Mass Loaded Vinyl, or NuWave Base, or just MLV, is a high performance, flexible soundproofing barrier from Thermotec Australia, treated for UV radiation for fence insulation.

With an ultra thin profile of 2mm (approximately) and high acoustic performance of Rw 26*, Mass Loaded Vinyl is an excellent product to soundproof outdoor walls and fences at home.

Mass loaded Vinyl is also commonly used in a wide variety of other applications such as soundproofing cars, boats, pump housings, machinery rooms or other industrial applications.

Mass Loaded Vinyl (MLV) is dark grey or black in colour and Supplied in a roll, 5 meters long by 1350mm wide, weighing approximately 28kg.

Mass Loaded Vinyl Installation:

Mass Loaded Vinyl  is very easy to cut and install. The product contains a fabric scrim with an embossed face increasing  tear resistance whilst maintaining high flexibility.

External Walls / Fence – the product should be tacked to studs / joists using tacks with large heads or incorporating a washer to minimize tear. Gluing is also beneficial.

Mass Loaded Vinyl (MLV) can be glued to machinery housings, pump housings, boat or car structures to increase the mass and reduce sound transmission.

Sheets should be butted up against each other, or overlapped and taped using a a strong industrial tape.


Mass Loaded Vinyl for Fence Insulation Composition:

Mass Loaded Vinyl is comprised of 3 elements.

First, vinyl is employed to provide the product with a high level of flexibility for ease of use.

Second, the Vinyl is impregnated with naturally occurring Barium Sulphate, a non toxic nature and high relative density substance. It is this high relative density (mass) that gives Mass Loaded Vinyl such effective soundproofing capabilities.

Finally, the vinyl and barium mixture is added to a reinforcing scrim to increase the products tensile strength
