Introduction: Make Your Garage Energy Efficient. Easy Install of Radiant Barrier Insulation to Garage Doors.

I needed to "fix" a failed fiberglass insulation kit for garage doors from Owens Corning. Found the solution at one of the local big box home improvement stores with the Reflectix brand.

The panels in the failed fiberglass kit were only 22" wide and 60" long and needed a peel-n-stick plastic mount accessory centered to hold it in place. However it drooped and was unsightly.   

Step 1: Cleaning Preparation and Cutting Tools.

The radiant barrier rolls were 24" x 10' . Standard size of each panel row for the garage door. I used alcohol poured into a plastic spray bottle to clean the surface for better adhesion of the Scotch Super Adhesive 77 spay (or double-sided tape). Box cutters and scissors worked well for cutting slots for door hinges and excess material length.

Step 2: Clean Surface. Align. Spray Adhesive.

Spray and clean the panel surfaces. Unroll the radiant barrier and align. Spray both surfaces of the garage and insulation with adhesive. (An extra set of hands are best for this step but not required)  But since I did it solo, I sprayed and pressed a short unrolled length at a time, instead of pre-spraying the the whole surface sections and pressing the completely unrolled insulation in place.

Cut slots for hinges as the barrier insulation is applied and cut off any excess on the roll ends.

Step 3: Finish

Press along edges to ensure proper adhesion. Open the garage door to check proper alignment and panel separation.

Mine has been up for two-three years and it works well even in 100 plus temperature days. Nothing between the reflex-it and the panel.

Cool, literally :-)
What type of adhesive did you use? How is the adhesive holding up against the high temps?

I actually skipped adhesive. I cut mine tight enough that it stays in place by itself. It has survived so far. I bought an aerosol but realized that it might not need it so never tried. John

It has been three years now. How has this perfromed for you during the summer and winter months? Have any other problems with it now that it has been around awhile?

Does anyone one know what the cost per roll of the radiant heat rolls are. I have a double stall garage and want to do insulting, but need to get a budget together. Thanks

Home Depot has it on sale, today only for $15.50 24 in. x 4 ft. Radiant Barrier (10-pack)

Oh, so that's how you would do an insulation for a garage. I wonder though, would a garage door repair company be able to do something like that in the picture? It's something that I've been thinking about doing on my garage door.http://www.garbersofrichmond.com/Garage-Door-Services-Richmond-VA.html

Nice job. Very novel use of the product and lot easier than what I did with poly faced fiberglass blankets and Tyvek.

Great Project. I just finished mine. I used contact cement as the adhesive. It worked great. All hardware on each panel was removed [one at a time] , and re-installed over the insulation to hold it in place. Exception was the bottom corner where the tension cable attaches- I just trimmed around it.

I learned that I needed to leave a gap between the insulation on each panel [top/bottom] to avoid crushing it when the door opens.
