ASLONG Flexible Mass Loaded Vinyl Sound Barrier — High-Mass Acoustic Shield for Home, Auto & Industry

ASLONG Flexible Mass Loaded Vinyl (MLV) Sound Barrier is a high-mass, flexible acoustic shield designed to block airborne noise in retrofit and new-build projects. Using the Mass Loaded Vinyl principle—adding mass in a thin, pliable sheet—we increase sound transmission loss according to the mass law, so less airborne sound passes through walls, floors, ceilings or vehicle panels. As a manufacturer since 2000 with an R&D-driven production base, we offer multiple weights and thicknesses of MLV optimized for home, automotive and industrial applications. For precise performance numbers and product datasheets, please contact us and we will provide test reports and sample recommendations.

Yes. Our Mass Loaded Vinyl is designed for broad applications: residential (partition walls, ceilings, underfloor, HVAC ducts), automotive (doors, floors, trunks, engine bays), and industrial (machinery enclosures, plant walls, acoustic booths). Because MLV is thin and flexible, it is ideal for retrofit situations where adding mass without increasing thickness is critical. ASLONG products—including MLV, butyl damping mats and NBR foam—are already used across construction, automotive and entertainment facilities worldwide. Tell us your application and we’ll recommend the right product grade and installation method.

ASLONG Mass Loaded Vinyl is compatible with drywall, studs, plywood, metal panels and most vehicle interiors. Typical installation methods include adhesive bonding, mechanical fastening (screws or rivets with washers), and sealing overlaps with tape or sealant. For best results, overlap seams by 2–4 cm and use our butyl waterproof tape or butyl rubber damping mat to eliminate flanking paths. For automotive installs, we recommend removing interior panels where practical and fastening MLV to the inner skins or door cores. We provide installation guides, recommended accessory products and technical support to ensure correct adhesion, fire-safety considerations and long-term performance.

Acoustic gains depend on the MLV weight, thickness and the existing assembly. In common retrofit scenarios, adding quality Mass Loaded Vinyl can raise Sound Transmission Class (STC) by several points and reduce perceived airborne noise by a noticeable margin. Typical MLV product options range across industry-standard mass values to suit different needs—lighter options for space-limited projects and higher-mass grades for maximum sound blocking. Because real-world results vary with construction details, we provide lab test data and case-study performance for specific assemblies upon request. Contact us for detailed specifications, STC/Lab reports and a tailored recommendation.

We manufacture Mass Loaded Vinyl in our modern, >10,000 m² production base using high-quality materials and process controls to ensure long-term durability, dimensional stability and resistance to moisture and aging. ASLONG is a high-tech enterprise founded in 2000; our acoustic and sound-insulation products are exported globally. We can provide material safety data, testing and certification information on request and offer technical guidance for safe handling and end-of-life considerations.
