Defender Sound Deadening and Heat Proofing

Sound Deadening and Insulation for Defenders

Our much-loved Land Rover Defenders can be on the noisy side at times; however, the good news is that this can be alleviated with Sound Deadening and Insulation sheets. There are no quick fixes to reduce road and engine noise and if you want the problem solved properly it requires a bit of work, but in the end, you’ll be happier with the vast improvement in the quality of the drive. Unwanted noise is created within most vehicles, especially the Land Rover Defender. This occurs across most parts of the vehicle, such as the doors, the engine bay etc. All of which need to be treated using several different methods to achieve worthwhile results.

Masai 3mm Premium Sound Deadening and Insulation Sheet

Sold by the sheet for your flexibility.

These particular sheets are 3mm thick and measure 350mm x 500mm (13.78" x 19.7"), which means 5.7 of these sheets cover one square metre.

Made with 3mm black Butyl, diamond embossed 200 micron aluminium foil and strong adhesive with peel off backing.

If you want you can utilise this 3mm sheet and our other sheets in 2mm and 7mm in different parts of your vehicle to suit requirements and budget

FITTING: Simply clean and degrease the areas to be covered, cut the sheets to the shapes required, peal off the protective sheet and apply in all the various places required to suit your needs. The removable backing sheet includes cutting gridlines. For purely sound-dampening you don't need to cover every square inch, the objective is to cover panel areas that can resonate or rattle.

APPLICATIONS: Ideal for insulating and removing unwanted sound in doors, bonnets, floor, footwells, roof, wheel arches, bulkhead, side panels, seatbox, rear tub.

Masai Sound Deadening and Insulation sheets provide solutions to multiple issues :

  • Reduce the resonance, rattles, vibration and noise level from outside, i.e. from the road, tyres, exhaust, engine.
  • Improve the sound quality produced by your audio device's speakers.
  • Improve the thermal efficiency of your vehicle - so warmer in winter, cooler in summer.

Fits all kinds of vehicles: cars, trucks, coaches, tractor cabs, buses, caravans, camper vans, etc.
