Description
Knauf Type KN Series Insulation is
an amber blanket of glass fibers bonded with a thermosetting
resin.
Packaging
Knauf Type KN Series Insulation is
placed in a poly bag, vacuum packaged, and slipped into a poly
sleeve. The end of the bag is closed with a plastic tie.

Applications
KN Series products are used as
thermal and/or acoustical insulation in the appliance, equipment,
industrial, commercial, and marine markets up to 650°F
(271°C).
Fiber Glass and
Mold
Fiber glass insulation will not
sustain mold growth. However, mold can grow on almost any material
when it becomes wet and contaminated with organic materials.
Carefully inspect any insulation that has been exposed to water. If
it shows any sign of mold it must be discarded. If the material is
wet but shows no evidence of mold, it should be dried rapidly and
thoroughly. If it shows signs of facing degradation from wetting,
it should be replaced. Air handling insulation used in the air
stream must be discarded if exposed to water.
Notes
The chemical and physical properties
of Knauf Type KN Series represent typical average values determined
in accordance with accepted test methods. The data is subject to
normal variations. The data is supplied as a technical service and
is subject to change without notice. References to numerical flame
spread ratings are not intended to reflect hazards presented by
these, or any other material under actual fire conditions.
