Therma Classic

CONSTRUCTION: The Therma Classic is made from hot dipped galvanized wood grain textured steel skins that are embossed with raised panel designs then sandwiched with a polystyrene core. This type of construction forms a thermal barrier between front and back of door. 20 Ga. 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. Therma Classic doors are available in 2 design series. The S Series doors have multiple vertical panels embossed to form the various designs. The R Series doors start with 40″ x 24″ embossed recessed panels. Then roll formed pre painted wood grain textured aluminum design elements are mechanically attached as well as bonded to the face of the recessed panels to form a multitude of designs.
