Overview
The TotalMass MLV Barrier 4 x 15 2 LB is a mass loaded vinyl sheet for sound control applications. It uses added mass within residential and specialty assemblies.
The barrier is designed to support lower-frequency isolation in home theaters, recording studios, and exterior vehicle-noise applications. Also, it supports indoor or outdoor installation across several structural surfaces. It works as a layered barrier within an assembly rather than a decorative finish.
Each roll measures 4 feet by 15 feet and covers 60 square feet. The nominal 1/4-inch thickness carries a density of 2 pounds per square foot.
Key takeaways
- The barrier uses a density of 2 pounds per square foot.
- Each roll measures 4 feet by 15 feet and covers 60 square feet.
- The nominal thickness is 1/4 inch, or 5mm.
- Supported locations include walls, ceilings, floors, doors, windows, fences, pipes, and ductwork.
- The material supports installation in vehicles, boats, and RVs.
- Fastening options include nails, screws, and staples.
What the product is designed to do
Mass loaded vinyl adds mass to a wall, ceiling, floor, or another structural assembly. In this application, the material supports resistance to airborne sound transmission.
The 2-pound mass loaded vinyl barrier targets assemblies that require improved lower-frequency isolation. Also, named applications include traffic noise, home theaters, and recording studios.
The sheet can cover broad surfaces or wrap smaller sound paths. For example, supported placements include doors, windows, pipes, and ductwork. These locations often form part of a larger wall, floor, ceiling, or enclosure system.
The barrier also supports specialty installations in vehicles, boats, and RVs. In addition, it can form part of indoor or outdoor projects requiring a flexible mass layer.
Materials, dimensions, and technical details
| Detail | Specification |

| Roll size | 4 feet by 15 feet |
| Coverage | 60 square feet |
| Nominal thickness | 1/4 inch, or 5mm |
| Density | 2 pounds per square foot |
| Approximate item weight | 123 pounds |

The material has a low initial odor that fades quickly. Also, its black color does not fade during exposure to the elements.
The nominal 5mm barrier combines flexibility with substantial roll weight. Its density requires careful handling during placement, especially across ceilings or broad vertical surfaces.
Installation and placement notes
The sheet can be cut with a razor. Also, installers can fasten it with staples, nails, or screws based on the substrate.
Sheathing tape can join seams and maintain continuity across adjoining sections. Next, the barrier can sit within wall cavities, flooring assemblies, or other layered construction systems.
The material supports placement in walls, ceilings, floors, and over doors. In addition, it can fit around windows, fences, pipes, and ductwork.
Its flexibility helps it conform to surfaces within wall cavities or flooring assemblies. However, the approximate 123-pound roll weight requires planning during lifting, positioning, and fastening.
Indoor and outdoor use broadens the placement options. The material also withstands environmental exposure without color fading.
Performance characteristics described
The barrier supports improved isolation of lower frequencies within construction assemblies. Also, its added mass contributes to increased resistance to airborne sound transmission.
Sound Transmission Class, or STC, relates to airborne sound transmission through an assembly. The material contributes to higher STC ratings when incorporated into construction projects.
The 2-pound-per-square-foot sheet belongs inside a structured sound control assembly. For example, it can sit behind drywall, under flooring underlayment, or within wall systems.
The material supports traffic-noise applications, home theater environments, and recording studio settings. In addition, vehicle, marine, and RV installations fall within its stated uses.
This barrier focuses on mass within an assembly. It does not function as a decorative finish surface. Instead, its placement typically keeps it concealed within the completed structure.
