Very good video, thanks. Could I just mention, when you state you are adding additional insulation in the stud cavity on the interior, saving money is possible as a vapour barrier is not required on the inside if the insulation ratio is 2/3 exterior to 1/3 interior. If less than that, a smart or permeable vapour barrier such an Intello or other would be needed. It sounded like you were going to add a lot of insulation on the inside but I didn't hear anything about an interior vapour barrier. Might be helpful so someone can determine whether to use 2 vapour barriers or one.

What is the r value of the windows? I was blown away when I recently saw some information on the negative impact to the thermal resistance of the complete wall assembly windows cause. A surprising detail was the fact that increasing the wall insulation, even doubling it, had very little effect on the r value of the entire wall assembly if low performance windows were part of the assembly. Basically a typical house built with regular r 1.5 windows could be built with r 13, r21 or even r30 walls but the total wall assembly r value improved only a point or two with the thicker insulation and no real insulation benefit could be measured until the windows r value is over r4.

I understood it be a system, whereby it has to be vented top and bottom to really be able to dry out well.

I would like to see the rainscreen details at the top and bottom under different circumstances. For one area I ran my rainscreen directly into a vented sofit. In another area the sofit wasn't vented so I left a 7/16 inch gap at the top. In one spot the wall was above a shinglesd roof so left a 7/16 gap above the shingles and foam base. I used bug screen at top and bottom in all locations and rested the foam on wood or PVC so it is never directly exposed. Not sure if leaving the gaps the way I did is correct though.

I would still ideally want that air-water barrier to be outboard of the external insulation. The sweater outside the gore-tex jacket doesn't help much if it gets soaked itself and the wind can blow through it (though this might be more true for comfort board than those polyiso sheets.) For a stick-built home, my ideal would be a 2x12 treated base plate with another 2x8 base plate on top of that toward the inside. Frame with 2x8s or 2x8 T-studs 16" on center. Sheath with 1" plywood and use some of those Simpson strong ties through this sheathing, through the 2x8, and into the double base plate (use 2x the anchor bolts into the concrete.) That's a strong wall. Inside the 2x8s, spray 3.5" of closed cell foam, and top that with an R15 Rockwool batt. Outside, where you still have 3" of 2x12 to work with, put your 2 layers of 1.5" polyiso sheets just like Matt does here. You don't really need to screw them down though.. just primer that inner layer of sheathing and use 3M spray adhesive to stick them to the wall and to each other. THEN comes your final layer of sheathing. Either ZIP board or plywood plus AlumaFlash (UV40) for your barrier. I like the UV40 because you can run screws through your external sheathing, 3" of polyiso, then into the 1" internal sheathing and the studs, and THEN cover it all up with that peel & stick house wrap. Your framers may grumble, but you can reward them, and you would have an R60 wall that would probably stand up to an EF3 tornado, especially if you face it with rock, as you should.

Racking is structural even if code doesn't recognize closed cell foam as adding greatly to that. We have 9' ceilings on upper and lower levels and a structural engineer recommended closed cell over batts for that reason using 2x4 construction. Code says 2x4 construction was OK but adding additional racking strength via foam makes sense, especially when using thick Zip-R. You have less R-value with 4" of polyiso than we have with 5.5" of polyiso and very deep windows/doors that we don't like the look. We looked at ICF and rejected due to high pricing and thick walls.

I have a dream. That is to take my crappy 90s Bill Milburn house in Austin and energy retrofit it with outsulation like this. The house is clad with brick on the front and halfway up both sides. The back and upper sides are hardboard siding that is falling apart. I also want to reframe the window openings in front - they are too big and have these trite arches that need to get gone. My plan would be to apply liquid flash over all the brick and reframed window openings. The siding would be removed, pink insulation replaced with Rockwool and then covered with Zip panels. Seams between brick and Zip would be sealed, natch. Then cover the whole thing with thick rigid Rockwool - maybe 8 inches. All of that is covered with corrugated galvalume panels and maybe some other unconventional cladding materials for esthetics. The roof overhangs would be cut to be even with the cladding, so no overhangs (similar to Matt's Perfect Wall House). Additionally the interior walls with brick on the outside would have the drywall pulled down so new inulation could be inserted.

@billvojtech5686Ай бұрын
I know you have a rainscreen under the cladding, but I'm also worried about water, either rain infiltration or condensed vapor escaping from the building, getting trapped between the Zip sheathing and the foil face of the first layer of insulation. Would it be smart to put a layer of something like Benjamin Obdyke Slicker rain screen on the Zip before putting the insulation on? Would this defeat some of the insulating properties of the insulation?

How do you attach the 5" jam extension to the buck you made? Why did you do the windows differently? For the newbies, maybe you could do a video with details of how the bucks are made, attached, flashed, angled (5 degree pan) and then how the bucks are made, attached, flashed. You jumped over a huge detail that if down poorly will just rot. You used cedar for the jam extension, how about PVC or what other possible materials would last 50-100 years because if you ever have to fix a problem, it seems like it would be a compete PITA to tear out the jam and rebuild.

Excellent feedback. Also, some good questions. To learn more about those cedar trims on the outside of the house go check out my “the Risinger Build“ video series. If you go to the siding episode, I took some time explaining how we built them. Also know that they are face screwed so they could be removed easily in the future. I wanted to be able to change out these Pella Windows And access the flange. I think I might actually do a more end of answer on this for my Instagram feed. @RisingerBuild thanks again for watching.

R-60 is the recommended insulation value for any surface without restrictions. Passivhaus demonstrates how that can be done for prices comparable to more uncomfortable insulation practices of the past.
@Supercharged1112 күн бұрын
It's worth mentioning that, up north at least, the requirement for exterior insulation can drive one to go no less than 3" in thickness to negate the need for an interior vapor retarder. Also worth noting is that the performance of a polyiso sheet degrades significantly in colder temperatures whereas EPS or XPS will start performing better since these sheets get their R value at around 70 degrees or so. I wonder if those windows are custom ordered for those thick bucks? If it's Matt's own house, then rhe answer is yes. 😂

Are rain screen and air and water barrier separate things?
@beerbellybob29893 күн бұрын
Yes. Building science has evolved in the last 20+ years. These are now considered three distinct "control layers." Air and water barriers can still be accomplished in one layer (ex. ice & water shield over the entire roof/wall) but what Matt did in the video is use zip sheathing with taped seams and liquid flashed penetrations. The rain screen is accomplished by separating the siding from the wall (creating an air gap) with furring strips- wind driven rain that gets through the siding will trickle down the backside of the siding and not wet the wall. It the wall did get wet somehow, the air gap will allow for easy drying.

You can do 10 to 20 cm EPS insulation on the outside with stucko finish and you are done. This is what we usually do in some parts of Europe.
@joeywharton5662Ай бұрын
I've posed the question before - but why not just attach polyiso to the stud, sheathe over the poly, then spray foam the interior cavity, so the poly iso sheet is in direct contact with the foam? Poly increases in R value the thicker it gets, and you reduce thermal break to a minimum. Im building a house and did it. 2.6" of poly between stud and sheathing/roof deck, open cell spray foam cavity. Walls R45, ceiling R65. Sided with 4 x 10 cement fiber, attached with 4.5" hex head screws going into studs. Monopoly framing (no eaves), vaulted & closed ceiling. Single head mini split, 24k btu mini split heats 1200 sf, no ducting or roof penetrations. Its so tight i have to keep heat super low even when its snowing outside. I did invest into triple pane windows. It just seemed like the most logical thing to do, easier, a fraction of the cost and better performance, less points of failure 🤯
@niktak1114Ай бұрын
Sheathing directly to the studs and having the insulation on the outside is better for the longevity of the sheathing and provides better shear strength since the nails don't have an essentially unsupported span in the middle.

Dumb q - why don't we need to leave an air gap at the foam-zip interface to allow for air movment and drying?
@beerbellybob29893 күн бұрын
If you "allow" for air at the foam-zip interface, you'd defeat the insulation and the zip would be cold (or hot). The foil-faced foam will prevent drying to the outside, so the zip (and all components beneath the foam) will need to dry toward the inside. Therefore (not discussed in this video but surly in Matt's others), drying potential of modern airtight construction needs to be considered. For instance, one would not want to use vinyl wallpaper on the inside of this house as it would act as a vapor barrier (different from a vapor retarder) and prevent drying to the inside. It's all system now!

@@throngcleaver I'm from Austria, right next to the slovenian Border and we are doing like 2 layers of 6" isolation on new houses. And this is to the outside of 12" thick brick walls. I have a wooden framed house here but we used roughly 4" by 14" (8*28cm) studs that got filled with cellulose insulation. On the outside 6" woodfiber insulation blocks were nailed on and on the inside a high density wood fiber sheet with taped seams is used as a vapor barrier. Than we put additional 2"by4" studs on the inside of the walls as an installation cavity which then is double planked with another high dense wood fiber sheet and gypsum fiber interior sheet. Total wall thickness is around 24".
@throngcleaverАй бұрын
@Wiesi22 Wow! That is some serious insulation! Most homes in the U.S. have 2"x4" studs, with either plywood or OSB sheathing, and fiberglass insulation. Then 1/2" drywall inside, and cheap vinyl, steel, or aluminum siding on the exterior. Total wall thickness is 5 to 6". Many more modern homes have 2x6 studs with 6" of fiberglass, but it all depends on cost and climate, as I'm sure you are aware. It's nice to see that more homes are getting built with rigid foam, or spray foam to reduce heating and cooling costs. Thanks for sharing that information! 😁
@bradyusko6333Ай бұрын
I was doing my build like that till I shot it with a thermal camera last winter and saw heat escaping through the cracks and from behind the sheets of insulation. Also I thought about it and did some quick calcs, each screw roughly equals a 14 inch long 2x as metal is over 200x as thermally conductive as 2x wood. I honestly don't know how much it's going to make it better but I went to a stand off system where in this house I used t-stud screwed to the ICF walls then spray foamed to near the face of the t-stud, about r-32+-. It eliminates the air movement between and behind the sheet foam and the thermal bridge of the screws as they are in the flat 2x of the t-stud with about 3 inches of spray foam on top of the screws. Spray foam is also a good water proof layer and there is about a 1/2" air gap to the siding, rain screen. I'll be posting it on my KZbin Chanel in a couple months. I'll try to remember to add a comment with a link in the future. Would love to know how air movement in sheet foam and or rock wool outside insulation like this actually affects the true r-value or thermal efficiency? I could see it clear as a bell on a thermal camera on a icf house covered in 2 layers of 6" eps 4'x8' sheets offset seams.
