Our hood liners are made with our exclusive FATDAMP® Acoustical foam, 3/4" thick, with a reinforced aluminum foil facing and a 4 mil nominal acrylic PSA backing. Our foam is a acoustical grade open cell, flexible, modified poly ether polyurethane foam designed for optimal sound absorption over a broad frequency range. It has excellent resistance to heat, moisture and non aromatic petro chemicals. Our hood liners are larger than dynamat hood liners as well as more effective.
