Noise Barrier composite material combining the effects of the dB-Bloc barrier vinyl, a 1/4" backing foam and a 1" front facing foam. Ideal for lining enclosures to prevent noise transmission, reduce noise vibration and absorb trapped sound energy within the enclosure. Also available with an Aluminized Mylar facing to protect the material from moisture, heat, oil, abuse, sparks, and more. Pressure sensitive backing also optional for easy installation.

Applications
WARNING: Urethane foam, when exposed to heat or ignition sources may burn. Once ignited, urethane foams can burn rapidly, consuming a high rate of oxygen and releasing hazardous gases, toxic fumes and smoke. In an enclosed space, this may prove fatal. Consideration must be given to the flammability issue when using this product. Do not expose urethane foam to an atmosphere that will contaminate it, nor to ignition or hear sources that may cause it to burn.
