Hello, I am a complete amateur and have some Q.
For one, How can it matter if cels or glass or whatyever are air barriers or not when one places a rigid layer over them? I applied an air hose to a piece of drywall at 120 psi and guess what? It didnt go through to the other side. So why put plastique between the drywall and the insulation?
