Here you will find the lightest heat & sound rejecting insulation to use in the interior of your Chevy or any car to help against engine/header/summer heat & sound. It rejects heat and helps keep your cab quiet. This is not a generic bubble wrap like some might sell, this is a top notch product, extremely light-weight, and is very easy to install. All you need is some spray adhesive and some foil tape. We have 100% positive feedback on eBay but dealing with us directly on our website saves you money. We started out in the Corvette community but we expanded our reach as our insulation is very popular with classic muscle car owners and pro street drivers.
