The ThermoMark™ 5200 doors combine strength, insulation and aesthetic appeal for applications that require all three features. Made of hot-dipped galvanized steel, they are designed with a wood grain finish in either a raised panel, Sonoma panel, or flush profile in a variety of colors. Foamed-in-place polyurethane insulation helps improve the thermal efficiency of a building, offering year-round comfort while also helping to provide quieter door operation.

Materials & Construction
The ThermoMark™ 5200 is manufactured using our patented, continuous foamed-in-place technology, in which the polyurethane core is securely bonded to hot-dipped galvanized inner and outer skins. This process gives the ThermoMark™ 5200 outstanding thermal, strength, and bonding characteristics while creating a door that is significantly more efficient than conventional insulated steel doors. A designed-in joint seal also helps save energy by preventing air filtration.
The ThermoMark™ 5200 is designed for easy installation, rugged durability and longer life. Features such as the 18-gauge steel end caps give the ThermoMark™ 5200 increased rigidity, while the factory finished interior and exterior hot-dipped, galvanized skins make installation easier, add life to the door and provide greater durability. The ThermoMark™ 5200 also features hardware plates at all fastener points to add durability and extend the life of the door.
