The Classic Steel Model 8500 compliments a range of different home styles with its fresh lines and eye-catching paneling. It has an impressive R-value of 16.22, which is achieved by its composition of two layers of steel surrounding a thick layer of foamed-in-place polyurethane insulation. This will improve your home’s thermal efficiency, reduce outside noise, and help the door operate more quietly. It also comes with integrated struts for rigidity and strength, pinch-resistant panels.
