Review on Zirgo 193210 UltraMat Barrier Square by Edwin White

They are suitable for a variety of things! I used them on walls, windows, cars, whatever. They also reflect the sunlight! The temperature difference is clearly visible only by touch. Be sure to buy! For example, I used masking tape to attach them to the outside of the sliding patio door and it made my living room 15 degrees cooler! It reflected the sun and provided excellent insulation. Happy to buy again!
