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 2 lb. Mass Loaded Vinyl has an STC of 31 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. With all the new soundproofing products available, Mass Loaded Vinyl is still a favorite among studio builders and contractors.

Sample Applications

  • This MLV is an ideal choice to lay down on floors, under carpet or hardwood

  • Can be used on outdoor fences as a soundproof barrier.

  • Due to its  heavy weight and thickness, it might be difficult to install on ceilings, or even walls. For those applications, you can use 1 lb. Mass Loaded Vinyl and use a double layer.

  • MLV is the sound control material of choice to use under carpet when a noise problem exists between a floor/ceiling in an existing home and adding drywall with Green Glue to the ceiling underneath is not an option.

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.  

STEP 1: MEASURE AND TRIM 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.

STEP 2: PREPARE YOUR WALL FOR INSTALLATION

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}

STEP 3: APPLYING YOUR MLV

 
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.

STEP 4: EXPOSE YOUR ELECTRICAL OUTLET BOXES

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.

STEP 5: FINISH YOUR SEAMS

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.

Comments about 2LB Mass Loaded Vinyl, 4' x 25', 100 Square Ft.:
It's great that it's thin and doesn't shrink your space much. Make sure you have someone to help you put it up. I sandwiched the MLV between 2 sheets of sheetrock. Using a staple gun for the MLV was a great idea.
Bottom Line Yes, I would recommend this to a friend

Customers Questions and Answers

1) jim : Can this material be used externally (as a sound barrier around my pool area). Do you stock the 2 lb in transparent or translucent material?

Trademark Soundproofing Reply:

Hi Jim, Yes this can and is used in an outdoor environment. We only stock the black color.

2) Chris H: Does your warranty allow for CARPET TILES to be installed on this product?

Trademark Soundproofing Reply: Hi Chris, we do not have such a warranty. I would suggest you test a section first.

3) Jim: how do you install this product over a plywood sub-floor

Trademark Soundproofing Reply: Hi Jim. It gets rolled out and laid down a few nails will keep it in place.

4) Harold M: We are interested to find out if the material can be: 1) Painted 2) If a spray-applied acoustical/thermal insulation like cellulose will bond to the material.

Trademark Soundproofing Reply:

Hi Harold. We do not recommend painting it, however we have heard feedback from contractors who have been successful using Sherwin Williams XIM primer. They wil most probably not bond properly. We do offer a MLV with fiberglass bonded to it.
