AbsolutAire Linacoustic RC User Manual
Air Handling Systems
Description
inacoustic RC is a flexible duct liner insulation made from
L
strong, glass fibers bonded with a thermosetting resin. The
airstream surface is protected with JM’s exclusive Reinforced
oating System, which combines our state-of-the-art
C
Permacote
®
acrylic coating with a flexible glass cloth
reinforcement.
Factory-Applied Edge Coating
Edge coating is factory applied to the edges of the liner core,
assuring coverage of the leading edges per NAIMA/SMACNA
requirements. Shop fabrication cuts may be coated with the
SuperSeal
®
Duct Butter and Edge Treatment products (refer to
publication AHS-202).
Uses
Linacoustic RC is specifically designed for lining sheet metal
ducts in air conditioning, heating and ventilating systems,
providing superior acoustical and thermal performance.
Advantages
Improves Indoor Building Environment.
Linacoustic RC improves
indoor environmental quality by helping to control both
temperature and sound.
Resistant to Dust and Dirt. The tough, acrylic polymer Permacote
coating helps guard against the incursion of dust or dirt into the
substrate, minimizing the potential for biological growth.
Will Not Support Microbial Growth. Permacote coating is
formulated with an immobilized, EPA-registered, protective
agent to protect the coating from potential growth of fungus
and bacteria.
Linacoustic RC duct liner meets all requirements of ASTM C 1071
for fungi and bacterial resistance. Tests were conducted in
accordance with ASTM C 1338 and ASTM G 21 (fungi testing)
and ASTM G 22 (bacteria resistance testing). Detailed
information is available in Johns Manville fact sheet HSE-103FS.
Note: As with any type of surface, microbial growth may occur in
accumulated duct system dirt, given certain conditions. This risk
is minimized with proper design, filtration, maintenance and
operation of the HVAC system.
GREENGUARD®. This certification is proof that the product meets
the Environmental Institute’s indoor air quality standards for
VOCs.
Cleanability. If HVAC system cleaning is required,
the Reinforced Coating airstream surface may be
cleaned with industry-recognized dry methods. See the North
American Insulation Manufacturers Association (NAIMA)
“Cleaning Fibrous Glass Insulated Air Duct Systems.”
Minimizes Pre-Installation Damage. Linacoustic RC’s
Reinforced Coating System is highly resistant to damage that
can occur during in-shop handling, fabrication, jobsite shipping,
and installation.
Linacoustic RC
™
Fiber Glass Duct Liner With Reinforced Coating System
Highly Resistant to Water. The Reinforced Coating surface
provides superior resistance to penetration of incidental water
into the fiber glass wool core.
Easy to Fabricate. Linacoustic RC is light in weight and easy to
handle. Clean, even edges can be accurately cut with regular
shop tools.

Installation
Linacoustic RC installation must be performed in accordance
with the requirements of the NAIMA Fibrous Glass Duct Liner
Standard, or SMACNA HVAC Duct Construction Standard. All
transverse edges, or any edges exposed to airflow, must be
coated with an approved duct liner coating material, such as
