Construction & Design

The Boom Mat Headliner is constructed from open cell polyurethane foam, a material known for its excellent sound absorption and thermal insulation properties. This foam core is treated with a durable polymer surface layer that protects against wear and environmental factors, ensuring long-lasting performance. The kit is pre-cut and shaped to conform precisely to the contours of Jeep Wrangler hard tops, allowing for a seamless fit without the need for trimming or modification.

This thoughtful engineering ensures that the headliner not only reduces noise but also helps regulate cabin temperature by minimizing heat transfer through the roof, enhancing overall comfort inside the vehicle.

Performance & Sound

By reducing interior noise by 3 to 4 decibels, the DEI Boom Mat Headliner creates a noticeably quieter cabin environment. This reduction in ambient noise improves the clarity of conversations and enhances the listening experience for music and audio systems. The sound deadening properties also help reduce fatigue on longer drives by minimizing constant background noise, making your Jeep Wrangler more enjoyable for both driver and passengers.
