Used on uninsulated garage door
My steel garage door was 105deg all last summer, and had ice on the inside in December. I cut these to fit inside each panel and kind of wiggled and smacked them into place. So far the door has only been 85 even in 92deg sun. Going to use between the posts in the rest of the barn before I finish framing it out for drywall.

easy to work with
I needed 4 sheets to complete the entire garage. at 1.5" thick, it was perfect for my garage doors. I chose to leave the foil side facing the garage for aesthetics. not sure if this will affect the insulation characteristics. hasn't been very hot so time will tell... I used a 4 foot straight edge, a square ruler, 2 clamps, tape measure and a straight blade... not a utility blade. Use the type of blade that you can snap off when you need a new piece. Those are more effective. With a little planning and organization it only took me 2 hours from star to clean up. Fairly easy project even for a novice.

This was the only insulation I could find that was 1.5 inches thick. It is perfect to fill in the voids between the framing of our pole building. I cut it with a heavy duty retractable knife. It cuts very cleanly in 2 passes. It has enough give to easily force it into the openings for a snug fit. Very easy to work with. Feels like it is very well made. I am looking forward to finishing the rest of the building's interior!

Use a electric carving knife to cut
This product worked great. The electric carving knife I used to cut the panels is the way to go. My garage and the rooms above it are noticably cooler. Less than $80 to do my double garage.
