Knauf Equipment Liner M
Description
Knauf Equipment Liner M is a black
flexible fiber glass blanket with a facing adhered to the air
stream side. The product provides thermal and acoustical insulation
while providing a smooth, tough air stream surface which resists
damage during installation and operation.
Application
It is used to provide noise
reduction and thermal insulation for equipment (air conditioning,
heating) where air erosion resistance is required. The
product is designed for systems operating at temperatures up to
250°F (121°C) and velocities up to 6000 fpm (1829 mpm).
Technical Data
Fire Resistance
- Meets NFPA 90A and NFPA 90B Standards
for fire safety.
Temperature Range (ASTM C
411)
Air Velocity (ASTM C
1071)
- Maximum 6000 fpm (1829 mpm).
Water Vapor Sorption (ASTM C
1104)
Surface Burning
Characteristics (UL/ULC Listed)
- When tested in accordance with ASTM E
84, UL 723, CAN 4-S102, and NFPA-255, Knauf Equipment Liner M does
not exceed 25 Flame Spread, 50 Smoke Developed
Microbial Growth (ASTM C
1338, G 21, G 22)
- The airstream surface mat facing is
treated with an EPA-registered anti-microbial agent to aid in the
prevention of fungal and bacterial growth.
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 Equipment Liner M 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.
