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.

Curtis from the Parts department replied quickly, advising that their records showed the install and the type of seal needed. Great service-Thank you, Curtis! [ Read Less – ]

Kyle was the associate who found replacement parts for a garage door that had no identifying info anywhere on it. I needed window dividers on a condo door that were glued to the glass. A couple of the dividers that came off the door were lost and the unusual design was difficult to fine. Kyle was able to search through a pile of extra leftover parts and found exactly the correct style I needed. I wish I had gone to Overhead D C first. It would have saved me a lot of time. Plus, Kyle was very pleasant to work with. That’s a bonus !!! Steve [ Read Less – ]

I cannot say enough good things about my experience with Overhead Door. From beginning to end, the entire process was friendly, easy, professional, and refreshingly straightforward. Jason, my sales representative, was fantastic. He walked me through every step, answered my questions, explained my options, and made sure I understood exactly what I was purchasing without ever making me feel pressured. When I was researching garage door companies, I unfortunately encountered some pretty shady business practices elsewhere, which made me appreciate Overhead Door even more. They were transparent and professional from the start. I also really appreciated learning that they **do not contract their work out**—the people doing the work are their people, and that mattered to me. Everyone I dealt with was friendly, knowledgeable, and easy to work with. The installation went smoothly, and after dealing with my old garage door, I now have something wonderful: **a quiet garage door that actually works!** Great people, great service, and a company I felt I could trust. I would absolutely recommend Overhead Door to anyone looking for a garage door or opener. It was worth every penny. [ Read Less – ]

It wouldn’t be Monday without a hiccup entering the work week. I pressed the garage door button to raise the door, and the door lifted an inch or so and dropped back down. Pressed the button again, same result. Upon closer inspection I saw the tension spring had snapped sometime over night. I called Overhead Door right at 8:00, and they had AJ over to my house at 9:10. AJ had my spring in stock in his van and replaced the spring and put everything back together 40 minutes later. AJ gave friendly, efficient service with a smile. [ Read Less – ]

Went to get remote garage door opener repaired. Could not repair it so purchased a new one. When I got home I could not program the remote because I had to get on a ladder and remove a lens cover from my Phantom which I was not able to do. I called service and scheduled a service call. They were prompt and within 10 minutes remote was programmed and the young man checked to make sure the other remotes worked. The 3 young gentlemen I dealt with were so very gracious and helpful.
