AP Armaflex® Pipe Insulation and
AP Armaflex SS Self-Seal Pipe Insulation
Proven Performance Leader
DESCRIPTION
Mold resistant AP Armaflex and AP Armaflex
SS Self-Seal Pipe Insulations are 25/50-rated
flexible elastomeric thermal insulations, black
in color, supplied as tubing in popular sizes up
to 6″ IPS. (See wall thicknesses, next page.)
The expanded closed-cell structure of AP
Armaflex makes it an efficient insulation. It is
manufactured without the use of CFC’s,
HCFC’s, or HFC’s. It is also formaldehyde
free, low VOCs, dust free, fiber free and
resists mold and mildew. All AP Armaflex
products are made with Microban® antimicrobial product protection for added defense
against mold on the insulation.
AP Armaflex Pipe Insulation, through 1-1/2″
wall thickness has a flame-spread index of
less than 25 and a smoke-developed index of
less than 50 as tested by ASTM E 84.
AP Armaflex and AP Armaflex SS are
approved through continuing supervision by
Factory Mutual Approvals and consistently
provide actual values on these key performance criteria for mechanical system insulation:
Thermal Conductivity: 0.27 BTU-in/hr. ft2 °F
Water Vapor Permeability: 0.08 perm-inch
Fire Rating: will not contribute significantly
to fire (simulated end use testing)
Factory Mutual Approvals has determined that
AP Armaflex will not contribute significantly to
fire through tests deemed more predictive of
end use performance than ASTM E 84.
Factory Mutual Approvals supervision
includes continuing testing by these methods:
UBC 26-3 Room Fire Test Method and the
Factory Mutual Approvals Full Scale
Horizontal Simulated Pipe Chase Test.
Numerical flammability ratings alone may not define
the performance of products under actual fire conditions. They are provided only for use in the selection
of products to meet limits specified.
USES
AP Armaflex Pipe Insulations are used to
retard heat gain and control condensation
drip from chilled water and refrigeration
systems. They also efficiently reduce heat flow
for hot-water plumbing and liquid-heating and
dual-temperature piping. (See chart next page
for recommended temperature usage range.)
For use on cold pipes, AP Armaflex
thicknesses have been calculated to
control condensation on the insulation
outer surface, as shown in
the table of thickness
recommendations.
AP Armaflex and AP Armaflex SS meet the
energy code requirements of ASHRAE 90.1,
ASHRAE 90.2, IECC and other building
codes
RESISTANCE TO MOISTURE VAPOR
FLOW
The closed-cell structure of AP Armaflex
Insulation prevents moisture from wicking and
makes an efficient insulation. AP Armaflex is
considered a low-transmittance vapor
retarder. AP Armaflex normally requires no
supplemental vapor-retarder protection.
Additional vapor-retarder protection may be
necessary for AP Armaflex when installed on
very low temperature piping or where
exposed to continually high humidity
conditions.
APPLICATION
AP Armaflex Pipe Insulation in unslit tubular
form can be slipped onto piping before it is
connected, or it can be slit lengthwise and
snapped over piping already connected.
Apply AP Armaflex SS Insulation by placing
the slit tubing over pipe. Peel release liners
from adhesive surfaces and apply firm pressure along entire longitudinal joint. Secure
butt ends using Armaflex 520, 520 Black
Adhesive or, where a low V.O.C. adhesive is
required, Armaflex 520 BLV Adhesive.
Fitting covers may be fabricated from
mitered-cut AP Armaflex Self-Seal tubing.
Fabricate miter-cut fitting covers and assemble with Armaflex 520, 520 Black or 520 BLV
Adhesive. Install over pipe fitting and seal to
adjoining sections of pipe insulation with 520,
520 Black or 520 BLV Adhesive. 520
Adhesives are contact adhesives; therefore, in
all cases, both surfaces to be joined are coated with adhesive.
For pipes greater than 6″ IPS, use
AP Armaflex Sheet/Roll insulation. For
thicknesses greater than 1″, sleeve the
insulation. See technical bulletin #30 for additional information. The AP Armaflex pipe insulation is available in 1-1/2″ wall thickness with
25/50 rating for ID size range from 7/8″ to 4″
IPS.
AP Armaflex is designed for installation above
ground. Indoors, no protective finish is
required. Outdoors, a weather-resistant
protective finish is to be applied. The
recommended protective finish is Armaflex
WB Finish; however, other compatible finish
systems are not ruled out.
SPECIFICATION COMPLIANCE
AP Armaflex developed to meet:
AP Armaflex
insulation is
acceptable in wall
thickness through 1-1/2″
(38mm) for use in air plenums.
Conforms to NFPA 90A and 90B
requirements.
www.armacell.com
NOTE: Armaflex insulation products must be installed according
to “Installation of Armaflex Insulations.” Proper installation is
required to assure Armaflex insulation performance.

AC Accoflex® Coil
Longer, UV Retardant,
Less Waste
TECHNICAL DATA
FM
APPROVED
F
DESCRIPTION
AC Accoflex Coil is a system designed for
convenience and labor savings, with bestin-class UV retardance. It is provided in
continuous-length coils, designed to minimize
waste and reduce butt joints, and packaged in easyhandle, easy-store cartons. The pipe insulation is tough but
flexible elastomeric thermal insulation, black in color, supplied as
continuous-length unslit tubing in nominal wall thicknesses of 3/8″
(10mm) and 1/2″ (13mm) in popular sizes up to 1-1/8″ ID. Its closed
cell structure prevents moisture from wicking and makes it an efficient
insulation. It is manufactured without the use of CFC’s, HCFC’s or
HFC’s. It is also formaldehyde free, fiber free, dust free and resists
mold and mildew.
USES
AC Accoflex Coil is used to retard heat gain and control condensation
drip from chilled water and refrigeration systems. It also efficiently
reduces heat flow on hot systems. AC Accoflex is engineered for air
conditioning applications in which speed, ease of installation,
convenient handling and on-site durability are of primary importance.
AC Accoflex Coil is acceptable for use in air plenums. Conforms to
NFPA 90A and NFPA 90B requirements.
INSTALLATION
AC Accoflex uncoils easily from its convenient carton, so it can be cut
to desired lengths for longer runs with fewer seams. It also slides on
the pipe easier. The specially formulated lubricating powder effectively
reduces friction, and relaxed I.D. tolerances accommodate elbows and
fittings. Installs with simple hand tools and Armaflex 520, 520 Black
Adhesive or, where a low V.O.C. adhesive is required, Armaflex 520 BLV
Adhesive.
AC Accoflex Coil is approximately 2x easier to apply to typical piping
than standard AC Accoflex.

AP Armaflex® Sheet & Roll Insulation and
AP Armaflex SA Self-Adhering Sheet &
Roll Insulation
Proven Performance Leader
DESCRIPTION
Mold resistant AP Armaflex and AP Armaflex
SA Self-Adhering Sheet and Roll Insulation are
flexible, elastomeric thermal insulations, black
in color. Both are supplied in flat sheets 36″ x
48″ (.92m x 1.22m), in popular thicknesses. AP
Armaflex and AP Armaflex SA are also
available in 48″ (1.22m) continuous rolls in 3/8″,
1/2″, 3/4″, 1″, 1-1/2″ and 2″. It is also available
in 60″ (1.53m)
in 1″ wall thickness. (See sizes and metric
conversions, next page). The insulations are
furnished with a smooth skin one side which
forms the outer exposed insulation surface.
The expanded closed-cell structure of Armaflex
makes it an efficient insulation. It is
manufactured without the use of CFC’s,
HCFC’s or HFC’s. It is also formaldehyde free,
low VOCs, dust free, fiber free and resists mold
and mildew. All AP Armaflex products are
made with Microban® antimicrobial product
protection for added defense against mold on
the insulation.
As tested by ASTM E 84, “Method of Test for
Surface Burning Characteristics of Building
Materials,” AP Armaflex Sheet Insulations in
thicknesses through 2″ (50mm) have a flamespread index of less than 25 and a smokedeveloped index of less than 50.
AP Armaflex is approved through continuing
supervision by Factory Mutual Approvals and
consistently provide actual values on these key
performance criteria for mechanical system
insulation.
Thermal Conductivity: 0.27 BTU-in/hr sq.ft. °F
Water Vapor Permeability: 0.08 perm-inch
Fire Rating: Will not contribute significantly to fire.
(simulated end-use testing)
Factory Mutual Approvals has determined that
AP Armaflex will not contribute significantly to
fire through tests deemed more predictive of
the end use performance than ASTM E 84.
Factory Mutual Approvals supervision
includes continuing testing by these
methods: UBC 26-3 Room Fire Test
Method and the Factory Mutual
Approvals Full-Scale Horizontal
Simulated Pipe Chase Test.
Numerical flammability ratings alone may
not define the performance of products
under actual fire conditions. They are
provided only for use in the selection of
products to meet limits specified.
USES
AP Armaflex is used to retard heat gain and
control condensation drip from chilled water
and refrigeration systems. It also efficiently
reduces heat flow on hot systems.
AP Armaflex Sheet/Roll Insulations are
particularly adaptable for insulating ductwork,
large piping and fittings, tanks, and vessels.
Their flexibility allows application to curved and
irregular surfaces. They are very adaptable to
making all types of fitting cover insulations.
www.armacell.com
The recommended temperature usage range
for AP Armaflex Sheet Insulation is -297°F to
+220°F (-183°C to +105°C) according to
method of application. AP Armaflex sheet with
full adhesive coverage, and AP Armaflex SelfAdhering Sheet, may be used on surfaces with
operating temperatures up to 180°F (82°C).
When used for pipe insulation with adhesive
adhering seams and joints only, Armaflex Sheet
can be applied to lines that will operate to a
limit of 220°F (105°C).
For use on cold surfaces, AP Armaflex
thicknesses have been calculated to control
condensation on the insulation outer surface, as
shown in the table of thickness
recommendations.
RESISTANCE TO MOISTURE VAPOR FLOW
The closed-cell structure of Armaflex Insulations
prevents moisture from wicking and makes it an
efficient insulation. For many applications,
Armaflex needs no supplementary protection.
Additional vapor-retarder protection may be
necessary for Armaflex when install on very
low-temperature surfaces or piping or where
exposed to continually high humidity conditions.
APPLICATION
AP Armaflex Sheet is installed using Armaflex
520, 520 Black Adhesive or, where a low V.O.C.
adhesive is required, Armaflex 520 BLV
Adhesive. For application to large flat or curved
metal surfaces such as ducts, very large pipes,
tanks, and vessels, full adhesive coverage is
used. For applications as pipe insulation and
fitting covers, only the seams and joints are
adhered with adhesive. 520 Adhesives are
contact adhesives; therefore, in all cases, both
surfaces to be joined are coated with adhesive.
Exterior ductwork must be pitched to allow
rainwater to run off the insulation.
AP Armaflex Self-Adhering Sheet has a factoryapplied adhesive system with long-term
performance similar to 520 Adhesive. It can be
applied to clean, non-oily metal surfaces.
Simply remove a portion of the release liner,
position sheet, adhere one edge, and then just
peel and press. Seams and joints are adhered
using 520, 520 Black or 520 BLV Adhesive.
AP Armaflex Sheet and Self-Adhering Sheet
insulations are designed for installation above
ground. Indoors, no protective finish is required.
Outdoor, a weather-resistant protective finish is
to be applied. The recommended protective
finish is Armaflex WB; however, other
compatible finish systems are not ruled out. For
exterior applications, consider maintenance-free
ArmaTuff products.
AP Armaflex and AP Armaflex SA Sheet and
Roll Insulation meet the energy code
requirements of International Energy
Conservation Code (IECC) and ASHRAE for Rvalue of 4 at 1″ wall thickness and R-value of 8
at 2″ wall thickness.

Tubolit® Pipe Insulation and
Tubolit SS Pipe Insulation
Quick & Cost Effective
DESCRIPTION
Tubolit and Tubolit Self-Seal Pipe Insulations
are 25/50-rated flexible closed-cell black
polyolefin/polyethylene pipe insulations,
supplied as semi-slit or self-seal, in nominal
wall thicknesses of 3/8″, 1/2″, 3/4″, and 1″
(10, 13, 19 and 25 mm), in the most
frequently specified sizes. Tubolit is expanded
without the use of CFC’s, HCF’s or HCFCs. It
is also formaldehyde free, low VOCs, dust
free, fiber free and resists mold and mildew.
USES
Tubolit Pipe Insulations are particularly
effective for cost-efficient thermal insulation of
domestic heating and plumbing lines. The
recommended temperature usage range for
Tubolit Insulations 0°F to +180°F (–17°C to +
82°C).
As tested by ASTM E 84, “Method of Test for
Surface Burning Characteristics of Building
Materials,” Tubolit insulations through 1″ wall
have a flame-spread index of less than 25
and a smoke-developed index of less than 50.
Tubolit and Tubolit SS meet the
energy code requirements of
ASHRAE 90.1, ASHRAE 90.2,
IECC and other building codes.
APPLICATIONS
Tubolit Pipe Insulation in tubular form is easy
to sleeve over new pipework, or cut
longitudinally to snap over existing pipework.
Tubolit Self-Seal Insulation is snapped over
new or existing pipework.
Both install with simple hand tools and
Armaflex 520, 520 Black Adhesive or, where
a low V.O.C. adhesive is required, Armaflex
520 BLV Adhesive. Butt joints should be
sealed with either 520, 520 Black or 520 BLV
Adhesive. 520 Adhesives are contact
adhesives; therefore, in all cases, both
surfaces to be joined are coated with
adhesive. Seams can be sealed with 520,
520 Black or 520 BLV Adhesive.
Tubolit and Tubolit SS must be protected
from direct sunlight exposure and weather
elements and must be protected when
installed outdoors with weather-resistant
jacketing or Armaflex WB Finish.

Armafix® Insulation Pipe Hangers
Efficient, Faster Support
DESCRIPTION
Armafix Insulation Pipe Hangers are quick,
innovative alternatives to traditional block
and dowel pipe supports. The engineered,
foam-to-foam solutions provide optimum
load bearing while protecting against
thickness compression and condensation
gaps that can compromise system integrity.
USES
Armafix is used to support insulated pipes
with pre-insulated hangers that retard heat
gain and control condensation drip from
cold-water plumbing, chilled-water and
refrigeration lines. It is engineered from
Armaflex or NH/Armaflex insulation, with
polyurethane inserts 30mils thick and
aluminum (IPH) or stainless steel (NPH)
jacket. It is single-piece construction, selfadhesive closure with exclusive foam-tofoam bond. Armafix (IPH) pipe hangers are
available in nominal 3/4″ and 1″ wall
thicknesses with ID’s ranging from 3/8″ ID to
8″ IPS. Also available in nominal 1/2″ wall
thickness by special order. Armaflex NPH:
NH/Armaflex nonhalogen insulation
formulation available in 3/4″ nominal wall
thickness with ID’s ranging from 3/8″ ID to
8″ IPS. Armaflex insulation’s thermal
conductivity resistance to moisture vapor
flow (WVT) and closed cell structure provide
for total system integrity.
APPLICATION
Armafix longitudinal seams are selfadhering. The ends are easily sealed with
Armaflex 520, 520 Black Adhesive or, where
a low V.O.C. adhesive is required, Armaflex
520 BLV Adhesive to ensure a completely
sealed system. For some applications,
saddles are recommended. To minimize the
movement of Armafix, it is recommended
that a pair of non-skid pads, be adhered to
the clamps. In addition to prevent loosening
of the clamps, use of an anti-vibratory
fastener, such as a nylon looking nut, is also
recommended.
