Exterior Insulation w/ Common Materials ft. Scott True

[@mazie.wilson]

I wish Scott could build my house. He truly seems like the type of builder that is giving his all to make these houses the absolute best that they can be within the budget. He also gives off the vibes that if something were to go wrong he would be there instantly to fix the problem without fighting the customer on it

[@baxt1412]

Literally would have no doubts that things are getting done right and staying budget friendly. That would be a dream prize pack even if he could just be involved with planning of my house

[@FlockoftheGreyShepherd]

Nice to see when people really have a passion for what they do. Scott deserves all the success that comes his way.

[@drsg9124]

Watching him makes me really upset at how terrible the general contractor I'm working with is

[@scpitts]

I couldn't agree more and I live in the Dallas-Fort Worth area.

[@TheBuilderdad]

There are a lot of contractors that lack business acumen. Maybe show him these vids and try to help him up his game

[@DA33_718]

Scott reeks of trust ❤. You get a guy like this to build your house and its money well spent 👌

[@buildshow]

Indeed!

[@MegsCarpentry-lovedogs]

@@buildshow Yes indeed. I just mentioned Scott's name and what he practices on exterior insulation and how he deals with penetration to the builder here on Prince Edward Island, Atlantic Canada. Details of air tight are part of the interviewing process with the builders for this air tight build planned for 2025'ish. Matt, your name was mentioned as well as Steve Baczeks and J. Lstiburek. The perfect roof and wall, window sealing and continuity of the outer envelope, rain screen, bug screen....framing details that Steve B. talkes and show in his Boston build show and what you have shown in your vids Matt. The "men" that I interview, as a female, are generally surprised by the building science I understand, as shown in my interviews with them. So, Matt, keep that Scott coming as a regular guest. He is so sincere and genuine and an honest kind of guy....nothing fake about him...Perfect, onnnn The Build Show!☺🇨🇦

[@chrisking6740]

I'm a tile contractor who builds mostly showers. I whole heartedly agree with Scott's philosophy about mixing manufacturers and feeling comfortable with YOUR product. I also use Kerdi on top of my mortar bed shower pans, with FloFx drains, and Hydro Ban or Hydro Barrier with Laticrete reinforcing fabric on all corners and seams. It is a super bomb proof installation and I can say that Scott has nothing to worry about here. Another consideration is that any manufacturer warranty covers THEIR product, and if a shower needs to get ripped out due to a failure, the $1000 in that manufacturers materials is the least of my concerns. Worst case, that's what liability insurance is for. Best case, make sure that never happens.

[@johnwhite2576]

Why not use all laticrete products? They make their own membrane to cover mud base? I get the drain you chose 1st it’s the best tho laticretes not bad . And why even use a mud pan? Use laticretes preformed pans- no need to worry about blocked weep holes you get perfect even slope you save hours of work and mess and of course laticrete in every product category cheaper than Schleuter equivalent as you undoubtedly know …

[@ScottTrue]

@@johnwhite2576 Good points. Sometimes I'm using what's available locally. For the laticrete products, I have to drive to Austin, which I do sometimes.

[@chrisking6740]

@@johnwhite2576 Good questions. I've tried many combinations and systems and this is what I install every time now. Kerdi is slightly thinner and more flexible than HyrdoBan sheet membrane, it lays down nicer on the pan. I use mortar beds over foam pans because I know that no matter the site conditions, shower size and shape, drain placement, subfloor levelness etc, I can install my base that day and it comes out exactly how I want it to every time. Also, mortar bed is money in my pocket, foam pan is money in Schluter's pocket. You are correct about Laticrete being cheaper than Schulter though. I do use all Laticrete thinset.

[@kurtsemlinger6859]

OMG, another amazing home detail review with SCOTT, for the more practical everyday homeowner! Only 1 QUESTION: why not ZIP R-6 sheathing? Is it more expensive than Zip with outside insulation? We definitely need more shows like this... AND we need a Matt & Steve list of builders nationally. I need one in Coastal NC. Cheers, Eric

[@nicholascooper1193]

This is exactly how I wanted to build my exterior walls. I ended up just doing 2x6 walls and air sealing everything myself. When I mentioned exterior insulation to any builder around here, they looked at me like I had 2 heads. The one that entertained the idea wouldn't even estimate a price for labor.

[@thezfunk]

My buddy found that out interviewing builders for his house. I think he went through a dozen. Nobody knew what ICF was, nobody knew how to do exterior insulation. Most builders are just lick and stick up a shitty house and walk away. They don't care about efficiency or best practice at all.

[@bobe5710]

I've had a similar experience, except the few builders who know about and do this kind of thing are extremely expensive. Look up "Mooney" walls to break the thermal bridging.

[@justinjimenez6960]

Where abouts do you live? I live in the San Antonio area, and yes, the struggle is real here on this front. BTW, for those considering ICF, look into Helix micro rebar as a way to reduce the labor/time for working a rebar lattice into your build. I would have gone this route before the economy tanked and finances got screwey

[@canucktheory3271]

It's not just drainage, it's a micro moisture barrier requirement. When installing exterior insulation you can encapsulate moisture from the dew point in the wall. With EIFS, for example, you need a 3/8s air gap to accommodate any moisture. If you heat or cool the space inside you're going to have a condensation point in most cases. Ideally, there would be no fastener penetrations channeling hot or cold inside the wall unless there's a thermal break as well. In warmer, drier climates it isn't as crucial, but here in Canada, it is imperative. I love the details in the build, especially the bug screens. Keep up the good work!

[@WilliamLaakkonen]

[@FranciscoTChavez]

13:53, a trick I read about for mounting a TV to an apartment's wall comes to mind. You buy some 2x4s and some drywall to create a bit of a false wall to place on top of the real wall. Just make sure that the studs in the false wall line up with the studs in the real wall for attachment purposes. Now, in the false wall, you can cut holes (behind the TV) to run wires and stuff like. Then, when it's time to move out, you can remove the false wall without any major damage to the real wall. This comes to mind, because this might be a hand way to inset speakers.

[@1967250s]

At this point in building science, it makes more sense to insulate the outside of the house. It is much faster, and easier install than interior walls, and not a luxury like Scott says. My Dad was an architect, designed and built one of our houses in D.C., with extra wall insulation, but even then we had pipes freeze in the wall. And we also know that in Texas, it can and does get cold. Exterior insulation makes much more sense the more you think about it, as long as it can still withstand water and wind events..

[@JoeFidler]

I love the videos with Scott True!

[@MegsCarpentry-lovedogs]

Scott True Builds 52 minutes ago Good points. This is a real dilemma. A while back, I use to try to sell high performance and it was difficult for me. I'm not going to change what people are interested in. So here's what I do: For my spec homes, I have a specific formula, which does not include exterior insulation, but does include many high performance details. I can build those homes at a low enough cost to sell them at competitive prices to people that pretty much don't care about high performance. In fact, I don't even tell them until after closing. I do this because I just can't build any other way. Plus, it allows me to constantly learn, get better, and show what I'm doing to people that do care. Most of this showing is happening off line when people call our company. Ideally, I would be on KZbin more often to show this to a larger audience. I'm getting there. Then when people reach out looking specifically for high performance, we can dial in those details as far as they want to go with it.

[@iowawrench]

The single cable per hole electrical sealing thing made me think of how it's done in industrial applications. Might be able to do on homes also with far less labor and a neater / tighter final product. Search Eaton Crouse-Hinds EYS or conduit sealing fitting. They are used to seal off hazardous environments so by nature have to be air tight for say Class I hazardous gas locations. Could have the fitting inside the house to keep it out of the elements and use sealed conduit to then penetrate out.

[@iowawrench]

Video of fittings I'm talking about. kzbin.info/www/bejne/rKDRdGynZcl6hrM

[@tmurray12]

Solid episode. Good insight and a solid builder. Thanks Matt!

[@kschleic9053]

I feel like the absolute lowest cost / best result airgap solution would be for ZIP to texture the surface of their OSB 1/16" when they compress it at the factory, before they apply the air barrier material.

[@MegsCarpentry-lovedogs]

I agree. I live in zone 7 here in Canada and will be applying 6 inches of rigid foam on the exterior, furring strips with counter sink holes for the structural screws. I was going to do what Joe Lstiburek said to Scott, the textured tyvek drain between the sheathing and the first of 3 layers of rigid foam. If zip would texture their sheathing....Boom! Mission accomplished! 👍☺💝

[@corysanna2330]

Caulk dabs could be placed and used to seal the nail holes in the Zip sheathing. 2 functions in one step.

[@tanner6538]

I feel like there are so many builders who just check boxes and/or spec materials because they are the newest tech. Scott is a builder who actually considers the function of each item and whether or not the commonly-used components are overly redundant and the system as a whole can be better-engineered. He's a proper builder, rather than someone who installs homes.

[@wcbscout]

Love the efforts to practice building science within budget constraints. Having said that, the envelope would be more practical to be Insulated concrete forms, would be multiple steps of the build in one step and similar in cost if not cheaper.

[@Fedgery007]

I would hire Scott in a heartbeat.

[@asanisimasablasta]

I like the Spacers-- bit over the nailed holes in the Zip to make it more air tight-- vapor is less danger than air

[@ryansoo4000]

I enjoyed the video! With all the talk about sustainability and reducing waste in the world of construction the one thing that I hope Scott is doing with those Arlington boxes is that if he is not using the adjustable flange in some situations that he sends it back to the manufacturer. To create a part like that for a product takes a lot of energy, time and resources and to just throw it into a landfill where it will sit for the next 500 years because you’re not using it on one particular install is a total waste. If Scott returns it to the manufacturer they can just send it out to the next customer and prevent a perfectly good piece of construction material from becoming garbage. Matt, do you ever ask your suppliers if they would be willing to take back parts that you don't need at that time so they can be reused by the manufacturer?

[@stormagorist6129]

I love the out of the box sort of thinking he demonstrates. It is easy to just buy the latest and greatest, but overwhelmingly people cannot afford a home that is 2x-10x more than comparable homes in the area, even if the numbers work out over 20+ years. Last I read average time of owning a home is about 4 years... I really appreciate seeing the 1 inch foam detail on the exterior since that is what I am planning on doing. I first wanted two inches but it is (here) cheaper to buy two 1 inch pieces than 1 two inch piece, and you have the added advantage of two foil barriers. My current issue is trying to figure out how I am going to finish out windows with the unusual wall thicknesses. I've thought about recessing them so that they are flush with the interior wall, creating a shadow box effect, but I am not sold on that yet..

[@MrEdgardotcom]

I want to see you guys build with Hebel (AUTOCLAVED AERATED CONCRETE)

[@sergeykazantsev1]

Always been thinking about insulation from outside as well as from inside. But two 1 inch layers with end joints staggered - even better. Love the vent pipes go trough the wall on top. Because those galvanized pipes roof boots get rusty in few years, and plastic ones also can UV deteriorate.

[@caesarsoto3302]

Really detailed install, although I would use treated strips on top of foam. Maybe just bottom 2 ft.

[@terrydenoyer3772]

I get why you add the air gap behind insulation for a drainage plane, in your climate. Being in a northern climate, would worry that the loss in R value of the wall assembly would defeat the purpose not to mention the potential to increase condensation potential there.

[@tommartin1347]

I love the details for your house, you are an awesome builder. At 23:15 you show the plumbing vents exiting the side wall which makes the roof lines amazingly clean. I would be concerned about cavity nesting birds like sparrows and starlings entering the uncovered side vents. Since the lower roof is so close to the opening it might be less attractive to the birds but in Wisconsin we have trouble with any openings over 1” in a side wall.

[@grand04gt]

Amazing details and love that he mixes lower cost with the high performance. That venting area is a phenomenal idea (would likely not work with the snow in my area) but if you did monopoly framing and frame on top for the overhang as well as to vent the roofing would you in theory be able to run your vents into that area so they would all disappear completely?

[@elierhernandez1]

Try polyiso in the Midwest. Carpenter ants LOVE this stuff. They will channel it to an insulation value of R0! I have taken down polyiso panels on houses where only the aluminum foil was left. There was only dust in-between. All the way to the roof on 2-story houses. You have an obsession with foam boards, including ZIP, and it is time you pay attention to the insects that live on this planet and that obliterate this material!!! Customers be warned, you also need to pay attention to builders that don't know what they are doing.

[@e3a3c3]

This is absolutely true, and fire ants do it as well. Personal experience in Texas.

[@shubinternet]

That's part of why I like rockwool insulation for both interior and exterior.

[@JonDecker]

Rockwool is the way. Foil faced exists there too.

[@gijoyjoy]

Does that exterior outsulation protect from fires?

[@crabkilla]

What is the cost difference between poly-iso (aftermarket) versus buying Zip sheathing with it built-in insulation? It seems like you could avoid a bunch of these details, risk, and labor. More labor “passes” for all these materials means more opportunities for things to not be right

[@CrankyHermit]

I wondered about this too. Zip-R would save quite a lot of labor, while sacrificing the benefit of the foil layers. Not sure about the cost difference.

[@blacken700]

Would you use a foil face insulation in Maine

[@MegsCarpentry-lovedogs]

Here is a question for Matt or Scott or this community. Scott talked in the vid about Lstiburek suggesting placing the drainage wrap over the sheathing but inside of the rigid foam. I listened to Lstiburek in another vid suggest that in case water got between the sheathing and the most inside rigid foam it would have a space to drain. In doing more research there are building science people who do not include that drainage wrap over the sheathing and only over the most exposed rigid foam. We saw that Scott found even the dashes of liquid flash may not be effective to create enough of a gap. Remember, there is hydro tension to consider if the air gap is not wide enough. STeve Baczek talked about this on one of his vids. Can someone clarify, with being in zone 7 Canada, if that drainage plan is really needed? I talked with a builder here on Prince Edward Island, CAnada, where I live, and to eliminate any rain getting in between the rigid foam we were thinking of using the "brake" to bend aluminum to cap off the top. That would be the only place water could get in...maybe rain hitting it even under the eaves due to rain...and we are getting a lot of hurricanes now so wind direction is changing and more forceful. I continue to research and hope a few of you will answer. I might copy and paste this comment and add it to Matt's channel comments and Steve Baczeks as well. Cheers ☺🇨🇦 Long live our buildings👍

[@ponga782]

I love seeing you guys doing videos like this. They give so many great information

[@LuminairPrime]

Shout out to Scott for spray foaming his personal attic. We're afraid of locking important structures into spray foam, because what if there's a leak or maintenance that needs to be done? But it's an irrational fear not backed by evidence. Build things right and you will never need to touch the bottom of the roof in your lifetime.

[@misterlyle.]

Is a four inch deck screw sufficient in this application? Two inches of foam, 3/4 stock and almost 1/2 inch sheathing; that leaves about 3/4 inch penetration into the wall stud. True, four inch deck screws are a lot less expensive than 5 inch GRK screws, but I would have thought code required a minimum of one inch penetration into the stud.

[@phamlam3720]

Exactly. It is the reason I went with 1.5" foam. I assume they overdrive the screw a bit and got 1" of penetration into the stud. If you include the 1/2" sheathing, that is 1.5" of grip.

[@petrirantavalli859]

That's why at least here in Finland all exterior XPS wall products are a) grooved b) fomed from the seams with urethane (manufacturer's guideline) also XPS is non water or vapor permeable when properly sealed but it does degrade quicky from UV in direct sunlight (hence the aluminum foil). As for insulation XPS is roughly 1/2 as thick to rockwool pads for comparable insulation levels but pricing for XPS is also often doubled so it kind of evens out for costs but XPS is not fire proof which should be kept in mind on fire risk areas both inside and outside. Also should add that here we would build the wall the otherway around with XPS on the inside and zip or wind barrier mats would then be the exterior cladding or do a combination wall with rockwool between joists and thin XPS sheets for inside wall (acts as vapor barrier) and zip or wind barrier on the outside as we have never used those house wraps in Finland (and not really anywhere in Europe I think) except under roofing to divert water.

[@MegsCarpentry-lovedogs]

[@sparksmcgee6641]

Scott, I just clicked you site from here. Please paint your HVAC vents the color of the wall. One of those things that you can't not see once you've been in a custom market. Easy to just lay them out in the garage when the walls are getting done. Back of the tip and settings. You'll get another type of paint after a while.

[@cornpop7805]

I'll add one thing about out-sulation penetrations and even rainscreen penetrations. When possible (for wires, etc), angle the objects down slightly so water can travel away from the interior.

[@mindseyeproductions8798]

[@paulmessier8703]

Learned my trades in Canada, use polyiso for decades

[@branchandfoundry560]

Curious Question: Scott uses 4" deck screws to secure furring strips. We have 1/2" Zip sheathing, 2" PolyIso and 3/4" furring strips. So, at best we have the weight of siding beyond the 3-1/4" lever with only 3/4" bite. Is that sufficient to hold over time? I'm not bashing, I want to learn. Thoughts? Thank you!

[@billwernsing9360]

You have an additional 1/2” bite on the sheathing, along with a 3/4” bite on a framing stud. The sheathing has support strength in my opinion.

[@danbob1650]

[@seangordy2296]

Live FloFx, love Hydroban! Would love to talk tile tech anytime!

[@maximehubert2630]

I was thinking about the space behind the polyiso and a question came through my mind. On northen climate with exterior EPS insulation (not XPS or polyiso) on top of zip panel, is the concern with the humidity trap behind is less of a concern because if the perm rating difference between the EPS vs polyiso?

[@stevecrawford6958]

eps dries much better than xps and polyiso doesn't do so hot in the cold.

[@justinrutledge6090]

Using a 4in deck screw, well it's a 3/4 inch fur strip, 2 inches of foam insulation, 1/2 zip sheeting, so your going into the stud 3/4 of a inch, an then you fastner you windows an siding to the fur strips? Pretty Hardie recommends 2 inch solid penetration into structure for the installation of their product.

[@Prorex1911]

I’m curious if he doesn’t have the felt bug screen on top and only the venting in the soffit, won’t bugs be able to enter from the top through the soffit holes? I love listening to these guys. Great content as always!!

[@davidbeals6807]

Would it be a good idea to have installed the bottom layer of poly-iso with the foil facing in, as there is an air gap due to the black blobs of silicone, so there would be a radiant barrier for heat flow in both directions?

[@CrankyHermit]

Good question.

[@brettbowers]

Have a similar question regarding the creation of multiple vapor impermeable layers. Does he run the risk of creating condensation problems between the two layers? Especially with it being located outside the building envelope. Very curious to know.

[@jpvill4th]

I talked to Joe when I took his course on Renovation and the dimpled material he suggests has to do with air and moisture moving through the sheathing and providing a means for any condensation to get out of the apace between the sheathing and exterior plastic foam. The exterior insulation will not let any moisture through it so it a conservative way to take care of the unknown. Without it there is no way for any moisture to get out and the sheathing will rot.

I’m really curious of any ideas or advice on how to strap or a different technique when installing Hardie shingles to exterior insulation. Any ideas? Thank you!

can stucco be applied over exterior insulation?

What is that ratio of window to wall, when you start to suggest to upgrade to the next level of windows. Also it would be nice to have a graph showing those ratios and how they act at different times of the year.

There are "ball head" push pins that have 1/4" or 1/8" plastic spheres as the head. Maybe sticking the business end of a few of those into the backside of each foam panel during installation would work as a cheap, uniform, and time-effective way to space them off the zip for a drainage plane? Too bad "Spaceballs" is already taken.
