| installing foil faced polyisocyanurate foam
I'll be doing drywall in my walk in closet, and to increase 'R', I'll be adding 3/4" foil faced polyisocyanurate foam underneath the drywall.
One side of the foam is covered with black plastic, the other is with aluminium. Which side should be facing inside? Or does it really matter?
TIA

Fort Wayne, IN | There was a discussion on this a while back. Since you are putting this on the inside, you would want the foil on the inside. |
