Product Details

Masai 7mm 3-in-1 Sound Deadening with Foam Insulation Sheet

2mm Butyl + 5mm foam = 7mm total thickness (including aluminium foil sheet)

Sold by the sheet for your flexibility.

These particular sheets are 7mm 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, 5mm closed cell rubber foam, aluminium foil and strong adhesive with peel off backing. Soft and flexible.

If you want you can utilise this 7mm sheet and our other sheets in 2mm and 3mm 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 the roof, doors, footwells, wheel arches, side panels. Also helps with internal moisture control. As it is 7mm thick you may have an issue if trying to fit under certain carpeted areas and in certain areas behind door cards.

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

  • Improve the thermal efficiency of your vehicle - so warmer in winter, cooler in summer.
  • 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.

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

This 7mm 3-in-1 sheet (including foam) is ideal for lining vehicle roofs and doors, but can be used anywhere if clearance allows.

We also sell thinner 2mm and 3mm sheets, if you have certain areas that cannot accommodate 7mm sheet.
