How to Install Mass Loaded Vinyl Noise Barrier For Walls and Ceilings

Flexible non-reinforced noise barrier is a 1lb per square foot mass loaded vinyl. With an STC of up to 32, it is used to reduce sound transmission through ceilings and walls. Most commonly used in residential/multi-family and some commercial applications. Many people think installing noise barrier is complicated. However, with the proper tools and know-how, installation can be completed with ease. The following guide will help people install noise barrier on their own.

When looking to reduce the transmission of noise with a barrier it is a rule of thumb that the barrier should be as close to the noise source as possible and be double the height and length of the noise source. This is particular relevant in exterior applications such as construction and outdoor sport facilities. If you can see a loud noise source, chances are you can hear it. If your barrier is the same height and width of a noise source, that noise will work its way around and you’ll still be able to hear it.

Noise Barrier can be installed over existing wall or ceiling surfaces or directly to wood/metal framing. Options for framing include:

• Loosely taught on framing
• Attached to framing
• Between layers of drywall, plywood, plaster, etc.

If installing on bare stud walls or ceiling joists, install parallel to framing (vertically on wall studs). Because of the stud or joist behind the seams, you can put pressure on them. If you are putting barrier on existing walls, find the studs/joists and mark them. The final result should be a flat application of the material.

Using the right fasteners helps reduce the chances of the barrier tearing under its own weight. A wide head fastener, such as a cap stapler, screws with plastic washers, or roofing nails assists greatly with weight distribution. Start with several fasteners at the start of the roll before allowing to hang. Do not rely on drywall alone to support the barrier. All fasteners must be affixed directly into the frame, flush with the structure.

For 16” on center (o.c.) framing, hammer the nail and washer through barrier every 24” o.c. along the top plate length of each stud. For 24” o.c. framing, hammer another nail into the top and bottom plate between each stud.
