| Kinetics Duct Lagging Barrier -
Type KNM-100ALQ Kinetics Model
KNM-100ALQ noise barrier is a composite material designed to
reduce the sound transmission of ductwork, piping and equipment housings by combining a
fire rated limp mass with a decoupling quilted fiber glass lining. (KNM-100AL is available
without the quilted fiber glass lining).
The non-lead composition of the barrier material allows for safe
handling and easy installation. When applied with Kinetics quilted absorber, Kinetics
fire-resistant barrier material is simply cut to length, wrapped around the pipe or duct
and fastened with adhesive, tape, mechanical fasteners or bands.
The material is constructed of a rugged reinforced aluminized-faced
loaded limp mass vinyl bonded to a scrim-faced quilted fiber glass absorber/decoupler. The
vinyl provides mass and flexibility, while the aluminum adds increased mechanical
strength, weatherability, attractive appearance and improved fire retardancy. To decouple
the mass layer from the noise or vibration source, Kinetics Model KFA quilted absorber is
used.
Meets Class 1 fire rating
requirements
STC 28*
1" or 2" fiber glass
decoupler included
Specifications: The barrier shall be constructed of a 0.10" thick barium sulfate loaded
limp vinyl sheet bonded to a thin layer of reinforced aluminized facing. The barrier shall
have a nominal density of 1.0 lb./sq. ft. and shall have a minimum STC rating of 28. The
barrier shall exhibit minimum flammability ratings of 0.0 seconds for flame out and
afterglow and 0.2 inches for char length when tested in accordance with Federal Test Std.
No. 1915903. When tested for Surface Burning Characteristics per ASTM E84, the barrier
will have a Flame Spread Index of no more than 10 and a Smoke Development Index of no more
than 40. The decoupling layer shall be a combination of [1", 2"] fiber glass
batting, non woven porous scrimcoated glass cloth, quilted together in a matrix of 4"
diamond stitch pattern which encapsulates the glass. (Note: KNM-100AL is available without
the quilted fiber glass lining).
