Garage Door Reflective Insulation Kit: 16 Double Bubble Insulation Panels, 24 x 48 Inch Aluminum Radiant Barrier with Heavy-Duty Tape

I was skeptical at how good this was going to work for the added thermal protection. I was blown away at the performance. Installation was fairly easy. I used a sharp pair of cutting scissors instead of the box cutter that was supplied. I marked and measured all the panels and cut the panels to fit each section. This process was slow but I think I had all the pieces cut and installed in a few hours. I took my time and worked over a few days. The following weekend we had a dramatic drop in temperature. I used a laser temp gun and acquired readings on several different locations of the garage door. I went from high to low, with the panel installed and without. I was averaging about 15 to 20 degree difference! I would get a reading of 70 on the panel and about 50 on the metal garage door. I went to the local fabric store and picked up some cheap black felt on sale and cut them out to go over the windows in the top rack of the garage door. With the felt installed and the panels in place, you can't tell from the outside. I highly recommend this product to anyone who is considering it. It has significantly raised the temperature in my garage to make it bearable during the cold winter. I haven't even thought about adding a heater as it is manageable without one so far.

Easy to install, the tape was a little challenging, ,but with patience it works well. With Nevada heat, I felt great improvement, in addition, to my solar garage fan. Love, love, it. The red picture shows 106F, then could not read anymore. Message given, (“too hot)

Product works well, but might need additional good double sided tape. I cleaned the door thoroughly first, like instructed, but the insulation still came off after a relatively short period. Used good double sided tape and its fine. Does reduce heat and cold temps in garage.

I live in the Central Valley of California, where it gets to 107 for about 30 days in the summer. This product has been installed for less than a week and you can feel an amazing difference in the temperature of the garage and the walls that are connected to the garage. My garage door opens to my kitchen and you can feel a huge temperature difference.Should have bought this stuff years ago.Garage door is light aluminum and painted.Two different panel widths that were easy to cut and fit.The width was perfect to fit into the grooves by hand without tape. The lengths were 54 and 44 with a simple cut to fit.Buy It!

Product received as described and delivered within specified time. The installation instructions were simple and easy to follow. I’ve noticed a significant garage heat reduction from this awful Texas heat.

The double sided tape does not hold onto hot surface well. Some of the insulation starts to come off after 2 days. I live in AZ and you can imagine how hot the garage door can get. At the time, the surface temperature was around 97 degrees.Also, it's not perfectly a right angle.

We put this on the inside of our garage doors since we turned it into a workout room. Cooled it overall by a good amount and helps keep the AC unit doing it's job. Easy material to cut and tape up.

The glue tape is not good , need to replace it. Pls help.
