Looking at using black sheathing for air sealing /baffles cathedral roof
I’m looking for a materiel to constuct some homemade baffles to provide an air gap for a dense packed cathedral roof. The trusses are 32″ inches tall with a 1/2 inch plywood deck on top. I understand the need for a gap to allow the deck to dry to the soffits. I’m looking for a material that is permeable enough to allow the cellulose to dry to the gap while providing an air barrier as well. I was looking at this
It claims to have a pereance of 30 but I’m a little concerned about its durability and I have no idea if it s suitable as an air barrier. Has anyone come across this situation and what solutions had you come up with.
