What is Mass Loaded Vinyl:

Mass Loaded Vinyl adds mass to your walls, ceilings, floors, pipes...etc without compromising on space. It provides instant mass with damping to any location. By adding mass to an existing structure, soundproofing properties are significantly boosted, since soundwaves cannot vibrate the structure easily.

Our 1 lb. Mass Loaded Vinyl has an STC of 26 when hanging by itself. It is the same material and has the same fire rating as other brand names in the field, ensuring compliance with architectural specifications at our low price.

Reinforced MLV utilizes a high strength poly-fabric, combined with MLV to dramatically improve its durability and tear and hanging strength. It is made of commercial grade material that will not shrink, rot or cause metal corrosion and also features a strong resistance to adverse environmental conditions and UV light. It can be combined with a fiberglass decoupler to enhance acoustical performance.

Sample Applications:

  • 1 lb. Mass Loaded Vinyl is primarily recommended for use in floors, walls and ceilings.
  • Reinforced Mass Loaded Vinyl is great for hanging, to create an acoustical curtain. Can be applied with grommets and loop fasteners.

Installation Guide

Click to Print Mass Loaded Vinyl 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.


Figure 1- How to Install MLV

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 tape. {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.

Customers Questions and Answers

1) Tom: In regards to the reinforced 1 lb MLV, I like to use it outdoors attached to my wood fence to block a noisy pool pump. One side will be exposed to weather. Can this product be used outdoors, I am in California. Can either side be the "exposed" side to the weather? At a height of 6 ft, draping, can it be just attached at the top, or should it have intermediate and bottom attachments? Thanks Thanks.

Trademark Soundproofing Reply: Hi Tom. Yes this can be used outdoors with either one one or both sides exposed to the elements. The reinforced can be attached at the top only although it would help to add more attachments as well. Thank You.

2) Tevin K: Can this material (Reinforced MLV) be attached to the window for soundproofing? Are they too heavy to be attached?

Trademark Soundproofing Reply: Yes the reinforced will hold well if you use some type of mechanical fasteners.

3) Betty Lou H: Can this be used outdoors for an acoustical fence? Thank you for your reply.

Trademark Soundproofing Reply: Yes it can and is used that way.

4) Davorin Fundak: The web page specifies the thickness as 1/8 inch, however the spec sheet lists it at .086 inches. Which is it?

Trademark Soundproofing Reply: 1/8 of an inch - .125
