Wayne Dalton’s ThermoMark™ Models 5150 and 5200 are the ideal choice if you’re looking for a commercial door that has a combination of strength and insulation. Foamed-in-place polyurethane insulation helps improve thermal efficiency of a building a minimum, offering year round comfort while also helping to provide quieter door operation.
ThermoMark™ Models 5150 and 5200 use Wayne Dalton’s patented, continuous foamed-in-place technology, in which the polyurethane core is securely bonded to hot-dipped galvanized inner and outer skins. These doors have an 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.
Features such as the 18-gauge steel end caps give these doors 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. ThermoMark™ 5150 and 5200 also feature hardware plates at all fastener points to add durability and extend the life of the door.
We offer these doors in an array of colors and panel designs that give these doors the beauty and appeal of a residential door but meet the size and strength requirements needed for a commercial or industrial application.
