How do I seal the air barrier at the top of the exterior wall?
Hello, The air barrier was installed up to the top of the exterior wall. I wonder how to prevent the air from entering between the top plate of the wall and the OSB r4? The roof trusses are already laid on the top of the wall, so it is difficult to put red tape on the length of the wall.
I have the impression that the air barrier should have been installed over the top plate and the roof trusses installed on top afterward. How to air-seal it at the top of the wall opposite the plate? If I just put red tape on the wall at the top, the outside air could come in through the soffits, then enter between the OSB r4 and the top plate and end up inside the wall. Thank you
