Construction & Design

The Boom Mat Headliner is constructed from high-quality open cell polyurethane foam, which is engineered to absorb sound waves and reduce noise transmission effectively. The foam is treated with a polymer surface finish that enhances durability and resistance to moisture and wear. This combination ensures the headliner maintains its performance over time, even under the demanding conditions typical of Jeep use.

The kit is precision-cut and pre-shaped to fit the contours of the Jeep Wrangler Unlimited JL hard top, ensuring a seamless fit that looks factory-installed. The peel-and-stick adhesive backing provides a secure bond without damaging the vehicle’s interior surfaces, allowing for straightforward installation and removal if necessary.

This reduction in ambient noise makes it easier to hold conversations and enjoy your vehicle’s audio system without the distraction of wind, road, and engine noise. The headliner also helps reduce heat buildup inside the cabin by reflecting radiant heat away from the roof, contributing to a more comfortable driving experience in hot weather.
