The DEI Boom Mat Under Carpet Sound Deadening Layer increases the quality of your ride by preventing unwanted noise from being transferred into your vehicles interior. In addition to its sound deadening properties, this two layer acoustic material provides superior insulation keeping vehicles cool in the heat of summer and warmer in cold temperature climates. The Under Carpet is made up of a top layer of flexible, one pound per square foot mass loaded barrier material and a bottom layer of high quality industrial acoustical marine grade foam. 

These combined materials offer the most ideal way to maintain a new car driving experience by eliminating squeaks, rattles, vibration and unwanted engine noise and heat. Easily added under carpet, on fire walls, or anywhere in the interior of a vehicle, the Under Carpet provides additional sound deadening or insulation where needed. For the ultimate experience in a quiet ride and interior comfort, Boom Mat recommends using Under Carpet over Boom Mat vibration damping materials. The Under Carpet can be mechanically fastened or tacked in place with Boom Mat Hi-Temp Spray Adhesive (# 010490) including vertical and overhead surfaces.
