dB-Bloc™ is a high-performance mass loaded vinyl (MLV) sound barrier designed to block sound transmission through walls, ceilings, and floors. At just 1/8" thick (1 PSF) or 1/4" thick (2 PSF), this flexible, dense material adds substantial sound-blocking mass without taking up valuable space.

Ideal for soundproofing both new construction and retrofit applications, dB-Bloc is commonly installed behind drywall, beneath flooring, or inside ceiling systems to reduce noise transfer between rooms or from exterior sources.
