Thermacore | Energy-Efficient Insulated Garage Doors

Thermacore Collection – Models 5720, 5740, & 5760

Our most popular door, the Thermacore Collection showcases the epitome of thermal efficiency indoor design. The 490 Series stands out with its patented Thermacore construction, a blend of CFC-free polyurethane insulation encased between galvanized steel layers. Boasting a remarkable 17.5 R-value, this series sets industry standards with EPDM between-section thermal seals for minimized air and thermal transfer.

On the other hand, the 190 Series, another gem from Overhead Door Corporation, features the signature Thermacore metal-foam-metal sandwich construction. With hot-dipped galvanized steel surfaces and two layers of baked-on protection against rust, its core insulation ensures stellar energy efficiency, marked at R-value 12.76. Full-width seals between door sections and a robust bulb-type bottom seal amplify the door’s thermal prowess and resilience against the elements.
