Overview of the TotalMass MLV Barrier 4 x 15 2 LB
The TotalMass MLV Barrier 4 x 15 2 LB is a mass loaded vinyl sheet designed for sound control applications in residential and specialty installations. This material is manufactured in the USA and is constructed as a nominal 1/4-inch (5mm) thick barrier weighing 2 pounds per square foot. Each roll measures 4 feet by 15 feet, providing a total coverage area of 60 square feet.
This barrier is described as a heavier version of mass loaded vinyl intended to help improve performance in lower frequencies. It is positioned as a preferred option over lighter 1-pound variants for use in home theaters and in applications involving exterior noise from vehicles. The material is manufactured new and is suitable for indoor or outdoor installation.
Technical Specifications
The sheet has a nominal thickness of 1/4 inch (5mm) and a density of 2 pounds per square foot. Product dimensions are listed as 48 x 8 x 8 inches when packaged, with an item weight of approximately 123 pounds. The color is black, and the roll size is specified as 4 feet by 15 feet.
The material is described as having a low odor that fades quickly. It does not fade in color when exposed to the elements and can be installed using nails, screws, or staples. Cutting can be performed with a razor, and seams may be taped using sheathing tape.
For detailed product specifications and sizing, refer to the official product listing.
Intended Applications
This mass loaded vinyl barrier is indicated for use in walls, ceilings, floors, over doors, around windows, fences, and around pipes and ductwork. It is also referenced for installation in vehicles, boats, and RVs. The material is generally used in assemblies that require improved isolation of lower-frequency noise such as traffic noise, home theaters, and recording studios.
By increasing mass within an assembly, the material is described as contributing to higher Sound Transmission Class ratings when incorporated into construction projects. It is intended to be layered within structural assemblies rather than used as a decorative finish surface.
Installation Characteristics
Installation guidance notes that the sheet can be cut easily with a razor. Fastening methods include staples, nails, or screws depending on the substrate. The seams may be taped with sheathing tape to maintain continuity across panels. The material may be used indoors or outdoors and is manufactured to withstand environmental exposure without fading.
Due to its 2-pound-per-square-foot density, the roll is heavy and may require planning during handling and placement. The flexibility of the material allows it to conform to surfaces within wall cavities or flooring assemblies.
Pros
- 2 pounds per square foot density for lower-frequency isolation applications
- Nominal 1/4-inch (5mm) thickness
- 60 square feet of coverage per roll
- Suitable for walls, ceilings, floors, doors, windows, and vehicle applications
- Manufactured in the USA
- Can be cut with a razor and installed with nails, screws, or staples
- Low initial odor that fades
- Color does not fade when exposed to the elements
Cons
- Heavy roll weight of approximately 123 pounds
- Seam taping required for continuous barrier coverage
- Adhesives are not specified as primary installation method
Performance Context
This barrier is described as being used in assemblies requiring improved isolation of lower frequencies, including traffic noise and home theater environments. It is also identified for use in recording studio settings where additional sound control is required.
When incorporated into construction assemblies, the added mass contributes to increased resistance to airborne sound transmission. The material is typically concealed behind drywall, under flooring underlayment, or within wall systems rather than left exposed.
