B-Quiet Extreme Sound Deadener 12 sqft. roll Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

B-Quiet Extreme is a 1.15mm (45mil) thick composite mat which consists of rubberized asphalt with an aluminum constraining layer. When the paper backing is removed the supercharged adhesive surface forms an incredible bond to ensure optimum deadening performance. Thanks to the aluminum constraining layer and superior adhesive, it can be used on floors, doors, roofs and trunks, but not under hood. B-Quiet Extreme weighs 0.30lb/sq. ft., comes in 1 foot wide rolls and is available in two sizes: 12 and 50 sq. ft. rolls. OUR SUGGESTION FOR YOUR BEST RESULTS: We suggest B-Quiet Extreme or Ultimate throughout the vehicle to control structural borne noises, such as rattles, resonances, vibrations and also to slow the propogation of road/engine/exhaust noise into the cabin. For even better reduction of road/engine/exhaust noise, we would suggest a layer of Vcomp/LComp over top of the Extreme/Ultimate on the floor, lower interior firewall and rear cab wall to absorb and block airborne noises. We recommend 100 sq. ft. Extreme/Ultimate and optionally 30 to 40 sq. ft. of Vcomp/LComp for your vehicle. You also might consider a sheet of Hliner for under the hood to further reduce engine noise levels inside the cabin.
