Construction and Material Composition
The Tönnen Mass Loaded Vinyl 1.23 lb | 50 sqft | 4×12.5 ft | Easy to Carry roll. Professional MLV Soundproofing Barrier. Optimum thickness. Premium Noise Barrier. Sound Barrier (1.23 lb, 1/8 in, 50 sqft) consists of high-density, non-reinforced vinyl that weighs approximately 1.23 pounds per square foot. The sheet is 1/8 inch thick and measures 4 feet in width and 12.5 feet in length, yielding a total coverage area of 50 square feet. The material is flexible, odorless, and designed for direct application over joists, studs, or existing drywall surfaces.
Engineered without recycled content, this vinyl barrier aims to maintain consistent density and integrity across the entire roll. Its construction helps block sound transmission through partitions without compromising structural performance or requiring significant construction modifications.
Application Versatility
This product supports a wide range of applications across residential, industrial, and commercial settings. It can be installed behind drywall, beneath flooring underlayment, inside ceiling assemblies, or around ducts and pipes to reduce sound transmission from room to room or from mechanical sources. Because the Tönnen Mass Loaded Vinyl 1.23 lb | 50 sqft | 4×12.5 ft | Easy to Carry roll. Professional MLV Soundproofing Barrier. Optimum thickness. Premium Noise Barrier. Sound Barrier (1.23 lb, 1/8 in, 50 sqft) is highly pliable, it conforms well to irregular surfaces, making it suitable for both new builds and retrofits.
Installation can be performed using staples, nails, screws with washers, or acoustic adhesives. The product is not self-adhesive, allowing users to choose the appropriate installation method for their specific application. For enhanced acoustic performance, it can be layered with additional materials such as acoustic insulation or gypsum board.
Performance Characteristics
The high mass-to-thickness ratio of this 1.23 lb/sqft vinyl barrier is intended to reduce transmission of mid to high-frequency airborne noise. Although specific Sound Transmission Class (STC) ratings are not provided in the source materials, similar-density MLV products are typically known to achieve STC ratings in the 26–32 range when installed correctly. The lack of porous or fibrous components limits sound absorption, making this material more suitable for use as a barrier rather than a diffuser or absorber.
Its inert composition means the material does not support mold growth and offers stable performance over time. The flexibility and relatively low profile of the roll enable installation in tight cavity spaces without requiring significant build-out.
Durability and Handling
The roll is described as “easy to carry,” despite the full 50-square-foot coverage implying a total weight of over 60 pounds. This indicates a manageable form factor for most users. The Tönnen Mass Loaded Vinyl 1.23 lb | 50 sqft | 4×12.5 ft | Easy to Carry roll. Professional MLV Soundproofing Barrier. Optimum thickness. Premium Noise Barrier. Sound Barrier (1.23 lb, 1/8 in, 50 sqft) does not appear to require special handling beyond standard personal protective equipment typically used in construction environments.
There is no information regarding UV resistance or flame retardancy, so indoor use is presumed. The absence of odor and the product’s inert, non-reactive nature make it compatible with most building materials and finishes.
