Insulation Type: Polyurethane
Recessed Combo Panel Sandwich Door
They may look like wood, but these models are actually all-metal, maintenance-free insulated doors. The front and back skins are made with a pre-finished, wood grain embossed steel and the cores are filled with high density polyurethane for optimum weather protection. An all-metal exterior is used on both the panels as well as the overlays to ensure years of worry free maintenance.
