High-Density Mass Loaded Vinyl Soundproofing Membrane | Professional Acoustic Material for Walls, Ceilings & Floors
The sound insulation performance of MLV is primarily based on two principles:
Mass Law
The high surface density of MLV increases the mass of the building assembly, making it more difficult for airborne sound waves to pass through the wall, ceiling, or floor structure.
Damping Effect
The flexible polymer structure helps reduce vibration and resonance within the building assembly, helping minimize sound transmission through structural components.
In practical applications, MLV is usually installed between layers of gypsum board, calcium silicate board, wood panels, or other structural boards. When combined with acoustic insulation and light gauge steel framing, it can significantly improve the overall sound insulation performance of the system.

Product Structure
Mass Loaded Vinyl is typically manufactured using a flexible high-density polymer composite containing:
High-Density Vinyl Resin
Provides the flexible and durable polymer matrix of the membrane.
Heavy Mineral Fillers
High-density mineral fillers, such as calcium carbonate or other mineral materials, increase the surface density of the membrane and improve its mass-based sound insulation performance.
Polymer Damping Additives
Damping additives help reduce vibration and resonance within the membrane and the surrounding building assembly.
Flexible Polymer Layer
The flexible structure allows the membrane to conform to different surfaces and makes it suitable for walls, ceilings, floors, pipes, ducts, and other irregular structures.
The resulting membrane combines high surface density, flexibility, durability, and ease of installation, making it suitable for a wide range of architectural and industrial acoustic applications.

Key Features
Excellent Airborne Sound Insulation
The high surface density of MLV helps reduce the transmission of airborne noise such as speech, television sound, equipment noise, and traffic noise, improving the overall acoustic performance of wall and ceiling assemblies.
Vibration Damping
The flexible polymer structure helps reduce vibration and resonance, helping control structure-borne noise when properly incorporated into an acoustic system.
Flexible and Easy to Install
MLV can be rolled, bent, cut, and fitted to different surfaces. It can be used on flat walls, irregular structures, pipes, ducts, and other areas where rigid soundproofing boards may be difficult to install.
Multiple Specifications Available
Different thicknesses, surface densities, widths, lengths, and fire-performance options can be supplied according to project requirements.
Low-Emission Options
Asbestos-free and low-VOC product configurations are available for interior building applications. Specific environmental performance should be confirmed according to the applicable product test report and market requirements.
Fire-Retardant Options
Both standard and fire-retardant grades can be supplied for applications where additional fire-performance requirements apply. Fire classification should be confirmed according to the specific product and applicable test standard.

Technical Specifications

Note: Sound insulation performance depends on the MLV specification, wall or ceiling construction, installation method, surrounding materials, and test conditions. The stated acoustic values should therefore be considered as reference values rather than guaranteed performance of the membrane alone.

Applications
MLV is widely used in architectural soundproofing and industrial noise-control systems.
Wall Soundproofing Systems
Suitable for:
Residential Party Walls
Hotel Partitions
Office Partitions
Hospital Rooms
School Classrooms
Commercial Buildings
MLV can be installed between layers of wall boards to increase the mass and damping of the wall assembly.
Ceiling Soundproofing Systems
MLV can be incorporated into suspended ceiling systems to help reduce sound transmission between floors, including airborne noise and certain impact-related noise.
Floor Soundproofing Systems
MLV can be used beneath wood flooring, laminate flooring, floating floors, and other floor assemblies to improve sound insulation and help reduce sound transmission through the floor structure.
Pipe & Duct Soundproofing
The flexible membrane can be wrapped around:
Drainage Pipes
HVAC Ducts
Ventilation Ducts
Industrial Pipes
Mechanical Systems
It can help reduce water-flow noise, equipment vibration, and mechanical noise when used as part of a properly designed acoustic treatment system.
Industrial Noise Control
MLV is suitable for noise-control applications in:
Equipment Rooms
Fan Rooms
Generator Rooms
Compressor Rooms
Transformer Rooms
Industrial Facilities
Mechanical Rooms

Recommended Installation Systems
Wall Soundproofing
Light Gauge Steel Framing → Acoustic Insulation → MLV → Gypsum Board / Calcium Silicate Board
For higher acoustic performance, multiple layers of boards and appropriate resilient connections can be incorporated into the wall design.
Ceiling Soundproofing
Structural Slab → MLV / Acoustic Layer → Hangers & Ceiling Framing → Gypsum Board Ceiling
The actual system should be designed according to the required acoustic performance and structural conditions.
Floor Soundproofing
Structural Floor → MLV → Resilient Underlay → Screed / Floor Finish → Flooring
The membrane can be incorporated into floating floor and impact-noise control systems where appropriate.
Pipe Soundproofing
Pipe → MLV → Acoustic Insulation → Protective Outer Layer
The MLV should be installed tightly around the pipe, with additional acoustic insulation and a suitable protective layer where required.

Frequently Asked Questions
Q1: What is the difference between MLV and acoustic insulation?
MLV and acoustic insulation perform different functions.
MLV primarily blocks sound transmission by adding mass and damping to a building assembly, while acoustic insulation such as mineral wool or fiberglass primarily absorbs sound energy within wall and ceiling cavities.
For better overall acoustic performance, MLV is often combined with acoustic insulation and multiple layers of wall boards.
Q2: Where can MLV be installed?
MLV can be used in a variety of applications, including light gauge steel partition walls, gypsum board walls, suspended ceilings, floors, pipes, ducts, equipment enclosures, and industrial noise-control systems.
Q3: Does a thicker MLV always provide better soundproofing?
Generally, increasing surface density can improve the mass-based sound insulation performance of an assembly. However, the final result also depends on wall construction, framing, insulation, board layers, installation quality, and acoustic detailing.
A properly designed acoustic system is more important than simply increasing membrane thickness.
Q4: Is MLV fire resistant?
We can provide standard and fire-retardant MLV options. Specific fire performance depends on the product formulation and applicable test standard. For projects with fire-rating requirements, we recommend confirming the required classification and test documentation before selection.
Q5: Is MLV environmentally friendly and suitable for homes or schools?
Asbestos-free and low-VOC product options are available for interior applications. Environmental and emission performance should be verified using the relevant product test reports and standards required in the target market.
Q6: Can MLV be customized?
Yes. We support customization of thickness, surface density, width, roll length, surface treatment, fire-performance requirements, packaging, and branding.
Q7: How should MLV be installed for better soundproofing performance?
For building applications, MLV is generally most effective when incorporated into a complete multi-layer acoustic system. A typical wall assembly may include light gauge steel framing, acoustic insulation, MLV, and one or more layers of gypsum board or calcium silicate board.
Proper sealing, fastening, joints, and acoustic detailing are also important to minimize sound leakage.
Q8: What complementary products can you supply?
In addition to MLV, we can supply damping soundproof boards, light gauge steel framing, acoustic insulation, fiberglass acoustic panels, calcium silicate boards, mineral wool acoustic panels, polyester acoustic materials, and related building accessories.
