Thermacore Collection

When only the best will do, the 490 Series exceeds expectations. This door features patented Thermacore® construction -- a CFC-free, foamed-in-place polyurethane insulation sandwiched between an interior and exterior skin of galvanized steel.

Industry-leading EPDM between section thermal seals minimize air infiltration and thermal transfer. A 17.5 R-value makes the 490 Series among the most thermally efficient doors you can buy.

Overhead Door Corporation's Thermacore® 190 Series doors feature the high quality of our patented Thermacore® metal-foam-metal sandwich construction.

Interior and exterior surfaces of the door are made from hot-dipped galvanized steel, coated with a baked-on primer, then finished with a baked-on coat of polyester top coat paint for maximum protection against rust. The core of foamed-in-place, CFC-free polyurethane insulation provides exceptional energy efficiency (R-Value 12.76). Full width weather seals between door sections, and an EPDM, bulb-type bottom weather seal enhance the door's superior thermal efficiency and provide a barrier against wind and rain infiltration.
