HushMat Complete Vehicle Insulation Kits

HushMats complete vehicle insulation kits serve two important functions: reducing thermal transfer into your interior, and reducing the noise level by up to 15 decibels. Your engine, headers, manifold and exhaust generate tremendous heat that transfers to the metal firewall and floor—forcing your A/C system to work harder to maintain a comfortable environment. HushMat auto heat shield is proven to lower this temperature by over 40 percent. At the same time, when you drive on the highway at 65 mph, most vehicles approach 80 to 90 decibels of noise. That's like a vacuum cleaner or garbage disposal running on your passenger seat. These insulation kits use a specially designed sound deadening material to deliver a more peaceful ride. Each kit is packaged specifically for your vehicle to provide 100 percent insulation coverage—no holes in the material and no puzzle pieces to assemble. Treat your firewall, doors, floor, tunnel, rear wheel wells, trunk floor, and roof with these HushMat barriers. Order the complete insulation kit designed for your specific vehicle. Additional details: * Reduces road noise and vibration, low-frequency noise from 0 to 1,000 Hz * Stay warmer in the winter and cooler in the summer; withstands ambient temps from -30 up to +550 degrees F * Lightweight and super flexible mats; less than 1/8 in. thick and 0.47 lbs. per sq. ft. * Adhesion is guaranteed; no alcohol or acetone wash needed; no tools required * Trims easily with standard razor knife or household scissors * Self-adhesive peel-and-stick; no glue required * Outperforms closest competitive brand by over 40 percent * OEM approved; meets or exceeds auto damping specs GMO 149M – General Motors; WSB-M5G58-A1 – Ford; and MS-CD 629 Type C – Chrysler
