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

I am very happy with the insulating roll. It's of very high quality, the different layers provide excellent insulation, stay together when twisted and turned in my project, and are flexible enough to conform closely to 'unconventional' shapes. I used my roll to insulate the box under the central air conditioning fan which was originally made out of fiberglass panels 20 years ago and was in very bad shape causing a lot of air to leak out. I wrapped the insulation around the fiberglass box and secured it with silicone and a couple of screws with oversized washers - like new!
