Echo-Less™ Mass Loaded Vinyl (MLV)

High-Performance Acoustic Barrier & Soundproofing Membrane

Product Description

Echo-Less™ Mass Loaded Vinyl (MLV) is a premium acoustic barrier and soundproofing membrane engineered to reduce airborne noise transmission, minimise vibration, and improve acoustic performance across residential, commercial, industrial, automotive, and marine applications.

Manufactured from an ultra-high-density rubber compound reinforced with dense polymer metal powder, Echo-Less™ MLV delivers exceptional sound insulation while remaining flexible, durable, and easy to install. Its slim 3 mm profile allows it to be concealed behind plasterboard, within partition walls, beneath flooring, above suspended ceilings, and around ductwork, machinery, and doors without significantly increasing construction thickness.

By adding mass to lightweight building assemblies in accordance with the Mass Law principle of acoustics, Echo-Less™ MLV significantly improves sound insulation while reducing structure-borne vibration. It is an ideal solution for soundproofing walls, ceilings, floors, home theatres, recording studios, offices, apartments, hotels, HVAC systems, machinery enclosures, and commercial buildings where effective noise control is essential.

Its waterproof, moisture-resistant, corrosion-resistant, and Class B1 flame-retardant construction ensures outstanding long-term durability, making it suitable for demanding interior and semi-exposed environments.

Features:

Waterproof, Moisture Resistant & Corrosion Resistant

Echo-Less™ Mass Loaded Vinyl features a dense, low-permeability rubber and polymer composition with a durable non-woven fabric backing that effectively resists water penetration and moisture absorption.

Unlike many conventional soundproofing materials, Echo-Less™ MLV does not absorb moisture, helping to protect wall, ceiling, and floor assemblies from moisture-related deterioration while maintaining consistent acoustic performance throughout its service life.

Its corrosion-resistant properties make it particularly suitable for humid environments, HVAC installations, plant rooms, marine applications, automotive projects, and industrial facilities where long-term durability is essential.

Acoustic Performance

Sound Transmission Class (STC): Up to 60*

Echo-Less™ Mass Loaded Vinyl is an ultra-high-density acoustic barrier engineered to significantly reduce airborne sound transmission by increasing the mass of lightweight building systems.

Its dense rubber formulation effectively blocks airborne noise while simultaneously absorbing vibration, reducing resonance and minimising structure-borne sound transmission.

Whether installed within partition walls, beneath flooring, above ceilings, or around mechanical equipment, Echo-Less™ MLV delivers outstanding acoustic performance while maintaining a minimal installation thickness.

*Actual STC performance depends on the complete tested wall, floor, ceiling, or partition assembly and installation method.

Vibration Damping

The high-damping rubber compound absorbs and dissipates vibration before it can be transmitted through the building structure.

Its exceptional flexibility enables the material to conform around corners, ducting, pipework, machinery, and irregular surfaces while reducing vibration generated by HVAC systems, plumbing, industrial machinery, generators, vehicles, and home entertainment systems.

Fire Performance

Echo-Less™ Mass Loaded Vinyl is manufactured using a Class B1 flame-retardant formulation, providing enhanced fire safety for residential, commercial, and industrial applications.

The material resists ignition under normal operating conditions and is designed to limit flame spread. Under prolonged exposure to extreme heat, it may soften while producing relatively low levels of smoke compared with many conventional polymer-based materials.

Installation

Echo-Less™ Mass Loaded Vinyl is lightweight, flexible, and simple to install.

The material can be cut to size using a sharp utility knife and easily fitted around corners, columns, ductwork, pipework, and irregular building elements.

For optimum soundproofing performance:

1. Install directly onto timber or steel studs, masonry walls, ceilings, floors, or joists.

2. Secure using a suitable construction adhesive or mechanical fasteners.

3. Butt adjoining sheets tightly together.

4. Seal all joints, perimeter gaps, and service penetrations using acoustic sealant.

5. Apply acoustic barrier tape over seams where required.

6. Finish with plasterboard, plywood, or other suitable lining materials.

Proper sealing of all joints and penetrations is essential to achieve maximum acoustic performance.
