Foil backed OSB in vented roof?
I didn’t realize that the building supply company / builder had gone with LP Techshield for my roof sheathing and I am concerned that it could cause moisture issues, I can’t find a moisture transfer spec on the material…only that LP promotes the holes that makes in the foil layer to help with drying.
I am in zone 4a and have vented attics via ridge and soffit venting. Should I be worried about having this material on my house?
