1 7000 Series Curtain Wall Information Specifications Information All framing members shown in this section, unless noted otherwise, are stock items in dark bronze or clear anodic coatings and are available for prompt shipment. Other anodic coatings or painted finishes are also available upon inquiry. Specifications I General: Description: Pressure Plate Stick Curtain Wall ¼ &1 Schematics Work included: Furnish all necessary materials, labor and equipment for the complete installation of aluminum framing as shown on the drawings and specified herein. (Specific note: It is suggested that relative items such as glass, sealants and aluminum entrances be included whenever possible.) Work not included: Structural support of the framing system, interior closures, trim, metal sub-sills. (Specifier list under exclusions). Related work specified elsewhere: (Specifier List). Quality Assurance Drawing and specifications are based upon the 7000 series curtain wall system as manufactured by Atlas Architectural Materials, Inc.. Whenever substitute products are to be considered, supporting technical literature, samples, drawings and performance data must be submitted 10 days prior to bid in order to make valid comparison of the products involved. Test reports certified by an independent test laboratory must be made available upon request. Performance Requirements Air filtration shall be tested in accordance with ASTM infiltration shall not exceed.06 CFM per square foot of fixed area. Water filtration shall be tested in accordance with ASTM E No water penetration at a test pressure equal to 20% of the wind load but not less than 8PSF. (AAMA )

2 Structural performance shall be based on: Maximum deflection of L / 175 of the span And Allowable stress with a safety factor of 1.65 the system shall perform to these criteria under the wind load (specify) PSF II Products: Materials Extrusion shall be 6063-T5 alloy and temper per ASTM B221. Fasteners, where exposed, shall be aluminum, stainless steel or zinc plated steel in accordance with ASTM B633. Perimeter anchors shall be aluminum or steel, providing the steel is properly insulated from the aluminum. Vertical mullions shall be sufficient strength to meet job requirements mullion configurations to allow for the system to be glazed from the exterior or interior using sponge neoprene gaskets and dense neoprene wedge. Provisions shall be made at all sealed horizontals to lead moisture accumulated to exterior. A cover shall be snapped over pressure plate to show only a sharp, uninterrupted exterior profile. Finish All exposed framing surfaces shall be free of scratches and other serious blemishes. Aluminum extrusions shall be given a caustic etch followed by an anodic oxide treatment to obtain (Specify one of the following). an architectural class II dark bronze and anodic coating with color conforming to aluminum association standard AAA-M12 C22 A32/34. an architectural class II clear V204-R1 coating conforming to aluminum association standard AA-M12 C22 A31. Fabrication The framing system shall provide for a flush glazing appearance with no projecting stops. Where to go and horizontal framing members shall have a nominal dimension of two and a half inches by 7 inches overall depth of system will vary with design.

3 III Execution: Installation Per Mock-Up Example All glass framing shall be set in correct locations as shown in the details and shall be level, square, plumb and in alignment with other work in accordance with manufacturer's installation instructions and approved shop drawings. All joints between framing and the building structures shall be sealed in order to secure a watertight installation. Protecting and Cleaning After installation, the general contractor so adequately protect exposed portions of aluminum surfaces from damages by grinding and polishing compounds plaster lime acid cement or other contaminants the general contractor shall be responsible for final cleaning. IV Mock Up Description Product Type: Aluminum Curtain Wall Product Drawings, Appendix A Series Model: ½ x 7 Curtain Wall Frame Size: Width: Height: Square Footage 12-1 ¾ ( ) 27-9 (333 ) sqft Weep Arrangement: 5/16 weep hole at ¼ points of exterior pressure plate at intermediate horizontals and 5/16 weep hole at ¼ points underside of exterior horizontal face caps.

4 Please use mock-up drawings as guidance to fabricating/cutting for your opening.

5 Curtain Wall Anchorage: Aluminum T-Anchors at intermediate mullions and F anchors at jamb mullions attached to chamber steel. T-anchors attached with one (1) ½ x3 thread cutter bolt with flat and lock washer at each side of intermediate mullion. F-Anchors attached with one (1) ½ x 3 thread cutter bolt with flat and lock washer and one (1) ¼ drill flex to counter rotation. Vertical mullions inserted between two (2) 4 x6 x5/16 thick steel angles and are through bolted with one (1) ¾ 10x1 ½ grade 5 HH bolt and two flat washers. Horizontals: Horizontal-to-vertical members are shear block connected with extruded aluminum shear block attached to vertical members with three (3) #12x2 Slotted HWHSMS screws and to horizontals with two (2) #12x ½ PPHSMS screws. Sealants: Curtain wall was perimeter sealed with backer rod and Tremco Dymonic FC Polyurethane sealant. Foam rubber joint plug bed in covered with Tremco Dymonic FC silicone applied at the ends of the horizontal-to-vertical connections. Splice at jamb and intermediate vertical members sealed with bond breaker tape at the exterior face and Tremco Dymonic FC. Aluminum head and jamb perimeter adaptor bed in Tremco Dymonic sealant and attached to frame members with #10x1 screws spaced 2 from each end and on 24 centers. T and F anchors set in a bed of Tremco Dymonic sealant. Top of shear blocks sealed to vertical mullions prior to horizontal installation. Glass: Vision Glass is 1 overall thickness sealed insulating glass contructed of ¼ clear tempered glass at exterior, ½ airspace, and ¼ clear tempered glass at interior. Spandrel glass is ¼ clear tempered glass. Curtain Wall Glazing: Glass is zone dammed exterior glazed with pressure plat mechanically fastened to the verticals and horizontals with #14-14x1 HWH screws (Part #9707) spaced on 2 and 5 from each end and on 10 centers. Part #9700 EPDM Pre-set gasket at the interior and exterior face of glass. PVC thermal isolator part#9701 gasket at the interior face of pressure plate in-line with the frame fastener race. Aluminum glazing adaptor at the interior of spandrel glass sealed to frame members with Tremco Dymonic FC sealant. V. Test Equipment

6 5.1 Test chamber of structural steel beams, columns and bulkheads and was accessible through a bulkhead door. 5.2 Pressure differentials were created with reversible pumps for positive/negative loading. 5.3 Pressure differentials between the specimen interior and the atmosphere were measured with manometers. 5.4 Air infiltration was measured with a Meriam laminar flow element and inclined manometers. Chamber pressure was measured with a Dwyer inclined manometer. 5.5 Water was applied to the specimen from a spray rack equipped with swirl-type nozzles spaced two feet on center in vertical and horizontal directions, which under controlled pressure, delivered a minimum of five gallons per square foot per hour on the specimen. 5.6 Dynamic Winds generated from a Continental 150 aircraft engine. 5.7 Structural variations were measured with Chicago Dial gauges with maximum movement hands located throughout the test specimen. VI. Testing Allowable 6.1 Air Infiltration: Total amount of air infiltration shall not exceed.06 CFM per square foot (PSF) of the exterior wall tested. Mock-Up: 12-1 ¾ x27-9 = sqft x.06cfm = 20.22cfm 6.2 Static Water Penetration: There shall be no uncontrolled water penetration during or at the conclusion of this test at the static pressure of 12psf. 6.3 Dynamic Water Penetration: There shall be no uncontrollable water penetration during or at the conclusion of this test at the slipstream velocity of 69mph, equivalent to 12psf. 6.4 Design Load Deflections: There shall be no system failure and deflection of aluminum members at 100% of design load and shall not exceed L/125 for spans up to Proof Load Residual: The permanent deformation of the aluminum members shall not exceed 0,2% of span at 150% of design load. VerticalSpan (L): /500 =.333 / Horizontal Span (L): 45.25/500 = 0.09

7 Note: Uncontrolled water is defined as any water that appears on any normally exposed interior surfaces, that is not contained or drained back to the exterior, or that can cause damage to adjacent materials or finishes. Water contained within drained flashings, gutters, and sills is not considered water leakage. The collection of up to one half (1/2) ounce of water (14.8 cc) ina fifteen (15) minute period on top of any interior stop or stool integral with the wall system shall not be considered water leakage.
