PERFORMANCE REQUIREMENTS
Compliance with AAMA/WDMA/CSA 101/I.S.2/A440, as indicated in "Unit Skylight Standard"
Paragraph below, is required by the International Building Code.
Other acceptable code authorities recognized are ASHRAE 90.1 and well as the IECC, please check your
local jurisdiction to see which code is recognized and/or acceptable.
A.
Unit Skylight Standard: Comply with AAMA/WDMA/CSA 101/I.S.2/A440 for definitions and
minimum standards of performance, materials, components, accessories, and fabrication unless
more stringent requirements are indicated.
Retain one of two "Performance Class and Grade" subparagraphs below. Class R unit skylights are
commonly used in one- and two-family dwellings; Class CW unit skylights are commonly used in lowand mid-rise commercial buildings. The performance grade (PG) designation is approximately equal to
the design load in pounds per square foot (Pascals) induced by wind and/or static snow loads acting in a
downward direction. See "AAMA/WDMA/CSA 101/I.S.2/A440" Article in the Evaluations for additional
discussion.
Reference ICC test report 3177 for performance grade of Bristolite Unit Skylights.

2.
Performance Class and Grade: Class R-PG <Insert performance grade>.
Performance Class and Grade: Class CW-PG <Insert performance grade>.
Currently, few manufacturers participate in the labeling program required by "Certification"
Subparagraph below. Product test reports from a qualified independent testing agency that are acceptable
to the building official may take the place of a certification label in some jurisdictions; verify with
authorities having jurisdiction.
3.
Certification: AAMA-, WDMA-, or CSA-certified unit skylights with label attached to
each.
Retain "Thermal Transmittance" Paragraph below if required to comply with requirements of authorities
having jurisdiction. Options are based on ENERGY STAR and National Green Building Standard
requirements. Requirements vary according to climate zone.
NFRC was developed primarily for the window industry and therefore the testing requirements for U
Factor and Solar Heat Gain Coefficient are based on the particular glazing submitted for testing, however
there is no current requirement by NFRC for Visible Light Transmission to correspond with the published
U Factor and SHGC, therefore the NFRC requirement for unit skylights is for all intents and purposes not
applicable. There must be a corresponding ASTM D 1003 Visible Light Transmission test for the product
tested or the U Factor and SHGC is meaningless. That being said, we recommend the requirement for U
Factor and SHGC be that the skylights must be tested in an NFRC Laboratory and to NFRC standards,
but not required to be listed and labeled.
Insert U Factor Value in "Thermal Transmittance" paragraph below based on specific product selected in
"Unit Skylights" Article (2.3) below.

in "Unit Skylights" Article (2.3) below.

Solar Heat-Gain Coefficient (SHGC): NFRC 200 maximum SHGC of <Insert value>.
OITC, in "Outside-Inside Transmission Class (OITC)" Paragraph below, is a noise-reduction rating based
on a sound-frequency range representative of conditions to which the building envelope is subject, such as
road, rail, and airplane traffic noise.
Retain "Outside-Inside Transmission Class (OITC)" paragraph below if applicable to skylight specified of
for a specific project.
D.
Outside-Inside Transmission Class (OITC): Rated for not less than [22] [26] [30] <Insert
value> OITC when tested for laboratory sound transmission loss according to ASTM E 90 and
determined by ASTM E 1332.
Retain "Windborne-Debris-Impact Resistance" Paragraph below if required for Project. The IBC defines
windborne debris regions. Enhanced protection applies to essential facilities. Verify requirements of
authorities having jurisdiction.
E.
Windborne-Debris-Impact Resistance: Provide unit skylights that pass [basic] [enhanced]protection testing requirements in ASTM E 1996 for [Wind Zone 1] [Wind Zone 2] [Wind
Zone 3] [Wind Zone 4] when tested according to ASTM E 1886. Test specimens shall be no
smaller in width and length than unit skylights indicated for use on Project and shall be installed
in same manner as unit skylights indicated for use on Project.
Retain first "Large-Missile Test" Subparagraph or "Small-Missile Test" Subparagraph below, or retain
second "Large-Missile Test" Subparagraph. First two subparagraphs are requirements stated in the IBC;
third is requirement in ASTM E 1996 for essential facilities.
