Product Details

Masai Sound Deadening and Insulation Sheet - 2mm thick

Sold by the sheet for your flexibility.

These particular sheets are 2mm thick and measure 350mm x 500mm (13.78" x 19.7"), which means 5.7 of these sheets cover one square metre.

Made with 2mm black Butyl, diamond embossed 100 micron aluminium foil and strong adhesive with peel off backing.

If you want you can utilise this 2mm sheet and our other sheets in 3mm 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.

Our Defender windows have been designed as replacements for the Land Rover Defender 90 and 110 and may fit other models – just call to discuss. They are easy to fit if you know a bit about DIY, you will need a drill and a rivet gun. A template is available as an optional extra. The size of the aperture needed is 1057mm x 427mm – which is the Land Rover standard size for Defender rear side windows. Fitting service also available – just call.

We manufacture to original Land Rover quality using original shape Land Rover aluminium profile and locks/catches. Our windows are made using E43R toughened safety glass – Omega Automotive has been manufacturing automotive safety glass and many other vehicle parts for many decades and supplies all around the World to various automotive firms.

Many old windows rattle, leak and are draughty – our replacement land rover defender windows will solve that – in addition if you order the tinted versions you will be reducing glare and reflecting some of the heat on a hot day. The tint is factory-prepared – the glass is actually tinted and not a stuck on film which can peel off – film is not simple to apply in any case as the glass has to be removed.
