Mass Loaded Vinyl 1.23 lb/ft2 - More Soundproofing - Professional MLV Soundproofing Barrier. Optimum thickness. Premium Noise Barrier | Sound Barrier | 4x20 ft (1.23 lb, 1/8 in, 80 sqft)

[The Pros Choose] - Provides 23% higher density compared to the 1lb/sf version. Our exclusive blend achieves an STC rating of 32 (Sound Transmission Class), linking greater absorption capacity with a higher STC value. This results in increased sound absorption, delivering proportionally higher STC returns per square foot. [Premium Soundproofing Material] - Our specially formulated vinyl chemical blend is designed to achieve optimal soundproofing (STC) across every square foot of wall space. Avoid the risk of closing up your drywall only to find it does not provide the desired outcome. [Rolls Weighing Less Than 100lb] - While other rolls frequently exceed the 100lb mark, requiring mechanical lifts, our rolls are engineered to weigh 97lb, eliminating the need for lifting equipment.

[Frame Compatibility and Broad Application] - Precisely tailored to match standard US framing width dimensions, this mass loaded vinyl design creates a strong sound barrier while maintaining a slim 1/8-inch thickness. It is also suitable for ceilings, floors, doors, HVAC systems, ducts, pipes, recording studios, home theaters, pool pumps, and pet houses
