How Do I Insulate a Garage Door?
If you’re asking, “Should I insulate my garage door?” the answer is simple: yes. Especially in Portland, where temperatures can swing and energy costs climb fast. An uninsulated garage door is basically a giant hole in your home’s thermal barrier.
Why Insulate a Garage Door?
Your garage isn’t just a place to park your car. It’s often a workshop, a home gym, or extra storage. When the garage door isn’t insulated, it turns the whole space into a temperature trap freezing in the winter, sweltering in the summer.
Insulation cuts energy loss, making your home more efficient. It reduces outside noise, too, so you’re not hearing every garbage truck or lawn mower. It also helps protect anything you store inside, like tools, workout equipment, or that extra fridge. And long-term? It can add value to your home.
What You’ll Need
Before you dive in, gather a few essentials. Start with a garage door insulation kit these usually come with pre-cut panels designed for standard 8- or 16-panel doors. You’ll also need a utility knife, tape measure, straight edge, double-sided tape or adhesive, and a pair of gloves. Some insulation materials can irritate your skin, so don’t skip those.
For best results, go with polystyrene foam board or a reflective radiant barrier. These materials deliver the most insulation without adding too much weight to your door.
Step-by-Step: How to Insulate Your Garage Door
1. Clean the Door
Start fresh. Wipe each panel down with a clean cloth to remove dust, grease, and grime. Adhesive won’t stick well to a dirty surface.
2. Measure Each Panel
Garage door panels aren’t always uniform. Grab a tape measure and jot down the height and width of each panel cavity. Don’t assume they’re all the same measure each one.
3. Cut the Insulation to Size
Using your measurements, cut the insulation using a utility knife and a straight edge. A snug fit is key here. Tight insulation stays in place better and performs more effectively.
4. Attach the Insulation
Apply double-sided tape or adhesive to the back of each panel. Press the insulation in firmly. It should sit flush with the panel no air gaps, no bowing out.
5. Seal the Edges (Optional but Smart)
Want to go the extra mile? Use foil tape to seal the edges. This keeps the insulation locked in and helps prevent air leaks around the perimeter.
6. Check the Balance
Insulating your garage door adds weight. Test your garage door opener to make sure it’s still operating smoothly. If the door feels heavier or your opener strains, you may need to adjust spring tension, or call us at PDX Garage Door to handle that safely.
