DEI XL Damping Material 12.5in x 24in x 4mm

DEI is well-known for making parts that help manage heat and sound in vehicles. This Boom Mat XL damping material is a great example, designed to quiet down your interior by stopping panels from vibrating and making noise. It uses a thick, 4mm layer of asphalt-free butyl rubber bonded to a stiff aluminum top skin. This combination effectively traps and dampens unwanted noise, making your cabin a more comfortable place to be.

What's neat about this material is that it only needs about 25-50% coverage to do its job, which saves you weight, material cost, and installation time. It adheres well to almost any interior surface, whether it's flat, vertical, or even overhead, and it holds up in extreme temperatures. The material comes on an easy-peel plastic liner, so you don't have to worry about paper backing tearing. This can also help improve your stereo's sound by reducing background noise.

You get two sheets, each measuring 12.5 inches by 24 inches, for a total of 4.2 square feet of coverage. It's a solid option for controlling noise and dampening vibrations as a first layer in your sound deadening project.
