Mass Loaded Vinyl (MLV) is a high performance, flexible soundproofing barrier suitable for applications requiring a high level of soundproofing.
With an ultra thin profile between 1mm to 4mm (approximately) and high acoustic performance of between Rw 26* & Rw30, Mass Loaded Vinyl is an excellent product to soundproof walls and ceiling spaces in residential homes & is particularly suitable for office partitions in commercial buildings.
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 roll form, 1350mm wide by either 3 meters or 5 meter length.
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.
Walls / ceilings / under floors – 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 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
*Rw rating is a single number quantity summarising the transmission loss of a material over the frequency range from 100Hz to 3.15 kHz under AS/NZS 1276.1:1999. Independent test reports available.
