PrimaBlock - Loaded Vinyl Barrier
PrimaBlock™ Loaded vinyl barrier is a flexible, 1lb per square foot (4.9kg/m²) mass loaded vinyl that is used in construction to reduce sound transmission through walls, floors and ceilings. Typically sandwiched between layers of drywall or ideally suspended in the airspace between wall surfaces, PrimaBlock barrier helps reduce noise from plumbing, HVAC ducts and adjoining rooms by adding mass to the wall assembly. It is also commonly used in the design and construction of soundproof enclosures and bass traps, or can be wrapped around pipes, ductwork or loud machinery because it is so flexible.
