Specifier Note: Article below should be restricted to statements describing design or
performance requirements and functional (not dimensional) tolerances of a complete
system. Limit descriptions to composite and operational properties to extent necessary
to link multiple components of a system, and to interface with other systems.
1.3 SYSTEM DESCRIPTION
A. Performance Requirements: Provide roof accessories which have been
manufactured, fabricated and installed to withstand loads from [Specify
code/standard reference] and to maintain [Specify performance criteria]
performance criteria stated by manufacturer without defects, damage or failure.
B.
Roof Accessories Performance Requirements:
Specifier Note: Edit Performance Requirements paragraph below for loads to suit project
requirements. Roof accessories are commonly used in low-rise construction where roof
elevations do not exceed 60 feet above grade. Roof accessories should be designed to support
a minimum 20 psf snow load and a negative pressure or uplift of 20 psf. Greater capacities may
be required depending on code requirements or project location. Plastic glazing materials are
not designed to support live loads or concentrated impact type loads. "Risk of fall" label is
applied to each dome to warn of potential danger. (1) Performance Requirements: Referenced
standards establish the level of quality of roof accessories available from quality manufacturers
conforming to industry standards. (2) Condensation: Under certain conditions of high humidity
and/or large inside to outside temperature differentials, condensation may occur on the
aluminum framing and plastic glazing material. Thermally broken frames can be specified to
help control compensation on aluminum framing. Double glazing will usually reduce the
occurrence of condensation on the plastic, but will not totally eliminate it. The condensation that
forms between the double layers of plastic will normally dissipate as the airspace is heated by
the sun. Sealed domes are more resistant to the formation of condensation and will reduce
accumulation of dust and foreign matter. Sealed domes are available for most dome glazed unit
skylights at additional cost.
Specifier Note: Edit paragraph below. Specify values, minimum 20 psf recommended. For
Double Leaf Mechanical Heat and Smoke Vents (Part 2 Products) 30 psf required for listed
units.
1. Design framing and dome infill to support the following load requirements:
a.
b.
a.
b.
[Specify] PSF snow load plus dead load.
[Specify] PSF negative wind or uplift load plus dead load.
2. Labeled smoke vents should conform to the approval guidelines of either UL
or FM.
3. Fabrication and installation of roof accessories shall comply with NRCA
recommendation that the top of curb to finish roofing dimension be a minimum
of 8" (203.2 mm).
Specifier Note: Article below includes submittal of relevant data to be furnished by
Contractor either before, during, or after construction. Coordinate this article with
