Self adhered house wrap adhero vs hydro gap sa do the dimples help walls dry with heavy exterior foam?
I came across hydro gap sa and was wondering if this product may not help with drying potentials in a wall with thicker exterior foam like my own house will be.
The 1 mm gap is enough to allow moisture out while not allowing much of any cold air behind the foam. I’ve seen other products at 1/8 thick say it effects the r value by about 5-10% so I’m guessing this would be even less.
The hydro gap doesn’t seem to have as good of air permeable ratings or water as adhero sa but it still far exceeds any “normal” house wrap system. I believe it’s at .011
Main question being will the hydro gap help aid in allowing a thick exterior insulation to dry to the exterior at all given the gap it creates and it’s perm rating?
Appreciate all the help I’ve been given so far I have very few items left. Foundation is being poured this coming week and basement. Trying to order the remaining things I need.
