Construction & Design

The Boom Mat Headliner Kit is crafted from high-quality open cell polyurethane foam, a material known for its excellent sound absorption and thermal insulation properties.

The peel-and-stick backing simplifies installation, allowing the foam to adhere securely to the hard top surface without the need for adhesives or fasteners. This design not only improves acoustic performance but also helps to reduce heat transfer from the roof, contributing to a more comfortable cabin environment in all weather conditions.
