Bueno.
Donde vivo llegamos a temperaturas de 40-43 grados, y con este aislamiento en las ventanas logré que la temperatura bajara y la habitación no se calentara tanto. Lo compré principalmente para que uno de mis perros no sufra con el calor (es pastor alemán), y si he notado como pasa mejor noche.

Good Quality product
Easy to cut into the required lengths. Have used it on the inside of a garden shed but will have to wait till next week when the temp will be in the high 30's to see if it helps.. was delivered before due date.

What a difference
The amount of heat this keeps out is really amazing. Old house, old windows, poor insulation.... During the 'dog days' of summer even with the AC running non stop, it would get fairly warm then cool off as the sun set. I did some research and put some pipe insulation over the AC exhaust (portable) and grabbed a roll of this stuff after reviewing most of the brands available here this one seemed legit and the right size I needed as well. Glad I did. Now, there's a heat warning and it's noticably cool upstairs. Not like before. This stuff works!
