SwiftWall Pro Panels are made of ABS with aluminum joiners and polyisocyanurate core (Class A fire-rated material optional) featuring an R7 insulative value. Our non-hydroscopic SwiftWall Pro Panels also help keep the noise down with a STC21 sound rating. Standard Panels are manufactured to a sturdy 4’ wide and 1” thick, and come in heights of 4’, 8’, 10’, 12’ and 16’. Panels can be stacked as high as required by using C-Channels and a support skeleton such as metal stud framing. This model comes with an electrical socket fitting.
