1-1/2″ wide rigid foam strips on interior of wall studs?
I was recently speaking with a contractor who said a builder he knows of is installing 1-1/2″ wide strips of rigid foam on the interior side of each wall stud to stop thermal bridging. He is doing this as a more affordable method than applying rigid foam to the exterior. He is the installing furring strips for drywall. Is anyone doing this? I am also curious how thick these strips would have to be to effectively stop thermal bridging. It seems reasonable to me but I want to make sure this approach would be beneficial.
