Description
and Application:
Kinetics Model KNM-100AL/AL Cross Talk Barrier Material is designed to reduce
the sound transmission that occurs between two adjacent occupied spaces that
share an open cavity above the walls. When office or cubicle walls do not
extend to the ceiling deck, Model KMN-AL/AL can be hung as a cost effective
alternative to gypsum board and framing.
The material is constructed of mass loaded, limp vinyl with a layer of reinforced
aluminum foil face on both sides. The vinyl provides mass and flexibility,
while the aluminum adds increased mechanical strength, weatherability, and
improved fire retardancy. KNM-100 AL/AL is the only mass loaded vinyl barrier
that passes the vertical burn fire test, NFPA 701.
The non-lead composition of the material allows for safe handling and easy
installation.
Specification:
The barrier shall be constructed of a 0.10" (3 mm) thick barium sulphate,
mass-loaded, limp vinyl sheet bonded to a thin layer of reinforced aluminum
foil on both sides. The barrier shall have a nominal density of 1.0 lb./sq.
ft. (4.88 kg/sq. m.). The barrier shall exhibit minimum flammability ratings
of 0.0 seconds from flame out and afterglow and 0.2 inch (5 mm) for char length
when tested in accordance with Federal Test Std. No. 191-5903. The barrier
shall have a minimum thermal conductivity “K” value of 0.29 and a rated service
temperature range of -40°F to 220°F (-40°C to 104°C).
The barrier shall be Model KNM-100AL/AL as manufactured by Kinetics Noise
Control, Inc.
