DEFINITIONS:
Board Insulation: Semi-rigid insulation preformed into rectangular units having a degree of
suppleness particularly related to their geometrical dimensions. Typical materials include, but are not
limited to fiberglass, expanded polystyrene (EPS), extruded polystyrene (XPS), polyisocyanurate, or
polyurethane. The product may or may not be faced.
Facing: A thin covering adhered to the surface of insulation prior to field installation. Facings may
include, but are not limited to kraft paper, metal foil, or polymer.
R-value: The inverse of the time rate of heat flow through a body from one of its bounding surfaces to
the other surface for a unit temperature difference between the two surfaces, under steady state
conditions, per unit area. For the purposes of this program, Imperial units will only be accepted [(h · ft2
·°F)/Btu].
Smoke-Development Index: The characteristic of a material to emit smoke when exposed to flame or
fire compared to red oak and inorganic cement.
Flame-Spread Index: The characteristic of a material to resist the spreading of flames when exposed
to flame or fire compared to red oak and inorganic cement.
TEST LABORATORIES:
The laboratories that have conducted this testing were ISO 17025 accredited at the time of testing.
PRODUCT:
The products covered by this report consisted of polyisocyanurate.
The products are 0-15% by weight 1-1, -dichloro-1-flueoroethane, 0-2% by weight
chlorodifluoromethane, 0-10% by weight cyclopentane, 0-8% by weight tris (monochloropropyl)
phosphate and less than 25% by weight fibrous glass. The remaining components of this product
are non-hazardous or are in small enough quantity as to not meet regulatory thresholds for
disclosure. These components contain no substances or impurities which would influence the
classification of this product.
USE / PREPARATION / INSTALLATION:
EnergyGuard™ rigid foam insulation is intended for use as re-siding, vaulted ceilings, interior
basement walls, exterior masonry walls, interior stud walls, and exterior stud walls.
Installation Instructions attached as Appendix A, show detailed methods of application and finishing.
Also included are detailed installation instructions and diagrams that meet the criteria set forth in the
Seal and Insulate with ENERGY STAR Partnership Commitments.
THERMAL RESISTANCE:
Tests were conducted in accordance with ASTM C518-10, Standard Test Method for Steady-State
Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus. Aging of the sample
was in accordance with ASTM C1289.
The R-Value test results were calculated by ATI, covered in Evaluation Report CCRR-0197. The

Laboratories' representative such that no verification of composition can be provided. The results
relate only to items tested.
SURFACE BURNING CHARACTERISTICS:
The tests were conducted in accordance with the latest version of Standard ANSI/UL 723, “Test for
Surface Burning Characteristics of Building Materials” (ASTM E84-12) at the time of testing. There
have been no substantive, technical changes made between the version at time of test and the 2012

GAF EnergyGuard™ Polyiso Wall Sheathing
Personal Protective Equipment (PPE):



Always use appropriate Personal Protective Equipment (PPE) for safety when
handling and installing EnergyGuard™ Polyiso Wall Sheathing such as safety
hardhat, eye wear, gloves, dusk masks, appropriate clothes and boots.
Installation of a wall sheathing system is a construction process. As with any
construction process, safety is a key element. All applicable safety standards and
good roofing practices must be followed.
Always comply with all OSHA safety standards, fire codes and local code
requirements.
Site Preparation:
General: No manufacturer trained or certified installer is required for the
installation of GAF EnergyGuard™ Polyiso Wall Sheathing.





Work shall only begin when the substrates have been prepared as necessary,
and are ready and acceptable to have materials installed as specified. Providing
a smooth, even, sound, clean and dry substrate minimizes the likelihood that
underlying deficiencies will cause premature deterioration or even failure of the
wall sheathing.
Sheathing should be properly stored and weighted to avoid weather and wind
damage.
Do not install materials during inclement weather, except for temporary work
necessary to protect materials that are already installed. Remove all temporary
work before installing permanent materials.
Do not install materials when moisture, in any form, is present within the material
or on the substrate to which the materials are to be applied. Remove and replace
any wet or damaged materials prior to the installation of GAF EnergyGuard™
Polyiso Wall Sheathing.
There are no requirements for re-entry or re-occupancy times.

Vaulted/Cathedral Ceilings… General Application Instructions:





Cut the EnergyGuard™ Polyiso Wall Sheathing boards to fit snugly between the
roof rafters.
Install the boards between the bottom sides of the roof rafters making sure the
boards stop flush.
Run the boards continuously without gaps the
entire length of the vaulted ceiling, starting from
the top or bottom.
The thickness of the EnergyGuard™ Polyiso Wall
Sheathing boards should be such so that when
they are installed flush with the bottom of the roof
rafters, there is a continuous air space between the top of the Polyiso boards
and the bottom of the roof deck. This gap is to provide enough net-free
continuous air space from the soffit vents up to the ridge vent so it does not
restrict air flow. For proper ventilation requirements, refer to local building code
or roofing manufacturer’s guidelines.
Polyiso board joints are to be in contact with each other, with the printed side
facing the interior.




Seal all interior openings and penetrations with all-weather sealant, such as
silicone caulk, prior to taping. Make sure all areas are clean prior to sealing and
taping to ensure proper adhesion.
Center and apply 3” (76 mm) wide foil flashing tape to
all board joints, penetrations and skylight flanges. Apply
tape and sealant in accordance with the manufacturer’s
application instructions.
Always cover EnergyGuard™ Polyiso Wall Sheathing
with a code-approved interior cladding system, such as
½” (13 mm) gypsum board. The gypsum boards or other interior cladding system
should be installed in accordance with the appropriate manufacturer’s
application instructions.
In areas of high humidity or as required by local code, install a vapor retarder.
