  • X-MAT® Sound Deadening 18x31 inches 34.8 sq ft
X-MAT® Sound Deadening 18x31 inches 34.8 sq ft is rated 3.6 out of 5 by 9.
Rated 1 out of 5 by from Not the good as Eastwood product it replaced I have used Eastwood Thermocoustic Barrier for years because it was identical to Dynamat Extreme but half the cost. This new XMat replaced the Thermocoustic Barrier product, but is very inferior. It is thinner and has far less adhesive qualities. I just pulled some up that was installed 3 months ago. Was barely stuck. Old product would have never come off. Price hasn't changed but quality has dropped. Both my hot rod shops will return to Dynamat and just pay the higher price. You do get what you pay for.

Rated 5 out of 5 by from Great Product!! I bought one box and its A LOT thicker then other products I've used, easy to install, did the interior of my 1953 Chevy in a couple of hours, if you want to do the doors and trunk you'll need (2) boxes. it REALLY makes a difference, lowers road noise and keeps the interior cool.

Rated 4 out of 5 by from Used on 1933 Chevy Eagle coup. I had issues with the way it was packed in the box it came in, it was folded into 3 parts. the creases do not come out, thus making the installation with ridges. Other than that it installed easy, and I will wait for the road test when summer comes, to see the difference it makes!

This is going to sound silly, but I have a very loud generator for my RV. Will this product help cut the sound if I enclose the generator with it? With exhaust of course.

Asked by: Ritz
I've used this type of noise barrier for the same exact purpose. It will reduce the noise (not completely eliminate) if you have an unlined generator box. Just take the time to use a good quality product and roller to ensure good adhesion to the top sides and floor.
