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.
