On the package it says that these blankets will reflect back 90% of body heat, challenge accepted. The west side of my apartment faces a large open blacktop parking lot that reflects a lot of heat straight into my windows, raising the temp in my apartment quickly in the afternoon. So I thought, "why not I have ten of them to play with?". With the blinds closed, trapped between the Mylar taped to the wall around the window, and the widows themselves. It reflected and trapped enough heat to melt the blinds! The temperature reached above 140 F (that is a far as the thermometer goes that I used) and made a huge difference in the room temperature. Now I know that is not the intended use of these but I would say that it is a dramatic test, non the less. I do not think they are reusable as the package says they are, as I was putting them up the aluminum started flaking off. Once you get a nic in them, they tear quite easily, but I have put these in all the emergency kits and the car, and yes I have ordered the thermal reflective window coating for the West facing windows. For the price, you simply cannot pass these up! Get them, you will find a use for them and they do reflect heat quite well!
