Heavy Layer Sheets are extensively used to provide Noise Vibration and Harshness (NVH) solutions for acoustic insulation and noise deadening applications in the automotive industry. These sheets are used in the insulation dash (between the engine and passenger compartments) along with the under layer in floor carpets, laminates, side trims, wheel arches and structural heat insulations, for the attenuation of engine noise and vibrations into the passenger compartment of the vehicle.
