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.
1.03SYSTEM 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.Unit Skylight 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. 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 unit skylights 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.
1. Design framing and dome infill assembly to support the following load requirements:
a.[30] [40]-psf snow load plus dead load.
b.[30] [40]-psf negative wind or uplift load plus dead load.
2. Fabrication and installation of unit skylights shall comply with governing building code.
