Knauf Duct Liner E-M
Description
Knauf Duct Liner E•M is a flexible, mat-faced insulation made
from inorganic glass fibers bonded by a thermosetting resin with an
encapsulant edge coating. It is faced with a tightly bonded mat to
give the airstream surface a smooth, tough surface, resisting
damage during installation and operation. The encapsulant edge
coating eliminates airstream surface flaring.
Application
Specifically designed as an interior insulation material for
sheet metal ducts used in heating, ventilating, and air
conditioning. Provides an optimum combination of efficient sound
absorption, low thermal conductivity, and minimal airstream surface
friction.
Features
- Low thermal conductivity.
- Fire-resistant, non-corrosive, durable, and resilient.
- Tough, tightly bonded mat facing.
- Excellent sound absorption.
Benefits
- Energy conservation.
- Better temperature control.
- Lower operating costs.
- Greatly reduces noise from fans and mechanical equipment, as
well as noise from cross-talk and air movement.
- Withstands damage from normal handling and shop abuse.
- If necessary, can be cleaned in accordance with NAIMA's
“Cleaning Fibrous Glass Insulated Air Duct Systems Recommended
Practices.”

bacteria.
Application and Specification Guidelines
Storage
- Inside storage is recommended.
Fabrication and Application
- Fabricate in compliance with the latest edition of NAIMA's
Fibrous Glass Duct Liner Standard.
- Liner shall be folded and compressed in the corners of
rectangular duct sections or shall be cut and fit to assure lapped,
compressed joints. Longitudinal joints in duct liner should not
occur except at the corners of the duct. Longitudinal joints in
liner shall be coated with adhesive. All damaged areas of the air
stream surface shall be repaired with an adhesive that conforms to
ASTM C 916.
- Liner should be adhered to the duct with 90% minimum area
coverage of an adhesive taht conforms to ASTM C 916.
- Mechanical fasteners shall be located with respect to the
interior duct dimensions, regardless of air flow direction.
- Mechanical fasteners should not compress the insulation more
than 1/8" (3 mm), and shall be installed perpendicular
to the duct surface. All fasteners should comply with the
guidelines of NAIMA's Fibrous Glass Duct Liner Standard.
- Metal nosings shall be securely installed over transversely
oriented liner edges facing the air stream at fan discharge, at
access doors, and at any interval of lined duct preceeded by
unlined duct. In addition, where velocities exceed 4000 fpm (1219
mpm), metal nosing shall be used on upstream edges of liner at
every transverse joint.
Limitations
- Knauf Duct Liner E•M should not be used in systems operating at
velocities exceeding 6000 fpm (1829 mpm) or at temperatures above
250°F (121°C).
