CDX and OSB as Vapor / Air Barrier
I have read most of the articles about CDX and OSB as an air and vapor barrier. It seems that CDX is the best option for air tightness due to a lower leakage rate but a coat of vapor preamble paint(most basic primers) should do the trick?
Intello seems like great stuff, but it seems like for some scenarios a rigid durable surface behind the drywall such as CDX or OSB could make sense for alot of spaces?
