SECTION 08 51 69.11

ALUMINUM STORM WINDOWS

PART 1 - GENERAL

1.1 DESCRIPTION

A. Triple track, self-storing type aluminum storm windows, of sizes shown, complete with frame, sash, hardware, glass closures, and related components and accessories shown and specified.

B. Window opening sizes shown are approximate. Before fabricating storm windows, measure each opening to determine its exact size.

1.2 RELATED WORK

A. Color of Finish: Section 09 06 00, SCHEDULE FOR FINISHES.

B. Glazing: Section 08 80 00, GLAZING.

1.3 PERFORMANCE REQUIREMENTS

A. Air Infiltration: With sash closed and latched, test the window in accordance with ASTM E283 for air infiltration, which will not exceed

2.06m3/h per meter (0.37 ft3/min per foot) of operable sash when subjected to static air pressure of 75 Pa (1.57 psf).

B. Water Drainage: Test window in accordance with ASTM E331, except pressure drop to be zero, and test duration of three minutes. Unit is acceptable if no water runs over interior edge of sloped test-buck sill.

C. Uniform Load: Test window in accordance with ASTM E330. Subject the window separately to any exterior uniform load of 480 Pa (10 psf), and an interior load of 240 Pa (5 psf). Maintain each load for 10 seconds.

At conclusion of tests there cannot be evidence of breakage and test unit must operate freely.

1.4 SUSTAINABILITY REQUIREMENTS

A. Materials in this section may contribute towards contract compliance with sustainability requirements. See Section 01 81 11, SUSTAINABLE

DESIGN REQUIRMENTS, for project local/regional materials, low-emitting materials, recycled content, requirements.

1.5 SUBMITTALS

A. In accordance with Section 01 33 23, SHOP DRAWINGS, PRODUCT DATA, AND

SAMPLES, furnish the following:

1. Shop Drawings: Indicate elevations of units, full-size sections, thicknesses and gages of metal, fastenings, methods of installations and anchorage, size and space of anchors, methods of glazing, locations of operating hardware, mullion details, method and

08 51 69.11 - 2 material of weatherstripping, method of attaching screens, details of installation, and connections with other work.

2. Manufacturer's Certificates: Stating that windows meet performance requirements specified.

PART 2 – PRODUCTS

2.1 MATERIAL

A. Aluminum, Extruded: ASTM B221; provide aluminum alloy as required to produce specified color. Colors for sheet aluminum must not deviate more than color of extrusion samples.

B. Fasteners: Except as otherwise specified, screws, bolts, nuts, rivets and other fastening devices incorporated in windows to be of aluminum, stainless steel or other noncorrosive material compatible with aluminum which will provide required strength at connections. Plated or coated materials (except for glazing clips) will not be acceptable.

08 51 69.11 - 3

1. Where type, size or spacing of fastenings for securing window accessories or equipment to building construction is not shown or specified, use expansion or toggle bolts or screws, as best suited to construction material. Provide such bolts or screws minimum 6 mm

(1/4-inch) in diameter.

2. Lead, fiber and plastic shields are not acceptable.

C. Insect Screening: Regular mesh, 18 by 16 aluminum with dark bronze anodized finish; nominal wire diameter minimum 0.25 mm (0.011 inch).

D. Sealant: ASTM C920.

2.2 STORM WINDOW

A. Storm window units to be aluminum triple-track, self-storing, horizontal sliding, combination storm-and- screen type, factory glazed;

glazed sash and screen sash housed in window frame.

B. Storm units must be designed to provide a rigid unit in place, to permit all sash to be removed from the inside, and to lock into the open and closed positions. Sash units that rattle when operated or when subjected to wind conditions are not acceptable.

2.3 FABRICATION

A. Glazed sash to have aluminum frames, removable vinyl glazing inserts, interlocking meeting rails, and weather stripped edge at inside contact with the unit frame.

B. Screen sash to have aluminum frames, screening removable splines of aluminum or vinyl, covering the opening formed when the glazed sash are in the open position.

C. Provide frames of extruded aluminum section, with minimum nominal material thickness of 1 mm (0.045 inch).

1. Provide interlocking scribe piece of the same material as the frame at bottom edge.

D. Hardware: Manufacturer's standard hardware securely attached, easily accessible and operable, and capable of being removed without use of special tools.
