We designed Damplifier to compete against the best and most popular constraint layer deadeners (CLD) the industry has to offer while both weighing AND costing less! With a weight of .35 lbs. per square foot and a 6.5 mil thick foil constraint layer, this self adhesive CLD vibration damper helps insure a cool and quiet ride by killing structure borne vibrations, noise, and heat, while saving weight, money, and in some cases time and effort as well; Thanks to the high temperature & high rubber content butyl adhesive, you'll never have to worry about this automotive insulation falling off, peeling, or melting. Damplifier is the perfect automotive sound deadener for every area of the vehicle. Simply cut, peel and stick this foil backed vibration damper under your carpet and upholstery to get better sound deadening results than any other product in its class!
