How do insulated garage doors impact home energy efficiency?

The exterior walls in your home are insulated. If you take your garage door (virtually an entire wall) and don't insulate it, it loses a ton of energy through the door. When the garage stays too hot or too cold, the house then has to work harder to maintain temperatures inside, which increases your energy costs.

This matters most if your garage is attached to your house or sits below a bedroom or living space, since heat moves directly through that shared wall or floor. It also matters if you use the garage as a workshop, gym, or extra living space, since an uninsulated door makes it hard to keep that room comfortable in cold winters and humid summers.

Insulated doors are rated by R-value, which measures how well the door resists heat transfer. A higher R-value means less energy loss through the door itself. Pairing an insulated door with good weatherstripping around the edges makes the biggest difference, since gaps at the sides and bottom let out just as much conditioned air as a poorly insulated panel would.

Our team can walk you through R-value options and help you pick the door that makes the most sense for how you use your garage and your home's layout.
