The Boom Mat sound-deadening headliner kit for Jeep Wrangler JK hard tops is a pre-shaped peel-and-stick system that fits specific 2007–2010 4-door models and includes four white pieces. It reduces interior noise by about 3–4 decibels, lowers radiant heat from the roof and improves cabin acoustics. The open-cell polyurethane foam surface dresses the interior while adding thermal and acoustic insulation.
