S. 1.4 SYSTEM DESCRIPTION Use this article carefully; restrict statements to describe components used to assemble the system. Do not repeat statements made if the Section includes article in Part 1, Section 1.1. A. Aluminum curtain wall assembly consists of tubular aluminum framing sections with deep polyamide isobar for thermal separation and glazed with screw applied exterior retainers covered with finished faces . System is shop fabricated with internal reinforcing as needed, anchorage, attachment devices, and related flashings. Fabrication and erection of the glazed frame assembly is usually left to the prerogative of the assembly fabricator. If site conditions, opening tolerances or quality of the work may be an issue or a concern, it may be prudent to require either shop assembly or field erection of the frame assembly. Select one of the following options as appropriate. B. Frame Assembly: [Stick built or site assembled.] [Shop assembled in ladder frames.] C. 1.5 PERFORMANCE REQUIREMENTS Use this article carefully; restrict statements to identify system performance requirements or functional criteria only. Delete paragraphs not appropriate to project. Performance specifying permits system manufacturers the latitude to adjust proprietary systems to achieve specified requirements. Rely on this article as the basis for assembly criteria specifying and minimize the material and component statements so not to conflict with performance criteria. If more stringent criteria are being considered, refer to AAMA and ASTM test methods and associated documents for guidance or consult with Pittco representative. A.
