Installation Guide

Click to Print Mass Loaded Vinyl Wall Installation Guide.

Mass Loaded Vinyl can be applied to walls, ceilings, floors and structures to create a sound barrier. Mass is a critical component in sound control and works by simply stopping sound from being able to vibrate the structure due to its heavy weight.

Please read through the installation guide before installing your MLV.


Figure 1- How to Install MLV  

Measure your wall from top to bottom. Deduct 1/8” – 1/4” from total height.

Unroll your MLV on the floor. With a utility knife, use a straight edge ruler to cut a square edge evenly through the MLV. {See Figure 1}

You do not need to cut through the material fully, once it is scored, it will come apart easily.

The MLV can also be cut with a heavy duty scissor.


Figure 1- How to Install MLV   For superior soundproofing results, use Acoustical Outlet Backer Putty Pad around all electrical outlets and other obstacles. {See Figure 2}


Figure 1- How to Install MLV  

This step requires the work of two people.

The MLV is applied over the fiberglass installation and beneath the sheetrock.

With the help of another, hold the MLV in place, starting at the upper corner of the wall. Ensure the sheet is straight

along the ceiling and is evenly spaced between the floor and ceiling {See Figure 3}

Fasteners: Any type of fastener will work (especially if the MLV will be covered with drywall) we suggest roofing nails or screws

with washers, however you can also use a pneumatic cap stapler.

Figure 1- How to Install MLV   Placement: Place fasteners every 8” along the top and bottom plate {See Figure 4} and down the length of the stud.



Be careful not to cover electrical outlets boxes. It is best to expose the outlets boxes as you install each length of MLV.

Find the electrical box in your wall and gently press the MLV against the box. Using a razor blade carefully cut the

opening along the edges of the box. Keep this hole tight as possible to the electrical box so that you maintain

a good seal. {See Figure 5}

Any extra gaps can be filled with Acoustical Caulk.

Continue as above until your entire wall or ceiling is covered in MLV.


Figure 1- How to Install MLV  

Where MLV seams fall on a stud, butt pieces against one another on the stud and fasten into place. You can add a strip of

PVC Tape on the seam. {See Figures 6 and 7}

We highly recommend that you end all MLV seams on a stud, as free hanging seams may come apart with time.

Figure 1- How to Install MLV    
Figure 1- How to Install MLV   Where MLV seams falls between studs, overlap pieces by 2" and tape seams with PVC Tape or similar tap. {See Figure 8}
Figure 1- How to Install MLV   Notch the ends to lay flat. {See Figure 9}

Once all strips of MLV have been applied, drywall can be installed above it and you can be ensured a sound-secure structure! For more information about MLV, contact us or call us at 845-352-3200.
