ASLONG Professional Mass Loaded Vinyl Barrier Roll — High-Density Sound Insulation

ASLONG’s Professional Mass Loaded Vinyl (MLV) Barrier Roll is a high-density, flexible soundproofing membrane designed to block airborne noise by adding limp mass to partitions. Made from formulations optimized for acoustical performance, the mass loaded vinyl barrier roll uses its high surface mass and damping properties to reflect and absorb sound energy, effectively lowering transmitted noise when applied to walls, ceilings, floors, vehicles, or industrial enclosures. ASLONG (Welllink Guangdong New Material Co., Ltd.), founded in 2000, develops and manufactures these materials in a modern 10,000+ m² facility, supplying engineered solutions for construction, automotive, residential, and entertainment applications.

Typical MLV specifications vary by model. Common options: mass loading from 0.5 to 2.0 lb/ft² (≈2.4–9.8 kg/m²), thickness generally 1.5–5 mm, roll widths 0.6–1.5 m and custom lengths available. In real installations, MLV can improve airborne sound transmission (STC) by roughly +7 to +15 dB depending on construction details, attachment method, and the rest of the build-up. Operating temperature range is typically -20°C to +80°C. Exact performance, fire classification, and mechanical properties depend on formulation — please request the product datasheet and test reports from ASLONG for precise values tailored to your chosen grade.

Follow these professional installation steps: 1) Prepare surfaces — clean and dry. 2) Measure and cut MLV with a utility knife or heavy shears. 3) Overlap seams 50–100 mm (2–4 inches) and seal with an acoustic sealant or foil tape to maintain an airtight barrier. 4) Mechanically fasten (screws with washers) or use a compatible contact/solvent-based adhesive depending on substrate; in many wall applications a combination of adhesive plus mechanical fasteners is recommended. 5) Combine MLV with decoupling (resilient channels), absorption (mineral wool or acoustic foam), and a finished layer (drywall, plywood) to maximize STC gains. For floors, use as an underlayment with a protective layer; for vehicles, stick and mechanically secure to sheet metal, avoiding heat sources and moving parts. Always follow local building codes and request ASLONG installation guidance for your assembly.

ASLONG’s MLV formulations are manufactured to meet industry safety and environmental expectations. Many grades are low-VOC and free from heavy metals, but exact composition and certifications vary by product. Fire performance depends on the chosen formulation — flame-retardant grades are available. ASLONG provides material safety data sheets (MSDS/SDS), product datasheets, and can supply test reports such as ASTM/EN fire and acoustic test results upon request. For project compliance, ask ASLONG for the specific grade’s certificates (e.g., ASTM E84, EN tests, or UL listings) and recycling/disposal recommendations tailored to local regulations.

Yes. ASLONG offers custom widths, roll lengths, surface treatments, and multiple weight/thickness options to meet project specifications. Samples are typically available for evaluation; lead times depend on order size and customization but ASLONG exports to Europe, North America, Asia, and Africa. The company is a high-tech enterprise with a 10,000+ m² production base and is recruiting agents worldwide.
