Use the Cool-It Mat to battle excessive heat and noise that penetrates the driver compartment through firewalls and floorboards. Cool-It Mat is also perfect for use in doors, under hoods and above transmission housings. Cool-It Mat is composed of resin-bonded silica blanketing insulation sandwiched between a mylar facing and a foil facing. The highly reflective mylar reflects the heat away from surfaces, while the foil side is oriented away from the heat source to conduct any penetrating across its surface, providing the ultimate in heat protection. The silica blanketing is a dual-density composite which acts as the sound insulator. Cool-It Mat is easy to trim and it can be applied with the provided push-in fasteners or with Thermo-Tec's Heavy-Duty Spray Adhesive.
