Quiet Ride Insulation NEW- AcoustiSHIELD Kits. Current technology in automotive design incorporates sound control systems and acoustic materials throughout the vehicle - from the engine bay to the trunk compartment. The purpose of these materials is to dampen, insulate and absorb the heat, cold and noise from the passenger compartment. In a typical luxury sedan, there is approximately 100 pounds of sound and heat control material incorporated into the interior body work of the vehicle. Its primary mission is to protect the passenger cabin from external noise. The ultimate goal is to create "sound proof box". By using the AcoustiSHIELD materials during the restoration or custom car building process you can soften the ride, deaden the noise, isolate the mechanical source of heat and control the forces of the external environment and all of these remedies are easily hidden behind upholstery panels.
