Target Applications

01/

Drywall & Stud Wall Assembly: MLV installed directly over wood or steel studs prior to drywall attachment reduces airborne sound transmission across low and mid frequencies.

02/

HVAC & Industrial Piping: Foil-faced MLV applied over ductwork and industrial piping suppresses fluid velocity noise and breakout acoustic vibration.

03/

Equipment & Compressor Enclosures: Multi-layer acoustic noise barriers cut direct machine radiated noise when suspended around generators, chillers, or stamping presses.

04/

Perimeter Construction Sites: UV-resistant exterior acoustic barriers hanging on chain-link fences or scaffolding suppress heavy machinery noise during urbanization work.

Customization & Installation Engineering

OEM Fabrication Options
Density & Weight Adjustment: Precision formulation adjustments from 1.5 kg/m2 to 10.0 kg/m2.

Slitting & Die-Cutting: Roll widths cut from 300 mm up to 1500 mm. Precision die-cut sheets for machine casing linings.

Reinforcement Layering: Scrim reinforcement insertion for mechanical fastening strength on vertical suspensions.

Hardware Accessories: Stainless steel or brass grommets, heavy-duty Velcro strips, and isolation tape integrated directly into panel borders.

Field Installation Methods
Mechanical Fastening: Fasten MLV to studs using large-head roofing nails or pneumatically driven staples with neoprene washers to prevent tearing under self-weight.

Sealing & Overlapping: Overlap roll joints by at least 50 mm (2 inches). Seal all seam lines completely using acoustic caulk and high-tack pressure-sensitive tape to eliminate sound flanking paths.

Pipe & Duct Wrapping: Secure foil-faced MLV wrapping with mechanical band straps or pressure-sensitive aluminum foil tape at every joint seam.

Quality Control & Compliance

Our manufacturing line uses automated continuous thickness control and gravimetric inline dosing systems to maintain consistent density and acoustic performance across every batch.

FAQ

Q: What is the primary difference between sound insulation materials (MLV) and sound absorption panels?

A: Sound insulation materials like MLV are dense, heavy barriers engineered to block sound transmission from passing through a wall or ceiling assembly. Sound absorption materials, such as PET felt or glass wool, are porous structures designed to reduce reverberation and echo within a single room space.

Q: How does Mass Loaded Vinyl achieve high STC ratings despite its thin profile?

A: MLV relies on high material density (formulated with heavy minerals like barium sulfate) combined with viscoelastic flexibility. The unbacked limp mass absorbs acoustic wave energy through internal friction without vibrating sympathetically like rigid sheet metal or drywall.

Q: Can your MLV materials pass local fire safety codes in commercial building contracts?

A: Yes. Our MLV products are formulated with flame-retardant additives to meet ASTM E84 Class A flame spread index (< 25) and smoke development index (< 50), as well as European standard EN 13501-1 Class B-s1, d0. Test certificates from accredited third-party laboratories are available upon request.

Q: What roll dimensions and custom cut sizes are available for wholesale orders?

A: Standard MLV roll sizes are 1.0 m x 10 m, 1.2 m x 5 m, or 1.2 m x 10 m. We provide custom slitting down to 300 mm widths or die-cut customized sheet sizes according to your project's technical drawings.

Q: How do you handle seam sealing to avoid acoustic flanking paths?

A: For drywall installations, overlap MLV seams by 50 mm (2 inches) and seal all seams with acoustic caulk. On butt-joint installations or foil-backed duct lagging, apply high-tack acoustic tape over all joint seams to ensure airtight integrity.

Q: What is your typical production lead time for full container load (FCL) orders?

A: Standard lead time for a 20ft or 40ft container load (18,000 kg - 26,000 kg) is 12 to 15 business days from order confirmation. Custom formulations, die-cut shapes, or specific grommet hardware additions require 15 to 20 business days.
