Mass loaded vinyl (MLV) & acoustic membranes

Mass loaded vinyl (MLV) is a flexible, high-density soundproofing material designed to add acoustic mass to walls, floors, ceilings and other suitable constructions.

It is commonly supplied in thin sheets or rolls and can help reduce airborne sound transmission without requiring the thickness of some conventional soundproofing materials.

MLV is typically used alongside other acoustic materials as part of a complete soundproofing system.

The main difference is the amount of acoustic mass each product provides.

Barrier Mat 5kg has a nominal mass of 5kg/m² and is approximately 2mm thick.

Barrier Mat 10kg provides 10kg/m² at approximately 4mm thick.

The heavier membrane adds more mass, which can be beneficial for airborne sound insulation. However, the best option depends on the construction, available space and overall acoustic system.

Self-adhesive MLV offers a different installation method rather than automatically providing better sound insulation.

Products such as Self Adhesive MLV 50 and Self Adhesive MLV 100 include an adhesive backing designed for bonding to compatible surfaces.

Standard barrier mats require a suitable fixing or bonding method, depending on the application.

The most appropriate option depends on the surface, construction and manufacturer's installation requirements.

Yes. Mass loaded vinyl can help reduce airborne noise such as conversations, television and music when incorporated into a suitable wall or ceiling soundproofing system.

Its high-density construction adds acoustic mass, helping limit sound transmission through the assembly.

For more demanding noise problems, MLV may need to be combined with acoustic plasterboard, insulation and resilient isolation components.

Yes. Mass loaded vinyl can be incorporated into compatible floor constructions to add acoustic mass and help improve airborne sound insulation.

However, impact noise from footsteps, dropped objects and furniture movement generally requires additional resilient layers or isolation components.

The correct approach depends on the existing floor construction, floor covering and type of noise being transmitted.

Some MLV installations may be suitable for experienced DIY users, particularly where a self-adhesive membrane is appropriate for the intended surface.

Correct positioning, fixing, joint treatment and perimeter detailing are important to achieving the intended acoustic performance.

Always follow the manufacturer's installation guidance. For complex wall, floor or ceiling soundproofing systems, professional installation may be advisable.
