Kinetics KFA quilted fiberglass absorbers can be used in many diverse industrial or OEM applications including absorptive linings
for machinery housings, building walls, curtain or fixed enclosures, compartments, hoods, operator cabs, piping and duct work or
wherever reduction of reverberant noise is required.
KFA fundamental component is a low binder, fine fiber, acoustically absorptive, fiberglass batting. Two different reinforced, nonporous,
fiberglass cloth facing materials are available and are quilted directly to the fiberglass batting using high strength thread and locking
stitches. The quilting forms a matrix of 4" (102 mm) diamond stitch patterns which encapsulate the glass fibers. When the facing material
on these stable encasements is subjected to airborne sound waves, the individual membrane faces respond diaphragmatically, like a drum head,
and transmit sound energy through the nonporous facing into the fiberglass batting core material, where it is dissipated as thermal energy.
Available as single or double layer, nominal thickness 1" (25 mm) or 2" (51 mm). Double layer thickness increases low frequency absorption and
provides significant transmission loss characteristics.
Depending on application requirements, the quilted absorbers can be faced on one or both sides. Available facings include the standard
aluminum-vinyl coated fiberglass cloth (A), impervious high-temperature silicone-coated fiberglass cloth (S) which is quilted using a Nomex
stitching thread, or nonmaintenance, nonwoven, porous, scrim fabric (N). The three facing materials can be used individually or in combination
on the same absorber so that special properties or economies can be achieved.
