General’s Advantage Door is a three layer product, made with a 1-3/8” thick polystyrene core sandwiched between two 26-gauge pre-finished steel skins with a thermal break. The steel is protected by a G60 galvanizing layer topped by a heavy duty two-coat baked–on polyester paint system. The rated R-value is 6.7 and the door is available in four colors: White, Almond, Brown, and Sandtone. This door is used by custom home builders and is a very popular replacement door.
