How to Insulate Garage Doors
Insulating a garage door will help reduce energy bills and protect items in your garage from harsh outdoor temperatures. Plus, garage door insulation can help soften street and outdoor noise. This project guide will show you how to insulate a garage door using relatively easy-to-install garage parts and insulation accessories.
1. Choosing the Right Insulation
2. Mark the Door
- Once you have the insulation and tools you need, you’re ready to start insulating a garage door. Start by planning the location of the fasteners.
- Make two marks on each door panel that are 12-inches in from each side and vertically centered.
3. Apply Double-Sided Tape
4. Attach Retainer Clips to Tape
- Remove the front side peel of the adhesive tape.
- Firmly press a retainer clip onto each piece of tape.
5. Measure Door Panels
- Measure each door panel.
- Note each individual panel’s measurements as they may not be the same size.
6. Cut Insulation to Size
- Cut a piece of insulation for each panel. Cut 1- to 2-inches longer than your door panel measurements.
- Peel off the excess insulation.
Safety: Many types of insulation, especially fiberglass insulation, are skin and eye irritants. Wear gloves and safety glasses to protect yourself when working with insulation.
7. Tuck Insulation into the Door Panels
- Per your previous measurements, tuck each insulation piece into its correct door panel with the vinyl side facing outward.
- If you chose an insulation with a reflective radiant barrier, the reflective side should also face outward.
