Use Thermo Tec Cool-It insulating mats to battle excessive heat and noise that penetrate the driver compartment through the firewalls and floorboards. They are suitable for use in doors, under hoods, and above transmission housings. The Cool-It mats are composed of resin-bonded silica blanketing insulation sandwiched between a mylar facing on one side and a foil facing on the other. The highly-reflective mylar reflects heat away from surfaces, while the foil side is orientated away from the heat source to conduct any penetrating heat across its surface thus providing the ultimate in heat protection. They are easy to trim and can be applied with the push-in fasteners provided or any weather strip adhesive.
