    • Works well, easy to use.
Color: Black
Pretty solid, the process was simple to apply the foam to my garage door. The double sided tape was a bit tricky to use. But overall id say this is solid.

    • Great for Orlando heat!
Color: White
Perfect for Florida heat. I added it to my garage as the sun beats down during the day in that direction and it decreased the heat immensely. I want to say 5-10 degrees easily. That might not sound like a lot but when you work in the garage it actually is. It was simple to cut, simple to install, and the quality appears to be good. I recommend ... show more

    • SmartGarage insulation
Color: Reflective / Reflective
This SmartGARAGE reflective garage door insulation kit exceeded my expectations. The quality of the materials is outstanding, and it’s clear from the start that this is a well-designed product. Installation was quick and straightforward, thanks to the clear instructions and included accessories. Once installed, the temperature difference in the garage is noticeable. It helps keep the space cooler during hot days and more stable overall, which also contributes to energy savings. Additionally, the reflective finish gives it a clean and professional look. This is definitely a highly recommended investment for anyone looking to improve the efficiency and comfort of their garage. ... show more

    • Looks good but not worth the price
Color: Black
This shows mutiple garages and I had to buy two for it to fit 2 car garage. Too expensive and temp in garage is maybe 5 degrees cooler than outside.

    • Looks easy to do yourself.
Color: White
I purchased this product and never opened the box. I’m sure this would be perfect if my house had morning sun. There is a small opening on the side of box that allows you to see the insulation. Now that summer temperatures are starting I really don’t think this will work for my garage. Door faces west and it gets hot! I found another garage door kit that looks easy to install, and is 1” thick. I won’t need to adjust door very much with the added weight according to neighbors and Home Depot. ... show more

Easy install. Keeps heat out from direct sunlight hitting the door. It looks very nice on the door too. I used 2 boxes to cover a standard 2 car garage door.
