Thermacore® Insulated Garage Door FAQs
Is an insulated garage door worth it?
For most Michigan homes with an attached garage, yes. An insulated door helps keep the garage warmer in winter and cooler in summer, which eases the strain on rooms next to or above it. It also tends to be quieter and sturdier than a single-layer steel door. For a detached, unheated garage, the benefit is smaller.
What is a thermal break, and why does it matter?
A thermal break is a barrier that separates the inside and outside steel skins so cold can't travel straight through the metal. Thermacore® doors pair thermal breaks with seals between sections to cut air leaks at the joints, which are a common source of drafts on garage doors.
How is Thermacore® different from a basic steel garage door?
The difference is insulation and sealing. A basic steel door may be a single steel layer, while Thermacore® doors sandwich polyurethane between two steel skins and add section seals and thermal breaks. If you want a simpler steel door, compare it with our Traditional Steel collection.
How do I keep an insulated garage door sealing well?
Check the bottom seal and weatherstripping every year and replace them when they crack or flatten. Keep the tracks clear, and have the springs, rollers and opener lubricated and inspected. Our Red Ribbon Service Plans include a safety inspection, lubrication and a 25-point inspection of the door and opener.
