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.

Rusty provided excellent service. Repaired the garage door opener efficiently and in very little time, with the most economical solution. I am a long time customer, and would certainly do business with Overhead Door again in the future.

I just had my Overhead Garage Door springs replaced this morning. One of the strings broke three days ago and “Rusty” (technician) came out the sane day and temporarily clamped the spring so I could use the garage door until he could order both replacement springs. Today Rusty replaced the spring and he was professional, polite and efficient. I give him and Overhead Garage Door Company “Five Stars” on their service. I will recommend Rusty and Overhead Garage Dood Company whenever I am asked to recommend a garage door company. Good job, Rusty. BFH [ Read Less – ]
