Therma Series

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.
