Car insulation is the lightest & most effective thermal sound deadening insulation in the world! Our made in the USA product is an EXTREMELY light-weight sound deadener & thermal barrier that creates a quiet, comfortable, and efficient interior for any vehicle. Car Insulation will keep you cool in the summer by reflecting unwanted engine, header, exhaust, & summer heat but also keep you warm in the winter! It is extremely flexible & very easy to cut, handle, and install. It is used by professional race teams, auto restoration shops, & thousands of customers around the world. It's universal and can be installed in any vehicle in the entire interior including even the headliner & doors.

Car insulation is 1/4" thick overall and weighs 0.04lbs per Sqft so every 25Sqft roll of material weighs only 1.00lb! This is NOT a Jute or Butyl based product. It has a closed cell polyethylene core with a fiber reinforcement on both size to prevent long-term crushing.

This can be used in ANY VEHICLE to insulate & sound proof your entire interior: floor pan, doors, under carpet/seats, headliner/roof, trunk, trunk lids, and firewall (interior side). Car insulation is used in many automotive applications: muscle cars, hot rods, corvettes, imports, tuners, street rods, rat rods, classic cars, race cars, stock cars, old vintage cars, pickups, trucks, low riders, etc. We even have customers who use it in their airplane, SUV, RV, limousine, camper, boat, motor home, or school bus.

Installation - There is NO ADHESIVE on our product but you have several easy options for installing which include spray adhesive, foil tape, double sided tape, glue, etc. Spray adhesive & foil tape in combination work best for installation. Foil tape is optional to use with spray adhesive but helps you achieve the best thermal & vapor barrier. For the ultimate install - double layer it in your vehicle!

We have 100+ sizes to choose from so please check the drop down list!
