Mass Loaded Vinyl Barrier 2.5mm | Flexible, High-Mass Acoustic Sheet for Premium Soundproofing

Our 2.5mm Mass Loaded Vinyl (MLV) Barrier is a high-density, flexible soundproofing membrane engineered to block airborne sound and structural vibrations effectively. With a density of approximately 55.5 kg/m, it delivers STC improvements of 812 dB, making it ideal for high-performance soundproofing in walls, ceilings, floors, and enclosures.

Used widely in residential, commercial, automotive, and OEM acoustic solutions, this membrane can be layered, glued, or suspended as part of any sound isolation system.

Key Features:

• Thickness: 2.5mm optimal for high-performance + flexible use

• Density: 55.5 kg/m blocks low to mid frequency noise

• Material: Lead-free, non-toxic polymer + mineral composite (MLV)

• Improves STC by 812 dB in layered construction

• Excellent for retrofitting without bulky construction

• Flexible and easy to cut, bend, wrap, or sandwich between panels

• Resistant to moisture, fire (Class B / ASTM E84), and fungal growth
