Attaching rigid foam to concrete
Got a question…
What’s the best way to attach rigid foam sheet insulation to concrete? I’d like to insulate and sheetrock my basement walls. I read where Fernando Ruiz from Omaha uses Z furring and 2’x8′ sheets of rigid foam, but I was afraid the cold would migrate through that galvanized metal and cause condensation on the backside of the warm drywall. The sheetrockers I talked to today said they hate attaching to anything but wood.
