I have a window that I'm looking to remove from the middle of the kitchen and replace with cabinetry. I will replace the opening with new framing and OSB for sheathing outside. My question is regarding house wraps, I'm thinking of using Tyvek in the area and taping it with the preexisting using sheathing tape. Lastly, cover with brick. Is this the correct method to do it? And, I'm thinking of doing this in early January, knowing the weather, is there a way to safely progress the project with the cold weather?
You have a couple of issues: 1) moisture barrier, 2) vapor barrier, 3) wall insulation
Yes you need a moisture barrier and it needs to be installed correctly. Tyvek is fine, but I’d make sure it’s installed in “shingle fashion”. That is to say, make sure the top edge is tucked under the existing moisture barrier and the other 3 sides overlap the existing moisture barrier and all 4 sides well taped. (Be sure to check 6-8” back on the existing moisture barrier for cuts, splits, etc. because they could have covered them up when the window was installed.)
You need to match the existing vapor barrier or it will show a different “dryness” on the face of the brick wall. Vapor could escape out the wall and show a slight wetness on the face of the brick.
same with the insulation where the window was installed. I’ve seen where heat will travel through a wall at a different rate and show an area where the wall dries out quicker and it looks like a patch from the exterior.
Using the correct mortar and installing the bricks so they blend into the wall is more of an art than science. This may be the most difficult.
