Masai4x4 sells a range of vehicle Sound Deadening and Heat and Cold Proofing Insulation sheets. Although we mainly sell Land Rover Defender products, these sheets can be used on a wide range of vehicles, and other applications. Sound Deadening & Insulation sheets improve the thermal efficiency of your vehicle - so warmer in winter, cooler in summer. They also reduce resonance, rattling, vibrations and the noise level from outside, i.e. from the road, tyres, engine, exhaust. In addition, they help to improve the sound quality of your audio system. Call us if you need assistance or are interested in our fitting services
