Perforated Metal Acoustic Panels
KINETICS® KNP

Perforated Metal Acoustic Panels

A highly durable perforated metal acoustic panel. Ideal solution to airborne noise problems in demanding environments. Available with flat or V-groove face.

Description

KNP sound absorbing panels are functional and aesthetically pleasing perforated panels which are used to control reverberant noise problems. Although primarily intended as an absorber, KNP perforated metal panels will act as a barrier when a solid back is added. KNP sound absorping panels are useful as additions to existing metal or concrete barriers to reduce reverberation time and to lower reflected sound.

Application

KNP perforated metal panels deliver ample sound absorption over a wide frequency range. KNP acoustical properties, appearance, and rugged durability make it the choice for controlling reverberant, noisy spaces where panels must resist damage from impacts, abrasion, or moisture.

  • Waste Water Treatment Facilities
  • Pump Rooms
  • Mechanical Equipment Yards
  • Gymnasiums
  • Natatoriums
  • Multi-Purpose Rooms
  • Recreational Facilities

KNP perforated metal panels can be attached to walls, ceilings, or other surfaces and can be located in a manner to achieve an aesthetically pleasing pattern. Kinetics sound absorbing panels are available with optional rear backing to increase transmission loss and be used as a barrier. Available faced with perforated material on both sides and used as hanging absorptive baffles.
