Smart MemBrain in Zone 5
As some of you may have followed my other Q&A posts, you may know I have installed the Certainteed brand Smart MemBrain on the interior side of my walls.
I live in Zone 5. My walls are 2×6. Exterior to interior is vinyl siding – Green guard Raindrop 3D wrap – 7/16″ OSB – 2×6 studs w/ R-23 mineral wool insulation – smart MemBrain – future 1/2″ rock – latex paints.
I was under the impression that the membrane is a good idea. However I talked to some older builders who say poly on the inside destroyed homes. They also said either cellulose or fiberglass was used in the walls. So I have two unconventional products that are not time tested here. Mineral wool and the smart membrane. Should I be concerned? Am I doing things proper so far? I am assuming the poly for them was bad because of their insulation type?
