SECTION 08520 1200 SERIES FIXED BULL-NOSE THERMAL WINDOWS

PART 1 GENERAL

Note re USING THIS DOCUMENT: All text within boxes offers assistance with project-specific choices required to complete this Specification. Please delete these boxes prior to publication. All underlined spaces or text between brackets -- eg: (___) -- must be completed by the Specifier to suit project’s requirements.

Note re FIXED THERMAL WINDOWS: 1200 Series is available in five frame depths (4”, 5-1/8”, 6”, 7” and 8” nominal). Standard perimeter framing style (“default characteristic”) includes ¾” jambs and head, with 1” draining sill, and 1” mullions. Principal option within 1200 Series family is “long-leg” perimeter sections (1-3/4” face ) normally used with receptor systems. Other options include closed-back 1” perimeters, “flush-faced” mullions, numerous add-ons, etc.

Note re OPTIONAL SYSTEMS: This window is of a “bull-nose” profile, whereby the glazing fin is set back from the outside face by approximately 1-3/8”. Other thermal window systems include the 4100 Series Flush-Wall, with glazing fin at the exterior face, and the 4500 Series Strip-Wall, which closely resembles a curtainwall (glass is recessed but compression face is squared-off to the glazing sightline).

Note re OPERABLE WINDOWS: 1200 Series is the most versatile of the many available fixed window profiles, in that it mulls with all operable window styles. Specifically, these are 1208 Series Thermal Sliders, 1250 Series Acoustic Sliders, 1207 Series Thermal Hung, and 5100 Series Acoustic Hung. Also, the 1200 Series system will accept all projecting ventilator systems (2000 and 2250 Series) as will most of the other fixed window and curtainwall systems offered.

1.4 STRUCTURAL PROPERTIES

Note re DESIGN WIND PRESSURE: Using the latest ASCE 7 document ( as referenced by model codes such as BOCA, IBC, etc ), Specifier should determine positive and negative design wind pressure, and insert in 1.04.A. Specifier also must list all other requirements. Bid Documents (especially elevation drawings) should highlight areas of the building envelope where more severe loads, or “hot-spots”, occur. Note that deflection limits ( eg: L/175 but less than 3/4” ) may vary between locations and jurisdictions.

A. DESIGN WIND PRESSURE: Design wind pressure for this project is (__) psf inward acting pressure, and (___) psf outward acting pressure. B. UNIFORM LOAD DEFLECTION: The maximum allowable deflection of any principal member in a direction normal to the plane of the wall when subjected to the specified design wind pressure is (L/__) of its unsupported span, but not more than (__) inch. Where plastered, dry-walled, or other materials or components that will be impaired by the normally allowable deflection are attached, deflection shall not exceed (__) inch at those locations. C. UNIFORM LOAD STRUCTURAL: When subjected to uniform loads equal to 1.5 times design wind pressure, the window system shall display no glass breakage or displacement related to the imposed load; no damage to fasteners or anchors; and no permanent deformation of any principal member impairing the function of the system. D. DEAD LOAD: Deflection of any principal member in a direction parallel to the plane of the wall, when carrying its full dead load, shall not reduce glass bite below 75% of the design dimension; and the member shall have a 1/8” minimum clearance between itself and the top of the adjacent materials below. Clearance between a member and operable window or door shall be at least 1/16”. E. LIVE LOAD: The window system and its anchorage shall accommodate a deflection at mid-point between columns of (___) inch caused by uniform and concentrated live loads on floors or load-bearing elements to which the system is anchored.

1.5 QUALITY ASSURANCE A. MANUFACTURER: System shall be completely fabricated by the approved Manufacturer. All glazing shall be factory installed. B. WINDOW CONTRACTOR: Window Contractor shall possess and shall demonstrate ongoing expertise with work of similar or greater scope over a period of at least 5 years. Supply supporting references upon request.

Note re PROJECT-SPECIFIC TESTING: Mock-up testing and field testing offer good value, particularly in cases where configurations are complex, the project is large, conditions are severe, or if there is significant custom product development. In addition, “visual” mock- up(s) may be specified; these should include correct finishes and glazing. In all cases, Specification must elaborate quantity and particulars of specimen(s); state which window(s), which tests, test pressure, assumption of cost, etc. AAMA 502 is a widely recognized testing protocol; unless otherwise specified, its default parameters will be assumed.

C. OPTIONAL CLAUSE: Field Testing (OR Mock-Up Laboratory Testing OR Visual Mock-Ups): Window Contractor shall have tested (specify quantity) window in accordance with AAMA 502 Voluntary Specification for Field Testing of Windows and Sliding Glass Doors, using Test Method A, and as follows: (______). Window Contractor shall be responsible for cost of supply and installation of the specimen(s). The Owner shall be responsible for all other costs. The specimen(s) shall not be part of the completed project, except at the Owner’s sole discretion. The Manufacturer and the Window Contractor reserve the right to receive reasonable notification regarding, and to attend, all tests.

1.6 SUBMITTALS A. STANDARD LABORATORY TESTING: Submit documentation certifying compliance with AW-65 Performance Grade, in accordance with ANSI-AAMA-NWWDA 101/I.S.2-97 Standard, and based on full-height one-lite Gateway Size 60” x 96”
