Thermotec NuWave Base Mass Loaded Vinyl, is a high density, high performance, ultra thin Acoustic Insulation made from barium loaded vinyl. The flexible construction creates a very versatile acoustic insulation product that lends itself to use in walls, under timber floors and many industrial applications such as cars, boats, machinery housings etc. Because the product is impregnated with barium, it has a very high density which makes it an extremely effective sound barrier. Acoustic performance =Rw26*. *Rw rating is a single number quantity summarizing 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.

The NuWave range of high performance barriers is based on high density, limp mass polmers to take the energy out of sound waves right across the hearing frequency spectrum. NuWave barriers are flexible, inexpensive and will control unwanted noise from home theatre systems, aircraft noise, machinery noise, unwanted noise through walls and floors, office ceilings and other types or airborne noise. When noise and sound transmission needs to be effectively controlled, NuWave Noise Barriers provide the solution to ensure that building standards are complied with, and that noise levels are effectively reduced. NuWave noise barriers are also manufactured in various composite products such as high performance carpet underlays, heavy transport cabin insulation, plant room noise control, and waste pipe.

Mass Loaded Vinyl-Australian Made

Thermotec Australia developed an extra HEAVY DUTY, high performance, flexible soundproofing barrier called NuWave Base or Mass Loaded Vinyl.

With an ultra thin profile of 4 mm (approximately) and high acoustic performance of Rw 30*, Mass Loaded Vinyl is an excellent product to soundproof walls, timber floors and ceiling spaces in residential homes & is particularly suitable for office partitions in commercial buildings.

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

MLV is dark grey or black in colour and Supplied in a roll.

Mass Loaded Vinyl Installation:

MLV  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 / underfloors – We propose the product be tacked to studs / joists using tacks with large heads or incorporating a washer to minimize tear. Gluing is also beneficial.

To increase the mass and reduce sound transmission, glue the Mass LoadedVinyl to a machinery housing, pump housing, boat or car structures.

We recommend the sheets butted up against each other, or overlapped and taped using a a strong industrial tape.

MLV Composition:

Mass Loaded Vinyl Australia comprises of 3 elements.

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

Second, the Vinyl 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 LoadedVinyl such effective soundproofing capabilities.

Lastly, the vinyl and barium mixture added to a reinforcing scrim to increase the products tensile strength.

Wall & Ceiling Predictions

BCA F5.5 (a) Sound insulation rating of walls—A wall in a Class 2 or 3 building must

(I) have an Rw + Ctr (airborne) not less than 50, if it separates sole-occupancy units; and
(II) have an Rw (airborne) not less than 50, if it separates a sole-occupancy unit from a plant room, liftshaft, stairway, public corridor, public lobby or the like, or parts of a different classification
(c) A wall in a Class 9c aged care building must have an Rw not less than 45 if it separates(I) a sole-occupancy unit;or
(II) a sole-occupancy unit from a plant room or liftshaft
