You are one of my favorite channels to follow for home improvement projects. I'm actually running into the similar situation, i have 1" rigid foam and building up 1" buck around the opening where we can install window (nailing fin) on the top it looks like perfect solution, this way the foam will be flush with the fin. The only question is when reviewing the code and installation instructions it says: "Embedment must be a minimum of 1 1/4" into the structural framing" So is the 1" buck counts as the "framing" since technically it is 'outside' of the wall framing? My window depth is 3.25" that leaves 2.25 before the fin minus the sheeting 0.75" which leaves 1.5" embedded into the frame (2x4) If we build the buck 1" out, that will technically leave the window only 0.5" inside the frame (2x4)

@burningdust 3 жыл бұрын

That’s a really good question. Often I see this type of exterior foam insulation project come together nicely but when it’s time to install stucco or vinyl siding over it, seems to become a “ok now what?” Type of scenario. Also there’s usually other fixtures such as mailboxes and lighting etc that need to be adjusted to accommodate the foam. I’ve heard it recommended in another video to install the foam over the studs then osb / plywood on top of that so you have a substrate to fasten siding to. Just doesn’t seem to be a good way to do this overall. Wish there was a system out there that made sense.

Hello. Do you have any video about how to insulate an exterior brick wall?

Do you have a video on how to put vinyl sliding over styrofoam board

@HouseImprovements 4 жыл бұрын

Not specifically. It is really the same but use long enough nails to penetrate into wood buy 1”.

Thank you for this video. My heating bill is going up, so I want to install a similar insulation styrofoam on the top of my brick wall. Question - do you allow the gaps in between the foam sheets to allow the thermal expansion? Why don't use the pressure-treated wood for the outside styrofoam support? Also, if I use the blue tapcon screws to attach the styrofoam to the wall - they may rust, but will they rust under the siding? Again, if I will use a siding above the styrofoam then how can I nail/screw it to the brick wall behind it? Again the tapcon screws will rust.

Is any chance mold can appear between foam board and home wrap? As I see there is no gap for venting. What do you think?

@bcoldwell1 3 жыл бұрын

I had the same question. You now have a vapor barrier inside behind you gyp, on the warm side, and with the xps, you have added another vapor barrier. Kind of possible to "trap" any vapor moving from warm to cold. There is - I have heard - a rule of thumb about what % of you R value can be outside the housewrap, vs on the warm side. I'm doing the same as done here, so need to figure it out. Roxul is vapor permeable, so isn't an issue I don't think.

This is why it is not a good idea to use XPS foam (like the one used in this video) on the exterior side of the house. Instead you should be using EPS styrofoam. Because eps foam will not trap vapor.

@Faruk651 3 жыл бұрын

There are EPS styrofoam sheets that has channels on the back side which helps air movement and ventilation. Durock has Puccs Styroams as an example.

I'm a contractor and don't trust nailing the vinyl siding though the 2" styro. I decided to strap on top of the rigid. Have you ever installed vinyl siding that way?

@HouseImprovements 4 жыл бұрын

I have not but you can. IMO it is really not needed but it won't hurt anything.

@NateTheGreat848 5 жыл бұрын

how do you install the siding then? Use 3 inch nails then? Does it not defeat the purpose of thermal bridging then to put a million nails in through the foam? No rain screen or furring strips?

@ducebigalow8834 5 жыл бұрын

Typically yes, longer nails or I would use screws for vinyl siding. I would not strap the rigid prior to vinyl siding, as you could get air behind it thus rattling the siding.

@vap0rtranz 5 жыл бұрын

@@ducebigalow8834 odd. Never heard of rattling siding. Where has this happened? Several builders do recommend @NateM's idea of furring strips. The air gap also acts as a water runoff if there's a water barrier there for anything the siding doesn't stop (like backed up gutters, melting ice dams, etc.)
