How to Install Noise Barrier – DIY

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.

Applying Noise Barrier

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.

Supporting the Fasteners

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.

Installation Preparation

Step 1

Measure the distance between the floor and ceiling. Subtract 1/8″ – 1/4″ from the measured length.

Step 2

Place the barrier on a flat surface and cut to desired length.

Step 3

Cut a square edge with a T-square and a utility knife.

Installing the Noise Barrier

Step 4

With two people holding up the material, place it in the top corners of the wall. Ensure the material is straight to the top to drape the wall evenly. Maintain the same gap along the floor and ceiling.
TIP: For quick installation, use a pneumatic cap stapler and fasten every 8” along the top plate and length of studs.

Step 5

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.

Step 6

Do not cover electrical boxes. Expose the boxes as you install each length of barrier. Find boxes by gently pressing barrier against the box. Using a razor blade knife cut an opening along the edge of the box. Keep this hole as tight as possible.
TIP: For superior sound isolation use pieces of barrier over electrical boxes.

Step 7

Continue with steps 1-6 until your entire wall or ceiling is covered.

Step 8

Install drywall over barrier, vertically or horizontally. Caulk all seams around the perimeter with acoustical sealant for optimal results. Mud drywall seams and finish wall as needed.
