Review on 🔥 SmartSHIELD - 5mm 48''X 10ft SUV Van Car Truck RV Camper Heat Reflective Insulation Soundproofing Mat by Greg Horn

Good quality as is. I used it to insulate my bedroom windows. The insulation itself did not detach from the foil backing when cut for use. Note: Please note (I don't have it) as others have mentioned that the roll is not square. So drawing your cuts with a true right angle can save some time and discard parts, the roll is over or less than a full 4ft by 10ft, but the width can be 1/2 inch shorter or longer. A good product helps keep my air conditioned room cooler for longer.
