Product Overview:

Description

Best Heat & Sound Damping Material

Eliminate road noise, floor pan vibration and exhaust heat from your vehicle! XMAT® creates the ultimate in acoustic and thermal protection for your muscle car, street rod, boat or RV. This multi-layer insulation includes an aluminum facing surface and high-tack butyl rubber membrane that block out unwanted noise and heat. Reduce noise by up to 19 decibels and interior temperatures by up to 30 degrees so you can focus on enjoying your ride. Because of its design, X-MAT can be used as door panel insulation, trunk sound blockers, exhaust sound deadening material and even hood insulation for automotive use. This package includes nine 18-inch by 31-inch mats, giving you nearly 35 square feet of coverage for your car. The sheets can also be cut and formed to be an exact fit for your vehicle.

Great Performance & Value

In the sound deadening showdown, it's no contest. Lab testing has shown that Eastwood's butyl sound deadener offers equivalent performance to other name-brand products while costing significantly less. While sound deadening material comes standard in modern cars, many restorers also add it to older vehicles so they can enjoy present-day comfort while retaining that classic look. You may also need it as part of body repair or an aftermarket upgrade. Whatever your reason for needing it, X-MAT offers a low-profile heat and sound reduction barrier to block out natural rattles, vibrations and warmth. See our product videos and reviews to learn more!

Features:

  • All-purpose X-Mat with three layers offering excellent temperature and sound reduction.
  • Butyl rubber membrane absorbs road and driveline noise while high-performance aluminum facing reduces engine and exhaust heat.
  • Easily cut and installed under carpets, inside doors, and around speaker boxes and firewalls so you can enjoy your ride in greater comfort.
  • Conforms effortlessly to complex interior contours of floors, door and side panels.
  • Withstands temperatures up to 350 degrees. Reduces heat as much as 30 degrees and sound by as much as 19dB.
  • Nine 18"x31" sheets included
  • Covers 34.8 square feet
  • Perfect for keeping your ride cool, quiet and comfortable year-round

Weight per sq. ft. is 12.8 oz.



Use Eastwood X-MAT® Car Heat & Sound Barriers for a comfortable driving experience in your restoration vehicle.

Rated 5 out of 5 by from X-MAT floorpan install I really like the Eastwood X-MAT. It seems like a quality product and it looks great too. When you install this product on contoured surfaces it'll take a little extra time to make it look like a proffesional install. Thanks Eastwood!

Rated 5 out of 5 by from I Deadened My Junk This x-mat is awesome, very effective, easy to use, looks good, thick and dense. It transformed my junky $1500 truck into a junky $1500 truck that doesn’t rattle, worth the money. It’s so thick I don’t even notice my rusty floorboards disappearing underneath them, win in my book.

Asked by: nick
First Paint Pre location. Peel backing and stick to surface, use hard roller to pressure it down. I will not peel off after being in place. This multi-layer insulation includes an aluminum facing surface and high-tack butyl rubber membrane that block out unwanted noise and heat.

Can this product be used over bedliner?

Asked by: Tsmeltz50
It could be used over a bed liner although it is not ridged and will tear if something heavy of dragged a crossed the surface. It is usually placed under a below a surface similar to a floor with carpet on top, as a buffer from noise.

I'm putting this in a 1996 Chevelle. The car has a channel in the floor pan that the wiring runs to the back. Should the wiring go underneath or on top of the X-Mat? Thanks.

Asked by: mas439
I would put any wiring above the Xmat.
