Kinetics Noise Control Launches PR-KNM Mass Loaded Vinyl Barrier

The Only Acoustical Plenum & Class-A Rated MLV on the Market

DUBLIN, March 26, 2026 /PRNewswire/ -- Kinetics Noise Control Inc. (Kinetics), a Catalyst Acoustics Group brand, is proud to announce the launch of PR-KNM, a plenum-rated mass-loaded vinyl (MLV) barrier engineered to deliver high-performance sound blocking while meeting the most stringent fire and smoke requirements for plenum spaces.

PR-KNM meets the enhanced standard of plenum rating, allowing it to be specified in return air plenums and ceiling cavities where conventional Class A MLV barriers cannot be used. While some MLV products may meet ASTM E84 Class A criteria, plenum applications require a significantly lower smoke developed index of 50 or less. PR-KNM provides the sound-blocking performance of traditional MLV while satisfying these stricter smoke requirements.

Designed for modern building systems, PR-KNM is ideal for duct wrap, return air plenums, ceiling cross-talk control, and isolation between equipment rooms and occupied spaces. Adding mass and blocking airborne transmission reduces HVAC noise and vibration while maintaining full code compliance.

"PR-KNM eliminates the tradeoff between acoustic performance and plenum compliance," said Ben Vause, Director of Sales – Building Acoustics, Kinetics Noise Control. "This product gives engineers and contractors a defensible solution that meets enhanced smoke requirements while delivering the sound control performance they expect from Kinetics."

PR-KNM is available in bare, foil-faced, and foil-faced quilted configurations to support a range of application needs.
