QUIET BARRIER® LD Composite is a composite of half pound mass loaded vinyl and half inch polyether foam designed to block / absorb sound in noise polluted environments. The vinyl is a flexible, high density material with a smooth surface created to reduce noise transmission and is resistant to most acids, mild alkalis and oils / grease. The foam acts as a decoupler and an absorber. As a decoupler, it limits vibration of the mass loaded vinyl. As an absorber, it captures noise radiating from structural or airborne sources. QUIET BARRIER® LD Composite is available with a pressure sensitive adhesive (PSA) for an easy ‘peel and stick’ application. STC 20 / NRC 0.25   Click here to view WALL ASSEMBLIES that allow you to achieve higher STC ratings.

QUIET BARRIER® LD Composite is an effective, economical option for sound abatement. It may be applied directly to drywall or attached to studs / joists prior to the administration of drywall. Block sound transmission through doors by applying QUIET BARRIER® LD Composite to one side of the door.   Compare with our QUIET BARRIER® HD Composite and our QUIET BARRIER® MD Composite
