These dramatically decreased the temperature in our three car garage! Quite impressive I must say. Only advice is make sure you count how many tiles are on your door - other than that it’s some simple trimming and easily installed! These are a game changer for any garage that is used as a work or workout area.

This product does not disappoint. My garage is eight to ten degrees cooler now. Huge difference. The tape that arrives with the product works really well. No adhesión problems at all.

I can’t say it actually work it keeps my garage in the summertime about 15° cooler
