PrimaBlock™ Loaded vinyl barrier is a flexible, 1lb per square foot
(4.9m/kg2) 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.
PrimaBlock vinyl barrier is sold by the roll with an overall dimension
of 30’ x 4.5’ (9.1 x 1.4m). Total surface coverage is 135 sq. ft. per
roll. PrimaBlock Loaded vinyl barrier is finished in black and is
manufactured without the use of hazardous lead or heavy metals.
