ai6yr, Before/after OCD insulating spree with FLIR and expanding foam. First image shows a massive thermal hole (between the fish) against a hot South facing wall. Second image is the same hole filled with expanding foam (cooler than the rest of the wall). Very expensive vs. Fiberglass batts, but this room typically overheats badly in summer. #insulation #weatherization #disasterremodeling #remodeling #flir
