This section includes the following: <br />1. Curb-mounted plastic glazed barrel vault skylights. <br />a. Double dome, thermalized, barrel vault, with vertical ends. <br />B. Related Sections: The following sections contain requirements that relate to this section: <br />1. Division 7 Section Sheet Metal Flashing and Trim. <br />2. Division 7 Joint Sealants. <br />3. Division 7 Non Permeable Air and Vapor Barrier <br /> <br />C. Refer to roofing system sections for roofing accessories to be built into the roofing system to accommodate <br />work of this section. <br /> <br />1.2 PERFORMANCE REQUIREMENTS <br /> <br />A. General: Provide unit skylights capable of withstanding loads as defined by the local codes having <br />jurisdiction where units are to be installed without failure. Failure includes the following: <br /> <br />1. Thermal stresses transferred to the building structure. <br />2. Framing members transferring stresses, including those caused by thermal and structural <br />movement, to glazing. <br />3. Weakening of fasteners, attachments, and other components. <br /> <br />B. Structural Performance: Provide metal-framed skylights, including anchorage, capable of withstanding <br />design pressure indicated without material and deflection failures and permanent deformation of structural <br />members exceeding 0.2 percent of span when tested according to ASTM E 330-97. <br />1. Design Test Pressure: 40 PSF positive and 40 PSF negative. <br />C. Air Infiltration: Provide metal-framed skylights with maximum air leakage of 0.09 scfm/sq. ft. of surface <br />when tested according to ASTM E 283-91 at a minimum static-air-pressure differential of 6.20psf. <br />D. Water Penetration: Provide metal-framed skylights that do not evidence water penetration when tested <br />according to ASTM E 331-00 and E 547-00 at a minimum differential static pressure of 20 percent of <br />positive design wind load, but not less than 8psf. <br /> <br /> <br /> <br />1.3 SUBMITTALS <br /> <br />A. Product Data Sheet: For each type of skylight specified, include details of construction and installation, <br />relative to applicable curb configuration. <br />B. Samples for Selection: Manufacturer’s color charts showing a full range of colors available for each type of <br />skylight glazing and Aluminum Finish. <br /> <br />1.4 QUALITY ASSURANCE <br /> <br />A. Fire-Test-Response Characteristics: Provide glazing fabricated from sheets identical to those tested for the <br />following fire-test-response characteristics, per ASTM test method indicated below, by UL or other testing <br />and inspecting agencies acceptable to authorities having jurisdiction. Identify plastic sheets with <br />appropriate markings of applicable testing and inspecting organization. <br />DocuSign Envelope ID: 51195338-6F17-4D2B-B990-4A82329E7F4E
