How to Insulate Garage Doors
Time Required: Over 1 day
Insulating your garage door will help reduce energy bills and protect items in your garage from harsh outdoor temperatures.
This project guide will show you how to insulate a garage and weatherize the space using a relatively easy-to-install garage insulation kit. Insulation kits are the quickest way to complete this project as they include insulation and most of the necessary anchors.
- Choose which insulation you'll use for this project by considering what type of garage door you have.
- Wooden garage doors need rigid insulation like foam board, while metal garage doors can work with any type of insulation.
Cut a piece of insulation for each panel, cutting 1 to 2 inches longer than your measurements. Peel off the excess insulation.
Tip: Wear gloves and safety glasses to protect yourself when working with fiberglass insulation.
- Push insulation flat against door and feel for retention clips.
- Slice ½-inch slits through the insulation above the retention clips and attach the front of the retention clips to the back pieces to secure the insulation panels.
