Product Description

Product Description

Damping soundproof felt, also known as Mass Loaded Vinyl (MLV), is a high-density limp acoustic barrier for low-frequency noise and impact vibration, outperforming common absorbers like rock wool and glass wool.

Working on the damping principle, it turns structural vibration into heat to block solid-borne sound, ideal for reducing footfall noise, pipe knocking, machine vibration, elevator resonance and KTV bass leakage.

Soft, thin and flexible, it is easy to cut and bend for walls, floating floors, ceilings, curved pipes and irregular structures, with minimal thickness added for space-limited renovations.

Waterproof, moisture-proof and anti-aging, it stays stable in damp areas such as basements and machine rooms. Custom flame retardant grades are available to meet local fire codes.

Widely used for residences, hotels, KTVs, recording studios, cinemas, machine rooms, elevator shafts and pipe noise control. Standard thickness: 1.2/2/3mm. Custom width, length and density are offered for varied acoustic needs.

For better performance, combine it with rock wool or glass wool to form a full acoustic system. OEM & ODM are available for contractors, distributors and construction firms.

Mass Loaded Vinyl

Core Advantages of Damping Soundproof Felt (MLV)

Excellent Low-Frequency & Impact Noise Control

Made of high-density limp mass material, it works on the damping principle to convert vibration energy into heat. It blocks solid-borne noise that ordinary absorbers like glass wool and rock wool cannot handle well, effectively reducing footfall sound, pipe knocking, elevator resonance and KTV bass leakage.

Flexible & Space-Saving Installation

Soft, thin and bendable, it can be freely cut to fit walls, floating floors, ceilings, curved pipes and irregular structures. It adds little thickness, ideal for renovation projects with limited ceiling height.

Waterproof, Moisture-Proof & Anti-Aging

It stays stable in damp environments such as basements and machine rooms, without becoming brittle, soft or moldy. Custom flame retardant grades are available to satisfy local building fire codes.

Wide Application & Customization

Suitable for residences, hotels, KTVs, recording studios, cinemas, machine rooms and elevator shaft noise control. Standard thickness:1.2/2/3mm. Custom width, length and density are available for different acoustic design requirements.

Perfect Match With Sound-Absorbing Materials

Combined with glass wool or rock wool, it creates a complete acoustic system of damping barrier + sound absorption for superior noise reduction. OEM & ODM are supported.

FAQ

Q1: What is MLV damping soundproof felt mainly used for?

A: It is designed to block low-frequency noise and impact vibration, widely used for walls, floors, ceilings, pipes, KTVs, recording studios and elevator shafts.

Q2: Can the damping soundproof felt work alone for sound insulation?

A: It can reduce vibration noise alone. For better sound insulation effect, it is recommended to use it together with glass wool or rock wool.

Q3: How to install the damping soundproof felt correctly?

A: It can be cut easily on site, fixed by adhesive or screws. Overlap the seams properly to avoid sound leakage.

Q4: Can you customize flame retardant grade, size and density?

A: Sure. We support customized thickness, width, length, density and flame retardant grades to meet different project standards.

Q5: Is it waterproof and suitable for damp environments?

A: It is waterproof and anti-aging, stable for use in basements, machine rooms and other humid areas
