What is Mass Loaded Vinyl (MLV)?

Mass Loaded Vinyl, commonly known as MLV, is a heavy, vinyl sheeting material that is used to stop sound transmission. The weight of Noise Grabber™ MLV is the product of infusing vinyl with a proprietary blend of acoustical compounds, which gives MLV its high density while retaining flexibility. MLV has been used for sound deadening purposes dating back to the 1960s and is still considered to be one of the most effective sound-blocking materials on the market. Noise Grabber™ brand Mass Loaded Vinyl is a safe, non-toxic, odorless barrier designed to hang as a limp mass in a variety of sound deadening applications.

Noise Grabber™ Mass Loaded Vinyl is measured by weight, specifically in pounds. The general way that this is shown in pounds per square foot. For example, the 1 LB Noise Grabber™ brand MLV is 1 pound for every square foot of material. Therefore, a 4'x10' roll of Noise Grabber™ brand MLV would weigh 40 pounds. Square footage can be found by multiplying the width times the length (W x L), and then the weight can be found simply by multiplying the square feet to the pounds per square foot.

Square feet / Weight Formula: (W x L) x Weight per square foot = Total weight.

The weight of Noise Grabber™ MLV correlates directly with its thickness. A lighter MLV, such as the 1/2 LB Noise Grabber™ MLV , is not as thick as a heavier material such as the 2 LB Noise Grabber™ MLV. Since the material is produced to the weight per square foot, there may be some slight variation in the thickness of the MLV. The general thicknesses are:

1/2 LB Noise Grabber™ 0.75 LB Noise Grabber™ 1 LB Noise Grabber™ 1.5 LB Noise Grabber™ 2 LB Noise Grabber™
1/16” 3/32” 1/8” 3/16” 1/4”

STC Ratings Outside of how much they weigh, or the size, the different weights of Noise Grabber™ MLV have different degrees of sound blocking capabilities. The amount of sound blockage per weight is measured by the Sound Transmission Chart (STC) ratings, which you can read about in-depth here . STC ratings are compiled from laboratory testing of how much airborne sound is blocked by a material. All of the Noise Grabber™ brand MLV products have been laboratory tested and have verified proven results, backed by these STC ratings. There are several components that go into an STC rating, but there is a simple explanation of these ratings: The heavier the material, the more sound is absorbed into the material, the higher the sound transmission loss.

Mass Loaded Vinyl is a sound blocking sheet, meaning that it stops the transmission of sound waves. It does so in large part due to its weight and its proprietary sound-absorbing construction. Sound waves cause a vibration when they contact a surface, which then enlarges and expands as it transfers to the air outside of a room. Vibrations travel faster and easier through firm surfaces like floors and walls. A more malleable and dense material, such as Noise Grabber™ MLV, helps to reduce the transfer of sound. This is how Noise Grabber™ MLV works as a sound blocking barrier in several applications, as it offers a flexible, dense material, in addition to other firm, rigid materials such as walls, doors, ceilings, and other materials.

That brings us to another important characteristic of Noise Grabber™ brand Mass Loaded Vinyl: its flexibility. Even at its heavy weight, Noise Grabber™ MLV is very flexible and hangs limp instead of maintaining a rigid form like drywall or wood. This is done by taking a naturally viscoelastic material, PVC (polyvinyl chloride), and loading it with a proprietary blend of additives that create mass. A viscoelastic material will flow but will return to its original shape once the force moving them has been removed. This property, known as damping, helps Noise Grabber™ MLV lessen sound transfer. The flexibility of Noise Grabber™ MLV also allows it to be used in smaller or awkward shaped places where other sound reduction materials might not be a viable option. One such way is pipe lagging, where Noise Grabber™ MLV is wrapped around water and drainage pipes to reduce the noise level of moving water. The flexibility of Noise Grabber™ MLV allows it to be packaged in both roll and sheet form, which allows for easy movement and shortage.

Another positive feature of Mass Loaded Vinyl is its composition. High-grade MLV, like our Noise Grabber™ brand, is odorless and has a smooth finish. This allows it to be placed on or in walls without any fear of an ugly finish or bad smell. This is because Noise Grabber™ MLV is made largely of PVC plastic sheeting. As a plastic, the Noise Grabber™ MLV does not have an odor that you generally associate with black rubber construction materials. It also means it has a smooth, consistent finish that allows you to finish a project in any number of ways, including leaving it open to the room.

One of the best parts about Noise Grabber™ brand Mass Loaded Vinyl is its range of applications. Noise Grabber™ MLV is used across several areas of the soundproofing market. One of the biggest applications is in building construction. Thanks to its thin, flexible makeup, Noise Grabber™ MLV is fantastic for use in or on walls, on the ceiling, or on the floor. It can help reduce sound traveling through walls, between rooms, and used in the construction of a sound or music studios. Anywhere someone is building or remodeling, Noise Grabber™ brand Mass Loaded Vinyl provides a highly versatile noise reduction option. Another area of use for Noise Grabber™ MLV is in the automotive industry. Thanks in large part to its ability to stop any airborne sound, MLV is used in vehicles of all types to help with many different noises. From audio, vehicular, or road-noise, different sizes and weights of MLV can be used to help block out noise from your vehicle.

MLV Installation Installation is also straightforward, though it may require the use of two people due to the weight of the material. For building installation, such as home, apartment, or office, you can look at our Installation Walkthrough. For other applications, such as automotive, Noise Grabber™ Brand MLV can be installed with several different methods. One popular way is with a double-sided vinyl tape, which is common in automotive audio markets. Another way to install in a vehicle is with heavy-duty adhesive. For other kinds of installation, you can ask our experts about any tips they may have regarding your project.

One important thing to note when installing Noise Grabber™ MLV is that all seams of the material should be sealed for maximum performance. A good way to think about it is this: Anywhere air can move, so can sound. A good way to seal the seams is with tape or caulk, which you can view further here: Black Vinyl Acoustical Tape & Titebond® Acoustical Sealant. You can also check out our installation photos to get an idea of how Noise Grabber™ MLV can be installed. In any installation, make sure to contact a professional installation expert for any questions or concerns you may have.
