Getting barriers straight
So let me clarify.
I can sheet a house in plywood, tape or goop the seems and nail holes, and this can be considered my air barrier. Correct?
What are the biggest problem spots for air leakage to look out for? What kind of tape is trusted (I know there are article on this, I will search). Is liquid applied goop a better solution? More expensive? Labor saving?
After the air barrier I need a WRB, correct? This can be Tyvek, liquid applied membrane, tar paper.
Or…..I can get them both with Zip Systems, if I can accept OSB as a building material. If Zip made a plywood version it would be a perfect product. Probably expensive though. The WRB has to be vapor permeable, Correct?
thanks for clarifying.
