The Therma Series Commercial/Industrial insulated steel garage doors are rugged and beautiful. They are designed to have a sleek and appealing appearance with great weather resistance. Therma Series doors are made with a sandwich type construction, steel outer skins are formed and then pressure bonded to a polystyrene core giving the door maximum strength, a natural Therma Break and superior insulating efficiencies. Three insulating values are available - R10.4, R12, and R16.
CONSTRUCTION: The Therma Series doors offers 3 different models all are made from hot dipped galvanized (G 40) wood grain textured steel skins that are sandwiched with a polystyrene core. This type of construction forms a natural thermal barrier between front and back of door. 20 gauge steel backer plates are toggle locked to the inside of the back skin prior to assembly. Exterior skins are secured to a polystyrene core with urethane adhesive, a method of construction that is unparalleled in strength. R16*, R12* and R10.4* to fit your needs.
* R Values are calculated specifically for the colder climates and offer the best long term insulating value.
