Second, the Vinyl is impregnated with naturally occurring Barium Sulphate, a non toxic nature and high relative density substance. Mass Loaded Vinyl is comprised of 3 elements.įirst, vinyl is employed to provide the product with a high level of flexibility for ease of use. Sheets should be butted up against each other, or overlapped and taped using a a strong industrial tape. Mass Loaded Vinyl (MLV) can be glued to machinery housings, pump housings, boat or car structures to increase the mass and reduce sound transmission. Walls / ceilings / underfloors – the product should be tacked to studs / joists using tacks with large heads or incorporating a washer to minimize tear. The product contains a fabric scrim with an embossed face increasing tear resistance whilst maintaining high flexibility. MSDS | MONEY BACK GUARANTEE | 4kg/m2 Mass Loaded Vinyl Installation:Ĥkg/m2 Mass Loaded Vinyl is very easy to cut and install. 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 is also commonly used in a wide variety of other applications such as soundproofing cars, boats, pump housings, machinery rooms or other industrial applications. With an ultra thin profile of 2mm (approximately) and high acoustic performance of Rw 26*, 4kg/m2 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. Soundproofing, sound proofing, soundproof, home soundproofing, residential soundproofing, commercial soundproofing, soundproof flooring, Home theater soundproofing, studio soundproofing, garage soundproofing, room soundproofing, car soundproofing.4kg/m2 Mass Loaded Vinyl, or NuWave Base 4kg/m2, or just MLV, is a high performance, flexible soundproofing barrier from Thermotec Australia. Thanks for reading and learning, fo more information on soundproofing walls ceilings and floors, go to or call the pros at Soundproofing America at the number listed on the website. Now you have the option of soundproofing a wall or an entire room and not demoing the existing drywall. I know one thing, it is a lot less labor intensive than a full float using sound clips and f-channels. This system, according to the manufacturer, is as effective as a floated ceiling assembly using sound clips and furring channel. Now that the drywall is up, go ahead and caulk in the 1/8" gap around the perimeter of the drywall and that will become the resilient interface between the soundproofed wall or ceiling and the adjoining structures. Once again, as you are installing the new drywall, leave your 1/8" gap where the drywall does not contact the adjoining wall, ceiling or floors. I would recommend using 5/8" sheetrock or better yet 2 layers of 1/2" drywall with a bead of caulk between each layer. This will give the MLV a way to flex or move from side to side as well as allowing it to resonate inwards towards the stud or joist cavities. Now for a few more STC points, it is advisable to have a 1/8" gap where the foam backed MLV does not touch the edges of the adjoining walls, ceiling or floor. The next step is to tape the caulked seams, it is not necessary to tape the perimeter. You will also need to caulk the entire perimeter of the newly installed vinyl. The foam backing will face towards the existing drywall and all seams will be caulked liberally with an acoustical caulking. The foam backed MLV can be nailed or screwed directly to existing drywall, hitting the studs and joists as much as possible. That is why we recommend using the mass loaded vinyl with the standard or the premium foam backing. If the MLV is sandwiched between drywall, it is virtually impossible for it to move or resonate, so in essence you will only be experiencing a fraction of the vinyls full soundproofing potential. Basically regular mass loaded vinyl needs to be able to move or resonate as the sound tries to pass. There is a misconception about mass loaded vinyl being sandwiched between 2 layers of drywall. I will discuss one very effective method in this article. There are many ways to get effective soundproofing without removing the existing sheetrock. There are a lot of people out there who want to soundproof walls and ceilings, but do not want to demo (demolish) the existing drywall.
