Mass Loaded Vinyl, Soundproof Walls & Ceilings

MLV is already recognized as the most popular soundproofing product in the industry. MLV is the standard for soundproofing walls and ceiling. Available in 100 sq/ft rolls, MLV is easy to ship, simple to install, and readily available from our USA Distributors. There is no other product that has been used more for soundproofing in the US than MLV.

Mass loaded vinyl has several key benefits to improve the acoustic soundproofing of any wall; at only 1/8” thick there will be no change to window or door openings; with a different density and thickness than drywall, mlv helps to create a torturous path for vibration (noise); and when combined with standard fiberglass insulation and one layer of drywall you can immediately add 10+ STC points to your soundproof wall.

Mass Loaded Vinyl is Simple To Install

MLV will arrive in a 4’ x 25’ roll. Simply roll out and cut lengths to the height of the wall. Whether your stud spacing is 16” or 24” on center, our rolls are 48” so seams will occur on the studs (or you can overlap between studs)

Using a cap stapler, attach the first section to the wall, at the top, with 5 staples. Allow the section to gently drop to the bottom of wall, and attach vertically every 12” on every stud, the 5 times at the bottom.

Install next section as above, butt together on the stud, and double tape with foil tape. When you get to the end of the wall, cut last section to width and compete the install.

When completed, attach drywall to the studs, through mass loaded vinyl, and leave a 1/8” gap at the top, bottom and both ends of the wall. This gap will be filled with SilenSeal Acoustical Sealant after the entire room has been covered with drywall.

Mass Loaded Vinyl Stops Noise

Changing thicknesses and density, creating one large airspace, and decoupling surface from adjacent rigid surfaces are the three key elements when soundproofing a wall with MLV.

Because Mass Loaded Vinyl is thin in relation to drywall, is softer than drywall, and when installed is still flexible, it blocks noise in a completely different manner that drywall or plywood for that matter. When vibration (noise) tries to blast through a wall and all the materials are the same, it can easily transmit to the other side. But when vibration travels through drywall, then hits a flexible, thin material, it has to work much harder to get through; this added “work” uses up the vibration energy and thus absorbs the noise before it can get to the other side.

Changing thickness and density will block significantly more noise than adding more of the same. That is why MLV and drywall will outperform layers of drywall only.
