Description:
Kinetics KBC Barrier Composites are thin, rugged, high-performing, flexible acoustical composites designed to solve difficult noise control applications where sound absorption must be increased and sound transmission must be reduced. Kinetics Model KBC Barrier Composites are available with 1/2,1 or 2 psf (2.5, 4.9 or 9.8 kg/m2) loaded vinyl barriers with a quilted aluminum cloth faced fiberglass absorber on one or both sides of the barrier.
Kinetics Models KBC-50RBQ and 100RBQ are used when a noise source is located on one side of the acoustical material. Sound originating from the source is initially absorbed by the fiberglass and then blocked by the sound barrier. The reflected sound waves are further dissipated by the fiberglass absorber.
Model KBC-50BQQ, 100BQQ, and 200BQQ perform in the same manner except that they are designed to absorb sound on both sides of the composite, with one side acting as a decoupling layer.
Model KBC Barrier Composites can be installed free hanging or attached directly to a noise-radiating surface. Models KBC-50BQQ, 100BQQ, and 200BQQ are ideal as an internal lining on any rigid structure that requires significant transmission loss improvement. In this manner, the limp mass vinyl barrier is decoupled from the structure by the fiberglass absorber which allows the barrier to vibrate freely thus increasing sound transmission loss performance.
Application:
KBC Barrier Composites are ideal for many diverse industrial & OEM applications where both reverberation control and sound transmission loss are required. Industrial applications include enclosures, machinery cover linings, and additions to existing walls or barriers. Architectural applications include crosstalk barriers, room dividers, ceiling barriers, and pipe and duct wrap.
KBC-50BQQ, 100BQQ, and 200BQQ material can be used where Class 1 fire and smoke performance is required.
