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 Acoustical Board Smooth represent typical average values
determined in accordance with accepted test methods. The data is
subject to normal manufacturing 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 materials under
actual fire conditions.
Check with your Knauf sales representative to assure
information is current.
