Thermacore® Insulated Collection

Premium insulated garage doors for maximum thermal efficiency and design flexibility.

Thermacore® Collection steel residental garage doors feature premium insulation construction and design. By investing in our insulated residential garage doors, you can significantly reduce energy loss and minimize heat transfer, ultimately leading to lower energy costs. These doors feature cutting-edge insulation materials that effectively block out cold drafts in the winter and keep excessive heat at bay during the summer, creating a more pleasant environment inside your garage.



Product Features

Thermacore® Construction – Incorporates a continuous layer of CFC-free polyurethane insulation, which is foamed-in-place, between two layers of steel that resist corrosion. This construction design maximizes thermal efficiency and minimizes heat transfer.

In-between section thermal seals – Equipped with thermal seals positioned between the sections, these seals offer exceptional resistance to external elements. With an impressive air infiltration rating of up to 0.08 cfm, they effectively prevent the entry of drafts, ensuring a well-insulated garage.

Backing – Thermacore® products come with an interior-side steel backing as a standard feature. This backing not only adds strength to the doors but also gives them a clean and polished look from the inside.

Embossed wood-grain texture – Enhances the visual appeal of the garage doors, giving them an attractive and sophisticated appearance.
