Eastwood Company 15841 X-MAT Heat & Sound Deadener Mats, Butyl/Aluminum

The Eastwood Company 15841 X-MAT is a multi-layer heat and sound deadening material that helps cut road noise, floor pan vibration and exhaust heat. It has an aluminum facing and a high-tack butyl rubber membrane, and it can be applied under carpet, inside door panels, on the inner firewall and in other areas of the vehicle.

• Withstands temperatures up to 350 degrees
• Low-profile material that conforms to complex floor, door and side panel contours
• Easy to cut and form for an exact fit

Sound deadening material is standard in modern cars, and many restorers add it to older vehicles for present-day comfort while keeping a classic look. It also suits body repair work and aftermarket upgrades. A quieter, cooler cabin puts less strain on the HVAC system and makes it easier to enjoy music or conversation, and the material also helps block extreme cold in winter.
