I have my 1500 wrapped nicely in fiberglass. But the front face is a little different, since there is only 4" of space from the front Garn surface to the "ring" around the air collar. Using metal studs, which I believe are only 3" wide, but correct me if I'm wrong, leaves me with only about 1/2" between the stud and the Garn face.
What do people use here for insulation? I hate the idea of placing the metal studs directly against the Garn....heat transfer would be nuts. Obviously I can get R13 fiberglass or so between the studs....but I still want a good thermal break between the Garn face and the metal studs.
I'm not sure polyisocanurate would hold up to the heat, nor extruded polystyrene.
Is Roxul or similar available in 1" "sheets"? Or a rigid fiberglass product?
Thanks! Bruce
