The DEI Boom Mat Sound Deadening Headliner Kit addresses these issues directly with a precision-cut solution. This 13-piece kit is engineered to reduce cabin noise levels by 3 to 4 decibels, significantly improving interior acoustics for easier conversation and better audio performance.

The kit features a peel-and-stick design for a straightforward installation without the need for specialized tools. Each piece is constructed from high-quality open-cell polyurethane foam finished with a durable polymer surface treatment that provides a factory-style appearance. In addition to sound dampening, the material provides a thermal barrier to reduce radiant heat transfer from the roof, keeping the cabin more comfortable in extreme weather conditions.
