Mass Loaded Vinyl Soundproofing – Luxury Liner Pro by Second Skin Audio | 1lb MLV Sound Barrier with Closed Cell Foam for Floor, Ceiling & Automotive Noise Control 3/8" Sheet - 1 Sheet

Mass-loaded vinyl soundproofing works by adding weight between you and the noise. Luxury Liner Pro combines a 1lb mass-loaded vinyl barrier with bonded closed cell foam, creating a single 3/8 inch composite designed to block airborne sound while limiting direct contact with the structure. The dense MLV layer reduces sound transmission from road noise, engine vibration, exhaust, neighbors, and mechanical equipment. With an STC rating of 28, it targets mid to high frequency noise that travels through floors, ceilings, doors, and wall assemblies. The attached foam acts as a decoupling layer, helping prevent the barrier from sitting directly against the surface, which improves real-world performance in floor soundproofing and ceiling soundproofing for apartment retrofits. This is not a vibration damper. For best results, install over a constraint layer damper on sheet metal or pair with proper isolation in building assemblies. Coverage matters. Gaps reduce effectiveness, so plan for 100% surface coverage when building a sound barrier for basement ceiling systems, automotive cabins, or equipment enclosures. Each 24" x 54" sheet covers 9 sq ft and weighs 1.25 lb per sq ft, balancing density and handling. The material cuts with a utility knife and conforms to contours without tearing. Install foam side down, vinyl side facing the noise source interior. Rated to 180°F, it also provides thermal resistance in firewall and transmission tunnel applications. Luxury Liner Pro is built for installers who want mass-loaded vinyl panels and decoupling in one controlled layer, without stacking separate products or guessing at assembly order.

• True Noise Barrier Performance: 1lb mass-loaded vinyl soundproofing fused to closed cell foam; blocks airborne noise from road, engine, neighbors, and equipment; STC 28 barrier layer reduces mid to high frequency transmission in floors, ceilings, and cabins
• Built-In Decoupling Layer: MLV soundproofing bonded to resilient foam eliminates the need for separate underlayment; foam side down prevents direct contact with structure; improves floor soundproofing and ceiling soundproofing for apartment retrofits
• Designed for Full Coverage Systems: Mass-loaded vinyl sound barrier must cover 100% of the surface to work; installs over a constraint layer damper for best results; ideal for cabin side firewall, basement ceiling, trunk, cargo area, and wall assemblies
• Flexible 3/8 Inch Composite Sheet: 24" x 54" mlv panel at 1.25 lb per sq ft balances density and handling; cuts with a utility knife; conforms to contours without tearing; suitable for automotive builds, renovation projects, and outdoor sound barrier enclosures
• Heat and Noise Control in One Layer: Closed-cell foam adds thermal resistance while the mass-loaded vinyl blocks sound; rated to 180°F; helps reduce engine and transmission tunnel heat transfer without sacrificing acoustic performance
