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.

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!

  • Covers 34.8 square feet

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.

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
