Air sealing specifics: OSB and WRB
Hey There Folks –
Excuse me if this is a bit repetitive, but I’m working through a few details air sealing our house and had some questions come up.
1 – Any issues with sealing from the bottom of the osb to the eps foundation foam? I’m not sure the 3M All Weather 8067 will seal to the EPS, so was considering spray foam or caulk. We left an 1/8 inch gap as a capillary break below the osb, and bottom plates have sill seal and two beads of caulk, but the osb is not sealed to the bottom plates.
2 – Should we seal the edges of the window and door rough openings? They will get flashed later but integrated with the WRB, which seems like a different layer, and I take it WRB’s are not generally air barriers. We plan to use Tyvek Stuccowrap or Commercial Wrap D.
3 – Any improvement in 3M Red Tape (8087) over Tyvek Tape for the WRB?
By the way, got my hands on a really nice fluke thermal imaging camera. What an awesome tool! I’m really excited to put it to the test once the exterior foam is on, and going forward. I’ll try to post up some photos throughout the process.
