Louver Screen Frames: Fabricate with mitered corners to louver sizes indicated. 1. Metal: Same type and form of metal as indicated for louver to which screens are attached. Reinforce extruded-aluminum screen frames at corners with clips. 2. Finish: Mill finish unless otherwise indicated. 3. Type: Non-rewirable, U-shaped frames. D. Louver Screening for Aluminum Louvers: 1. Insect Screening: Aluminum, 18 x 16 mesh inch wire. 2. Bird Screening: Flattened, expanded aluminum, 5/8 inch x.040 inch in removable frame.

22 1. Thickness: 1 inch (25 mm). 2. Metal Facing Sheets: Galvanized-steel sheet, not less than inch (0.71-mm) nominal thickness. 3. Insulating Core: Rigid, glass-fiber-board insulation or extruded-polystyrene foam. 4. Edge Treatment: Trim perimeter edges of blank-off panels with louver manufacturer's standard channel frames, with corners mitered and with same finish as panels. 5. Seal perimeter joints between panel faces and louver frames with gaskets or sealant. 6. Panel Finish: Same type of finish applied to louvers, but black color. 7. Attach blank-off panels with sheet metal screws. 2.6 MATERIALS A. Aluminum Extrusions: ASTM B 221 (ASTM B 221M), Alloy 6063-T5, T-52, or T6. B. Fasteners: Use types and sizes to suit unit installation conditions. 1. Use hex-head or Phillips pan-head screws for exposed fasteners unless otherwise indicated. 2. For fastening aluminum, use aluminum or 300 series stainless-steel fasteners. 3. For color-finished louvers, use fasteners with heads that match color of louvers. 2.7 FABRICATION A. Factory assembled louvers to minimize field splicing and assembly. Disassemble units as necessary for shipping and handling limitations. Clearly mark units for reassembly and coordinated installation. B. Maintain equal louver blade spacing to produce uniform appearance. C. Fabricate frames, including integral sills, to fit in openings of sizes indicated, with allowances made for fabrication and installation tolerances, adjoining material tolerances, and perimeter sealant joints. 1. Frame Type: Channel unless otherwise indicated. D. Include supports, anchorages, and accessories required for complete assembly. E. Provide subsills made of same material as louvers for recessed louvers. F. Join frame members to each other and to fixed louver blades with fillet welds, threaded fasteners, or both, as standard with louver manufacturer unless otherwise indicated or size of louver assembly makes bolted connections between frame members necessary. 2.8 ALUMINUM FINISHES A. Finish louvers after assembly. B. Color Anodic Finish: AAMA 611, AA-M12C22A42/A44, Class I, mm or thicker. 1. Color: As selected by Owner from manufacturers full range of colors. FIXED LOUVERS

23 PART 3 - EXECUTION 3.1 EXAMINATION A. Examine substrates and openings, with Installer present, for compliance with requirements for installation tolerances and other conditions affecting performance of the Work. B. Proceed with installation only after unsatisfactory conditions have been corrected. 3.2 PREPARATION A. Coordinate setting drawings, diagrams, templates, instructions, and directions for installation of anchorages that are to be embedded in concrete or masonry construction. Coordinate delivery of such items to Project site. 3.3 INSTALLATION A. Locate and place louvers level, plumb, and at indicated alignment with adjacent work. B. Use concealed anchorages where possible. Provide brass or lead washers fitted to screws where required to protect metal surfaces and to make a weathertight connection. C. Form closely fitted joints with exposed connections accurately located and secured. D. Provide perimeter reveals and openings of uniform width for sealants and joint fillers, as indicated. E. Install concealed gaskets, flashings, joint fillers, and insulation as louver installation progresses, where weathertight louver joints are required. Comply with Section "Joint Sealants" for sealants applied during louver installation. 3.4 ADJUSTING AND CLEANING A. Clean exposed louver surfaces that are not protected by temporary covering, to remove fingerprints and soil during construction period. Do not let soil accumulate during construction period. B. Before final inspection, clean exposed surfaces with water and a mild soap or detergent not harmful to finishes. Thoroughly rinse surfaces and dry. C. Restore louvers damaged during installation and construction so no evidence remains of corrective work. If results of restoration are unsuccessful, as determined by Architect, remove damaged units and replace with new units. 1. Touch up minor abrasions in finishes with air-dried coating that matches color and gloss of, and is compatible with, factory-applied finish coating. END OF SECTION FIXED LOUVERS
