X-MAT® Sound Deadening 18x31 inches 34.8 SQ FT

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!

Customer Reviews

Rated 5 out of 5 by from Easy to work with and excellent results Very easy to work with. Easy to cut and shape, conforms to floorboards, firewall. etc. Changes the feel and sound of the interior, making the car feel more "solid". Also helps to keep out heat as well. Costs less than the big name brands and seems to work just as well.

Questions & Answers

Can carpet/pad be glued to the surface of the Xmat or does the carpet have to be loose-layed? If so, what kind of adhesives would be acceptable(3M spray adhesive, contact cement). Thanks

Asked by: stratcat
You can certainly apply carpet directly over the X-Mat. Any carpet adhesive such as 3Ms should work great.

Hi. The inside of my truck cab is sprayed with bedliner worried if this would stick or would I need different glue... thanks

Asked by: Big Dan
This product does not use a glue for mounting. It has a Butyl Rubber backing membrane that adheres to your surface when applied and rolled out. This product will stick well to the bed liner on the flat horizontal applications. For a vertical applications on the bed liner surface we would recommend a test area to check for proper adhesion.

Currently, my cab is completely stripped down... On a typical install, do things get bolted down on top of this insulation or do you cut the insulation around items that attach directly to the floor/firewall?

Asked by: crazy96863
In most Automotive applications Eastwoods Xmat is applied up to and around items that get bolted down to the floor or firewall. Should you bolt on top of the Xmat product such as seat installations you will need to re-torque the bolts a second time after the Xmat compresses.

will it stick to plastic? I would like to use it in place of the oem stuff that the mice like on the interior panels of my Cherokee.

Asked by: dverge
Yes! The X-mat will stick to plastic since it has a strong adhesive on the back side.

I have a jeep Cherokee. deleted the carpet. can i put this down then apply one of the bedliner type products over top of it?

Asked by: Hunter
The X mat is not meant to be painted over. Eastwood does offer a paintable heat and sound barrier that when dry will give the appearance of a bedlinen type of product. The item number is #15632zp. https://www.eastwood.com/heat-and-sound-barrier-coating-1-5-gallon-kit.html
