
This is simply not true! Termites are easily controlled and mitigated with a variety of products. ICF does not contain any organic food materials- So your only threat is pests tunneling the foam not actually feeding from anything. Soprema's Colphene ICF membrane is one of our most recommended product!
Please please please more ICF videos. I am losing my mind!

Still pencils out when you consider the time and labor costs savings.
@@whymindsetmatters IDK what kind of math and labor costs you are factoring, but I have never once made it pencil out. A typical wall without any siding is right around 3 bucks per wall square foot. That includes dry wall, studs, insulation, and sheathing. 1 square foot of 6 inch thick concrete wall is about $2.70. That is just concrete. That is not the ICF, drywall, or concrete truck. So unless you are paying your carpenters in gold bricks or they work incredibly slow, IDK how you are even coming close.

They have an extensive product line and after watching this video it appears that they have continued to be innovating. The lock down aspect is huge (no more floating corners or joint separation during placement) in my opinion.
I still don’t know if I’m sold on the door/window buck system but it does look more innovative than any I have seen to date.
More people need to build with this product. Why do we use sticks and paper? Everything standing from our past is built with stone and concrete! This is cool
The 48’ multigenerational icf home that I am diy building should be in my family for more than 500 years.
Sustainability being a reason. Also, with proper care (waterproofing, screws, bolts, heavier dimensions for the lumber, like in germany/switzerland/austria/scandinavia) wooden homes can last 100s of years too.
Because most builders are framers or work with primarily framers.
Because this is extremely expensive
@@antonnovosselov7762 not true. Saves you money in the longer term actually
It is also bullet proof in case you need to build in Chicago.
Or Baltimore and Philly.
Yo why do white people bring up chicago like it's the only dangerous place in all of America? Yall ever been to a trailer park in Minnesota 😂? All poor neighborhoods in every inch of the globe are extremely violent.... why? Because poverty causes desperation and desperation causes fighting for resources which directly leads to violence which creates a cycle of extremely traumatized and decencitized and mentally ill children that are bound to go down the same path but worse
Yep see some houses build with this system 20y ago back home is great.
Do they offer thicker foam for a higher R value? How does it interact with the footings? What does the installation of the utilities inside look like? Can you make a roof from this material?
ICF blocks are great. I think the 16" block height is a little limiting in that wall height only work out evenly in 4' multiples. If you are doing and ICF house from footer to rafter, it is harder to get custom wall heights without cutting blocks. I think a 12" block height would be more flexible in design options. One think not mentioned with ICF construction, is that you get a very air tight house without much effort.
Superform has 12 inch blocks
Great points, it's always advantageous from a labour and material standpoint to design to the height of whatever ICF form you're using, but it's even more important to get the end result that yourself or the client wants. Element ICF has convenient embossed cut lines at 4", 8", and 12" to make cutting to those heights quick and easy. Being a fully reversible form the off cuts can be reused. -- Jay from AMC Foam
@@amcfoamtechI was just mentioning to the guy who thought he would like a 12 inch block that it exists. yes you're absolutely correct. I actually prefer the 16 inch height. And ripping one course if necessary takes no time at all. Much faster in my opinion stacking a larger quantity of 12 inch blocks. I have experience with amvic and fox , however the new element block seems to have every feature one can ask for and priced well also. I'll know once I use it but should be a game changer for the industry. I've already contacted my rep and have a project upcoming using element.
I am diy building a 48’ tall icf house. Cutting the windows adds some time but it is doable.
@@absolutetorquetuning7956 Awesome! Thank for your that and we look forward to hearing your feedback! -- Jay from AMC Foam
We're huge fans of ICF, love Nudura but can see how this line is really giving them a run for the money. One quick point about the Logic Bucks. While plywood/OSB is commonly used to strengthen parts of the block for a pour, in the case with Logix/Element bucks, you simply screw through the foam to fasten them in, no need to strap with wood on the exterior for that product. You will have to have some interior bracing though. If you plan correctly, you can keep some bracing in place to attach a nail flange onto if you're going to recess windows in.
There was some testing a while back that showed inset windows screwed directly into the concrete core provided the strongest seal against wind and rain. No buck needed there too, but some detailing is needed to make sure it slopes correctly and everything.
@@rafflesmaos I'd love to know how that could be done effectively without pre-drilling each tapcon screw.I'd prefer to use some 1" LVL furring strips to attach to.
@@SchondorfEnt Yeah there's not much to do about escaping drilling the concrete, but that's what they've been doing in Europe for a while now. Many of their buildings are concrete and brick, and they mostly use the inset windows.
I just happen to really dislike having dead tree carcass in the building envelope, so I'd personally rather pay a bit more towards the extra labor of installing the windows, hehe.
@@rafflesmaos Perhaps, but a fluid applied waterproofed LVL is nothing short of a bomber detail for attaching a window flange to. I hear you, if $ was endless sure
DO they offer forms for the footer? what does that connection look like with or without an ICF form for the footer

It’s not carrying water; it’s common sense. And why the “calm down” comment? @dlg5485 had zero snark in his comment unlike you. There’s already too much of that on social media and it’s usually so unnecessary and uncalled for. We’re all learning here hopefully.
@@dlg5485 People building new homes like to know about new home building products, it's crazy...
Heard about these back in 2008. (Canada).
No mention of how many feet vertically can be done in s single pour. Is the bracing more or less extensive than wood forms? Is it rented? Which technique ties them down to the footing for the pour? The installer brochure that I received off their website is just that a few pages of product pictures without the details.
Not sure on the max height in one pour, but they typically go one story at a time. You stack a story, put up rental bracing (look up icf bracing), then it's poured in lifts from above, typically 2-3 feet at a time, using either a pump hose or a boom truck. After each lift is poured it's optimally vibrated from the inside with a long pencil concrete vibrator. It continues on with multiple small lifts until the wall is filled. You then run floor joists and decking, stack the next story, brace it and continue. To anchor the wall correctly your footing has be prepared in advance. L shaped rebar called verticals are placed in the footer before the footer pour and they extend out of the footer about 30". There's a document called the prescriptive method of ICF that will tell you vertical spacing and rebar type based on soil type and backfill height of a basement. ICF is easy from a practical perspective but you need to closely follow the engineering tables for wall thickness and rebar requirements below grade and rebar spacing and thickness above grade for wind speeds against the structure and roof loads on lentils. Perfectly doable DIY though, just make sure you obsess over the details, especially rebar reinforcement, water proofing, sleeving all penetrations in advance, pre-inserting L bolts for ledgers, etc.

I wonder if you could do a spray foam core in some applications (instead of concrete). Could be pretty strong with vertical reinforcement. Super light, all insulation.
Do you have to do 2ft lifts as you go up?
We typically recommend 3'-4' lifts. Higher slump concrete mixes or SCC usually requires a slower pour rate or shorter lifts. ICF contractor experience comes into play here, there are some do's and don't's that we help train ICF contractors on in our onsite and online training! -- Jay from AMC Foam
@amcfoamtech thanks Jay. Looking at using them for my cash wash project.
I am building my personal icf home with geothermal heating and cooling and i-span steel floor joist system in colorado. Its 8500sqft interior conditioned space + 250sqft sunroom area + 2400sqft 5-car garage + 1300 sqft under garage tool shop. Its 35' with basement, mainlevel and upper level without roof.
So far i am happy with construction part, rest i will know more about efficiency when its enclosed. But i am using nadura icf, seems like element icf picked the nubs and ratcheting system from nadura. Good thing i seen in element icf is you can cut every 4" without cutting the plastic.
U a po' man isn't u!? Who the fck needs an 8500 sf home, no one!!
This sounds like a great project
I use Nudura myself and love it, using geothermal heat pumps is great, based on the size of your project and the technicalities of geothermal, make sure your designer has the best source and calculations are double checked, because that size project and the location of openings will be key, the ICF will be fine, it’s the heating/cooling zones throughout the house that can be tricky to nail
Current plan for my little house (once I find the right location) is to have the basement in ICF and the ground floor in SIP with a nice thick SIP cap of a roof.
Make sure to read the insurance contract first. Because a lot of insurance companies will resfuse to pay out for termite damage if the foundation is made with ICF. seems to be happening more and more .....
Why not do ICF from the footer to the rafter? SIPs have the same issue with ease of renovation as ICFs do. I agree with you on the use of SIP roof panels.
@@tombogaert1015 Curious. Where are the termites coming from? If ICF basement has concrete floor and walls in foam, are they eating the concrete? I have an ICF building and they would have to get to the LVL joists for first bite of wood. Would think the insurance benefit would be other way around. No walls or foundation to mess with to repair.
@@tombogaert1015not true regarding termites. If an issue there are barriers that can be installed.
@@bwillanno reason not to go ICFs from footer to rafter. SIPs are not faster to installor more energy efficient than ICFs.
What is your view on ICF vs Superior Wall for a walkout basement?
Matt,
Can you please look at the Vegas based firm offering geopolymer concrete formulations? Have they done any residential projects yet?
Looks flammable
EPS will not catch fire or produce a flame. ICF has a 4 hour fire rating!
@@LogixBrands is that because of the concert or the product
would like to see how to run electrical or plumbing through these walls
Real easy i just hot knife in a groove for the electrical and the pluming where I had to penetrate the wall I just put a pvc pipe the wall before the pour.
Did an entire house out of this last year, stacked all of the block myself and dont think I would ever build a house any other way. House is extremely efficient to heat or cool and very quiet. Cost wise not much more than stick built because of all of the labor savings in the walls. Look it over I think you will like it!
Did I just miss the info or can this be coated with something to protect it. I know various types of siding can be attached. What if someone doesn't want typical siding, like an exposed basement wall on a walkout basement?
Most ICF makers offer brick ledges.
Great question, ICF construction can be finished with virtually any type of interior or exterior finishes that a lumber or steel framed building can be. Acrylic or cementitious stucco, EIFS, vertical siding, horizontal siding, stone, full brick or thin veneer, panelized systems like ACM, the list goes on... your local ICF manufacturer rep can help you out to find the best way to achieve your desired finish! -- Jay from AMC Foam
I've got a place in NE texas, has a nice hill that I've been thinking of building a 14-16ft tall 40x80/50x100 arena(to catch water for house use), & build a 2story house under the arena on one end w/a deck that sticks out,&shop on bottom. I want the house in-between the 2 post on the end so concrete wall on bottom floor. The house end of hill drops 15ft so w/a 2 story I can help prevent erosion on path from house. Slight downhill from shop would be better. Hilly area of Texas & there are dirt terraces on each road/path.
Would this foam work against dirt/What would you put on the foam to run water off&down(house will be mostly protected by arena from water)?
I've thot about wood foundation as road/path wouldn't carry a concrete truck at the moment. I know they use wood foundations in Minnesota & out of the way places that can't get a concrete truck into. Concrete wall could actually be away from house 5ft or 2 walls(5&10ft away), & use top of wall(s)(&ground outside for supporting 2nd&3rd story deck(s)).....I'm only explaining plans for a small part of the 106 acres(2-3 rows of pecans n&s along sw border, rows of grapes/muscadines, southside of hill planted in coastal or native grasses so to keep miles of view south clear, north side of hill is more vertical-plant different colored crepe myrtles for view from road&secret meandering path down hill w/water falls(one huge one or several down to a pond that is already built(above gulley-i think they built it as they were mining for clay f/road terraces), etc. So many ideas!
I'm looking for suggestions & if you want to make a video of the place/hill/progress, great.
Thx!
Check out ICF waterproofing membranes! We often recommend peel-n-stick products over a spray application.
@LogixBrands thx. This 106 acre place is amazing. Spring west to east between road&hill with slow gulley(thinking several lined squared ponds feeding each other-can use pump to recirculate) w/2-3acre pond at bottom just above wwc, wet weather creek along n/s along east boundary for pumped water to ponds&irrigation f/pecans, great views north&east&south&sw, several pond sites(thinking 50-60ft drop from deck into pond would be great place for a zipline). I want to keep the hill view(3story w/one&half stories cut into hill with deck(s) for views. I'm always searching for ideas. The arena/large roof actually, for water&solar(?) would actually be hidden 300yds from road by pines except for end&house&decks. Want a office/study up high for view(study'study'study :) Jump off deck outside of study&living room for zipline. I have a fb page for the place but won't post unless asked. Just a bunch of ideas(slowly coming together). House doesn't have to be huge, just tall for views&deck.
Thx for your yt vids!
Is the GPS foam also termite resistant? I'll be looking forward to seeing that used for the Element system! Hopefully they'll be out by the time I want to start building my forever home in a year or two.
No got to protect it somehow
@@IronrodpowerThe other ICF manufacturers that make a gray version claim their gray version is termite resistant.
There's termite sprays and layers you can add to it if needed. Same if you want to waterproof it
I have bewen interested in ICF for a while but I was told that areas where termite are a threat to homes ICF is not good to use due to not being able to get termite protection as they have bored into the forms and cant be delt with. As such the termite companies will not insure or guarantee the protection. I would love to get get some feedback on your thoughts regarding termites.
FYI The patent for ICF was officially submitted in Canada on March 22, 1966, and the U.S. patent application granted October 24, 1968.
I built a 2 story ICF fully off-grid House 5 years ago using Nudura ICF forms. Almost no difference between this and Nudura. I can't comment on price difference as I bought all my ICF before "Covid19". It's easy to build airtight homes with ICF. You can heat our house of 3000 sq ft with a hair dryer! Well almost. We only have a 3 ton heat pump with an ERV.
Great product. Helpful video. What's with the sloppy camera work? Very annoying.
How do you handle the footer?
What have they done about the termite issues with the ICF’s below grade
Theres termite membranes you can use
They make ICCFs too! It's ICF, except it's made of recycled Styrofoam (from coolers, packing Styrofoam, etc...) so it helps keep those hard-to-recycle plastics out of the landfills while also sometimes using less concrete, which reduces carbon emissions
just finished drying in an ICF house with my dad in Northern Maine. Walkout basement and first floor all ICF. The only issue we're having is finding a 11.5" wide door sill plate.
I’d be interested to hear if you’ve found a solution.
@juliatrainer2633 not yet. It's closed up for the winter and we'll get back to work in the spring
The biggest shortcoming of this system, of which are few, is addressing termite prevention/detection, a major limitation in termite prone zones. Otherwise, it's an almost incomparable wall sysrem impervious to most natural elements.
Technically hat's not a shortcoming of ICF, in fact termites can't even compromise ICF since the core is concrete. Yes detection can be a problem, but prevention is much the same as anything else. Termite mesh, termite parge coat, chemical spraying, etc. Also eliminating any structural wood internally is also an option (steel joist or concrete floors, etc)
@@rafflesmaos .The complaint that I hear from code officials, rightly or wrongly, is the difficulty in finding any evidence of the mud tunnels used to bridge obstructions that are the classic form of detection. I get that one can pretreat the area with anti-termite treatments, but it's added cost that potentially has a limited life. The new normal today is to install bait traps to know if there is any local insect activity, but the contractors then examine the concrete/blok foudation walls for evidence of tunneling activity. The ICFform buries that inside the wall. I'm beside myself on this because I earnestly believe that ICF construction is the best of breed construction innovation since the use of wood. I'm too old to fully benefit from this technology but, if I were to add room onto my existing house it would use this tech and double it floor and ceiling as a storm shelter.
@@rooscow Yeah I mean realistically there's a number of ways to deal with it. For example Nudura has a treatment they can add to the foam itself, or they have a detail where there's an embedded strip of plywood that can be checked, etc.
But even if all protection methods fail, it can only ever be an issue if there's a food source for them inside the building and they manage to tunnel far enough to get to it. So if there's no path through the concrete, they can't get inside for example. If there's no wood structures inside (concrete floors etc), then they can't feed off of anything. And so on.
Termites are easily mitigated with a variety of products; One of which we recommend often, and has been tested for termite prevention is Soprema's Colphene ICF membrane!
About a year ago, yall put out a video with details about the inflation reduction act. I, like you, live in Texas and as far as I know, there is still no way to take advantage of any of those programs. Do you have any idea what the status is on that those programs? It so, would love to see a new video on it!
Earthquake concern. don't the ties interfere with rebar fencing?
The ties are what hold the rebar in place, you’d lay a course, then seat and tie the rebar, and repeat
ICF's are very resilient to earthquakes, tornados, hurricanes and any natural disaster!
can someone talk about termites and other insects that would burrow into the EPS or Graphite Polystyrene forms. I have heard that some insurance companies would not insure a house that used ICFs below grade

You barely touched on: 1. how DIY friendly this really is. Wife and I built our own, only contracted the pours, hanging the trusses(crane day), metal roofing and drywall. 2000 sq/ft full daylight basement. It went VERY FAST! 2. How thermally stable the finished house can be with the CC mass putting the inside temp out of phase with the outside temp variations. My house varies perhaps 3 degrees throughout the day using low mass radiant heat(warmboard) and a relatively small boiler. Its the most quiet and comfortable building I have ever stayed in…
Can you get a steadycam, or at least a gimbal for your camera operator? I hate getting seasick in my own bed, watching YT. The segment around 14:30 was terrible for that.

There also should really be a company that offers a panelized icf home kit.
Hey there, we've had GPS (graphite polystyrene) as an available option in our LOGIX ICF line up for many years called LOGIX ICF Platinum series. It will also be available as an option in Element ICF! -- Jay from AMC Foam
@@amcfoamtechWhat is the benefit of GPS over other ICF systems? Over ICCF (e.g. Perfect Block) ?
Nice system but would like radius corners added to their lineup.
last week it was wood foundations , now this! not alot of tools needed only Bracing and more braces ,
I am diy building a 48’ tall ice home and my tools for the walls are a rebar bender/cutter, a foam gun, screw gun, skill saw, drywall saw and of course the bracing.
I only have 11’ more to go and I have straight walls 😊
Why would you work to the middle from 2 corners and create a vertical seam? wouldnt working from one corner to another make more sense? keeping the stagger throughout the build?
20 years ago I trimmed an apartment built with ICFs. 6” high maple baseboard that they left stacked Willy-nilly in the garage in the humid summer. Many boards were bowed like mad and the nailers in the icf’s could not hold that maple. Total nightmare. Turned me off icf’s but still planning to use them for my own build.
Are ICF basements a thing?
Edit: Matt's past videos on ICF (that I've seen) were about building the external house walls from ICF, which is why I didn't realize that was meant for below grade walls until they mentioned it much later in the video.
Will termites eat through the foam?
They can, though there are products that insert flashing into the blocks to stop termite tunneling. Also, if you don't have any exterior wood near the ground, there is no incentive for them to tunnel through the foam since it is not edible.
Check out Sopremas Colphene ICF membrane for termite mitigation!
First one ;)), thanks Matt, keep up with the great content !!!
I helped my dad build an ICF house 15 years ago. We did hire a group familar with ICF to do most of the form work. ICF sounds easy, but the reality is when you pour concrete - you can blow out walls and spill concrete everywhere when it is not properly supported on both sides. Zero mention of this issue -- as I think it is the number one issue holding back ICF construction.
Hi Jonathan, blow outs are very rare with the correct installation processes. Because of the smaller modular size of ICF forms compared to larger panel forms, when blow outs do occur in ICF construction they are usually significantly smaller than the blow outs that can occur in panel form systems. We offer free online, in-person, and on-site ICF installer training to ensure folks know how to set themselves up for a successful concrete placement! Did you and your Dad have any blow outs on your ICF project? -- Jay from AMC Foam
Vibrating helps with this
@@amcfoamtech No, we did not experience a blow out. ICF is great when done right. I just don’t remember at any point in the video where bracing was mentioned or how to brace correctly.
@@naya4607self compacting cement doesn’t need much if any vibration. And using Helix micro rebar to replace some of the rebar helps that even more.
There are so many advantages so it is really hard to understand why so few people build with it.
Some people would rather put up a gaudy gold chandelier than to spend a few extra percent on a better building shell.
cost and it really is more work than just stacking 'legos' needed items-- bracing, staging for the pour, knowledge/experience, more steel needed , etc.... but the concept does make sense.
Cost…
I think it’s exposure
Because I’ve done many projects with it and it cost about the same when you factor in the smaller crew (labor cost and skilled trades) fewer connections, lighter workload (foam is light and the pump truck does the heavy pour), easier and faster than pour in place, less room for error than framing, bracing isn’t as difficult as pour in place because the 5+ inch of eps makes bracing easier because it’s more about balancing the vertical wall after properly locking in the base to footing, I use a system that is near full-proof
Ensuring the top of the wall is plumb, level and straight is the trickiest part, but with the right equipment or skill it can be done
That’s the part people screw up the most and it’s very hard to fix or nearly impossible to correct
@@koriifaloju2051 I wish more people would do it, as well as build firms. It was really painful for me to find a contractor experienced with it, and I still have to do a lot of legwork coordinating between the architect, civil and the contractor. Meanwhile companies like toll brothers churn out cookie cutter homes that start falling apart after a few years.
LMAO "Editors...!!! HELP ME OUT!!!"
situationally dependent. they have been troublesome for us on one off archi driven customs with embeds, captured joists, moment frame anchoring. we prefer forms and we will gladly waterproof, rigid tape and matrix once the forms are stripped plus we have lots of requests for perfect above ground concrete andvthe transition is a pain.
It's not just put them together.
There is bracing that needs to be done correctly or you're destroying everything. Bracing equipment is not cheap
In building my new house in Florida, I looked seriously at doing ICF. What stopped me was the $10,000 in braces I was either going to have to buy, or go 2 hours to Orlando to rent the braces (also not cheap) and eventually just stayed with block which Huleo and his gang can stack cheaper and quicker.
Who is Huleo??
@@naya4607 lol
interesting reasoning... the labor/time involved in laying block, dealing with window/door openings, all the steps needed to insulate it, hassles of running MEP & penetrations, pain with attaching walls/finishes/siding/cabinets/etc, living with all that thermal bridging, and still not have the strength or thermal mass or continuous vapor/airtight envelope?
some ICF bracing can even use the sticks you'll re-use for interior walls anyway. paid $2800 for my used bracing, and it'll be sellable for the same once i'm done with it. couple days stacking/bracing, one pour day for FastFoot up to roofline & slab... doesn't get any quicker.
Holy shakey camera!
Imagine ICF, but geopolymer concrete with biochar aggregate. Strong, hard shell, thinner than ICF to reduce weight, and net GWP negative.
More economical than ICF. R-0.2 to R-0.5. Slightly heavier than ICF, but then ICF seems too light sometimes, liable to blow around the job site on windy days.
Biochar concrete is still up to 15% lighter than concrete for the same strength when prefab to hit optimum strength at 55 degrees C (131 F) for 28 hours on the production line.
Fill the 6" gap with hempcrete, for equal R-value to ICF, plastic free.
If waterproofing is so important why doesn't ICF come will Polycoat waterproofing already attached. Wouldn't that be great. Only have to do touch-ups.
It's only important below grade. Above grade it doesn't really need to be waterproofed as the siding is usually sufficient, but some people do foam compatible spray on waterproofing above grade just in case. EPS doesn't rot like wood, and even retains some insulative properties when wet.
13:01 😂 6:00 8:34 😂 13:47
My question as a layperson is what is the best R value you can get? Is it better with lumber or spray foam?
Maximum R Value depends on the given form and manufacturer. There's some forms that allow basically any R value you want. Generally speaking ICF will be far more efficient than stick built, doesn't need any fussy air sealing detailing work, and can be used to build passive as well as net zero houses. It's up to the owner to figure out what R value they want to aim for, then pick a form, keeping in mind that even if a wood wall and ICF wall have the same R Value, ICF will still be better due to the thermal mass involved.
Footers need embedded vertical rebar, and a 6-inch rubber water stop
Ideally bentonite inlay on a keyway in the concrete footer
Plus it's bulletproof, in case the ATF or the Police comes after your kids and your dogs.
I'm interested in ICF construction but I don't want my house to be made out of fly ash. Could you really trust your contractor to pour concrete made with ordinary portland cement without added fly ash, and for that matter, trust the ready mix company to actually honor the request and deliver it?
How do you run and wiring/plumbing?
Do you put OBS or other sheathing on the outside, or just the siding?
That foam would get ruined by the wind and hail here in CO.
I am in Utah and we had 1” hail recently. My home is under construction and it got some dents but did just fine.
But yes I will be putting siding on the outside of it when I am done.
You can finish ICF structures with the same weather resilient finishes that you would any other type of building. The difference with ICF is how much more disaster resilient a concrete structure is overall compared to wood, steel, SIP, and many other types of structures... -- Jay from AMC Foam

The best review on the new Element block is linked below. This guy really knows ICF.
m.th-cam.com/video/aTp9sAV2rCs/w-d-xo.html
all the manufacturers of ICF products say you don't need a vapour barrier. That is incorrect.
Ask any ICF manufacturer if you need to waterproof their ICF when used for a basement foundation and every one will say absolutely yes you must waterproof the ICF foundation wall.. ie is is not water tight.
Well guys there is the answer.. if the ICF product is not watertight and needs waterproofing, then the ICF is certainly not water vapour tight. Check any of the written instructions for the ICF they all say you need to waterproof it, ie it is not waterproof/water tight.. and as such that means it is certainly not water vapour proof / vapour tight.
Matt, I'd be really interested in hearing your opinion of a different type of ICF called The Perfect Block. Insulated Composite Concrete Forms.
You’ll hear from Matt on The Perfect Block only if they sponsor an episode. Not meant to be a criticism per se, just a fact.
Concrete filled block with exterior polystyrene and stucco is a much better system. Insulating the interior space is dumb. You block the advantage of thermal mass and the temperature stability it provides.
I really can't imagine why you would do anything else.

Your getting this teeth trrrr 😂😂😂
Garrett sounds like Brad Pitt.
Pumicecrete is a far superior building product than ICF
So 30 minute commercial?

I like the general idea of ICF, but I don't like having the foam on the outside of the wall, especially in an area that has a problem with termites or ants as they can make nests inside the foam. I would much rather have a concrete surface on at least the outside of the wall with foam in the center and perhaps the interior side of the wall. Any chance we could see a removable exterior form as part of the site assembled kits?
This is one reason why I’d like to hear Matt’s opinion on The Perfect Block ICCF.
@@danscott6454 Yeah, I was actually thinking about a wall assembly that had The Perfect Block in the center with 2-3 inches of concrete on either side of the blocks using traditional removable forms with fiberglass form ties so you don't have the thermal bridging of metal form ties. I also like the spider tie system, but I don't know if you can put as much insulation in as I would like, and the lack of information on their website and any recent videos here on TH-cam makes me wonder if they are still in business.
Some of the companies make a bug shield that is inserted between two courses around the perimeter. It's a thin strip of metal that will block the burrowers.
@@r.j.bedore9884Steve Basic did a video on perfect block.
It's actually the other way around, you want concrete to be closer to the inside, because that's where all the thermal mass is. The more thermal mass on the inside, the more comfortable the house will be without wild temperature swings.
I am getting seasick of the camera work..
The handheld camera is awful...
Great info but wooooof... video work about gave me motion sickness
Who’s on the camera? Slow down
Many exterminators won't inspect or warranty ICF inspection or even do/touch. Which means you can't get a morgtage or refi for ICF
This is simply not true! Termites are easily controlled and mitigated with a variety of products. ICF does not contain any organic food materials- So your only threat is pests tunneling the foam not actually feeding from anything. Soprema's Colphene ICF membrane is one of our most recommended product!

Matt Your last name is misspelled. What do I win?
can we stop with the camera shake?
but who wants a Styrofoam basement walls? The homeowner HAS to finish the basement with drywall?
Most fire codes require gypsum anyway then you put on what you want for finished wall
@wanderinginminnesota8591 so that's an added expense to be considered in the overall comparison...a huge expense
Shaking camera is too much for my ADHD. punching out
I wanted to throw up with all that camera jerking. why don't you use a gimble camera stabilization device?
