I just googled 'radiant barrier'. Everything I found basically says the same thing, and it relates to installation in different areas. I was interested in the rigid foam insulation you can get that has radiant barrier laminated on both sides, but that wasn't available where I am without a special order, and this simple stuff was the most cost effective alternative.

Actually, my garage door is not insulated, though I did use a couple of small strips of styrofoam as spacers to maintain the air space behind the barrier material. They claim the air space is required to get the full R value of the material.

I'll try to put up a picture tonight when I'm home.
