I questioned the Product at first. Then I did my homework on radiant heat. My thin wall aluminum garage door was same temperature on the outside verses inside. It’s March 1st and 91 degrees . After Installing the Smart garage product The outside of the door tested at 135 degrees and the inside tested 99.8😊 The garage has maintained a 75degree inside temperature all day maintaining a 16 degree difference. Easy install just take your time and measure Twice😂 Rob Harris Goodyear ... show more

    • Outstanding Reflective Garage Door Insulation Kit
Color: Reflective / Reflective
I used this Reflective Garage Door Insulation Kit and couldn't be happier. It was easy to measure and cut. The double-back tape was easy to apply and had no problem with it sticking. The backing can get frustrating to get off but that's true with any double-back tape. It actually reflects the heat; you can feel it on your hand. The core is a foam and not just bubble wrap. All in all, this is a great product. ... show more

    • HOT GARAGE - BUY THIS NOW!!! Your Electricity Bill will thank you!
Color: Reflective / Reflective
If I could give this item 10 stars I would. We live in Texas and our house receives direct evening sun for appx 4 hours. Our garage doors (hurricane doors) were so hot you could not even touch them. Our garage temperature sat in the 110-120's on a hot summer day. This not only effected the garage but the rooms above the garage - the humidity levels were hard to control. We added this SmartGarage Door kit to our double door and single door (3 boxes were needed) and we could not be more thrilled with the results. Our garage has been staying around 85-90 degrees on the hottest summer days now. That might sound awful but in reality it is a great improvement. We have seen a reduction in our humidity in the upstairs rooms along with a reduction in our electricity bill. Installation was easy - measure, put adhesive on the insulation and install on the door panels. Took us around an hour to install on our doors. I have been so pleased with the results many of our neighbors have also purchased and installed and say what a relief they are feeling. We don't get super cold winters typically but excited to see if during the cold weather we get if our garage maintains a comfortable temperature as well. ... show more

We have a three car garage. I was not sure if this product will fit on our garage doors so I only bought one to give it a try. When it arrived, I was able to install it on a single garage door by myself within an hour. Installation was super easy, I measured the length of the garage door panel and cut out the sheets using the provided box cutter. Then I put the provided double side tape on the door panel, put the sheet in place then remove the tape back cover and fix the sheet on the door panel. After the single door was covered, I measured the temperature on the double door and single door and was happy to see at least a twenty degrees (F) difference. I immediately ordered another two sets to cover the double door. ... show more

    • Good company
Color: White
The company stands by their product. In the short time it's been installed, it seems to be insulating from the cold. I purchased two packages to cover my standard two car garage door. I was able to get a large portion of the door covered, but was 4 panels short. I measured and cut precisely to not have excess. The rolls were both short by two panels worth. The company was ready to work with and made it right. ... show more
