Sound Deadening Membrane 2.5mm | High-Density Acoustic Barrier for Wall, Floor & Ceiling Soundproofing

Our 2.5mm Sound Deadening Membrane is a flexible, high-mass acoustic sheet engineered to block airborne sound and reduce structural vibrations across a wide range of environments. Designed with mass-loaded vinyl (MLV) or polymeric sound barrier technology, it is ideal for multi-layer wall assemblies, floor underlays, ceilings, duct wraps, and industrial enclosures.

Despite its thin profile, this membrane delivers exceptional STC improvement, making it the perfect choice for space-conscious retrofits and professional-grade soundproofing.

Key Features:
