Mass Loaded Vinyl

Mass loaded vinyl (MLV) helps create sound-blocking assemblies to reduce airborne sound transmission for new or retrofit applications. These barriers are as heavy as lead but use no lead fillers. Dense, yet flexible, mass loaded vinyl improves sound transmission loss (STC) without losing valuable space. Use this product in both new or retrofit soundproofing construction. The standard offering is a non-reinforced barrier for use in average construction. Other configurations include materials for pipes and ducting, a transparent version and a heavy-duty version.>/p?

Mass loaded vinyl also appears as a layer in other products that we use to block sound. Often our customers combine these options with other materials in order to provide a complete sound-blocking solution.

AudioSeal^® Mass Loaded Vinyl (MLV) Soundproofing Barrier is the industry standard when it comes to mass loaded vinyl sound barriers. It helps reduce the amount of airborne sound transmitted through walls, floors, and ceilings. Depending on the site conditions, you can easily add mass to a multitude of construction assemblies. Typically used for soundproofing a wall in new construction, it can be stapled to the studs prior to hanging drywall. To retrofit to an existing wall, simply glue the barrier to the surface with a vinyl construction adhesive. Adding some large head roofing nails at the top will keep the barrier from sliding while the adhesive sets. Next, add another layer of drywall or other finish. Audioseal^® Sound Barrier is flexible and tear-resistant, yet it can easily be cut with a utility knife.

Sound also tends to transmit through pipes or ductwork. We have a couple of materials that can help combat this type of noise. AudioSeal^® Duct and Pipe Lag is a mass loaded vinyl sound barrier with a scrim foil face. Use pipe lag if your pipes or ducting have a decoupling fiberglass wrap. The reinforced, aluminum foil jacket provides a surface to accept matching lag tape.

If you are looking for a product to reduce noise from pipes or HVAC duct work, AudioSeal^® Duct and Pipe Wrap is perfect for you. This composite material consists of a foil-faced mass loaded vinyl, bonded to a layer of quilted acoustical fiberglass. Use AudioSeal^® Duct and Pipe Wrap to wrap ductwork and pipes to absorb sound, preventing it from entering or leaving. The foil-faced exterior serves as a protective jacket for both indoor and outdoor applications. Also, this provides an ideal surface to apply lag tape, making installation simple.

AudioSeal^® Reinforced Sound Barrier is a high-strength mass loaded vinyl that can be used when a durable, tear-resistant material is required for soundproofing. A high-strength polyester fabric backer makes this product versatile and heavy-duty. The improved durability prevents tearing when suspended vertically, like a curtain.  Because it can support its own weight, use it to create hanging barrier partitions. Additionally, AudioSeal^® Reinforced Sound Barrier is resistant to shrinking, rotting, adverse environmental conditions, and UV light.
