If you look at the graph above you will see we only compare our material to other brands that use butyl rubber as a base. As you can see we provide the thickest material, most square feet & the lowest price compared to top brands. Brands that use asphalt like FatMat, Sound Destroyer, & Rattle Trap sacrifice quality to cut costs. These brands are not even in the same league as major brands, so we dont even include them in our comparison.

Thickness matters just like with wire. With Wire you are paying for the copper inside and with Sound Damping you are paying for the thickness of the rubber. The more material the better the damping factor. You would have to apply up to 3 layers of some of our competitors material to equal one layer of ours.

So why does it matter what type of material your sound damping mat is made from? Sound damping material is broken down into two materials. Butyl Rubber and Asphalt based mixes.

If you look closely most of the cheaper brands use asphalt based material which in the long term will not hold together as well as rubber butyl and it also has a foul smell that will never leave your vehicle. On the other hand rubber butyl leaves no trace of odor and has better elastic properties to extend durability. Besides who wants their vehicle to smell like a road construction project?

You wouldn't dump this in your interior would you?

Only the best belongs in your vehicle!

If your trunk is rattlin more than its bumpin then you might want to check out a Sound Barrier trunk kit to solve your problem. This kit is specifically designed to eliminate panel and trim vibrations that can drown out your subwoofers. Not to mention the embarrassment of the hum and clatter of your trunk as youre trying to show off your system to the car next to you. The kit includes (5) 18x32 sound damping sheets of material that allows you to cover the trunk side walls, floor and the trunk lid.

The material features a peel and stick design which allows for a simple yet effective installation that is guaranteed to stay in place regardless if it is exposed to the extreme winter chill or summer scorching heat. The material is a butyl rubber based compound and not the cheap asphalt terrible smelling based material found in many other sound damping brands.

This material also features an aluminum backed front which features the Audio Barrier logo stamped onto it. The purpose of the aluminum is to allow for both heat dissipation and to help keep the material properly held and formed into place. The most important stand out feature is the material is 1.78 mm which compared to other brands is up to three times as thick as our competitors! In simpler terms the thicker the material the quieter and cooler the ride!
