SECTION 10 71 13 – EXTERIOR SUN CONTROL DEVICES
PART 1 - 	GENERAL
1.1	SUMMARY
A.	Section Includes:
1.	Fixed blade extruded-aluminum exterior mounted louvered sunshades including attachment brackets and trim.
1.2	PERFORMANCE REQUIREMENTS
A.	Design:  Design sunshades, including comprehensive engineering analysis by a qualified engineer, using structural performance requirements and design criteria indicated.
B.	Structural Performance:  Sunshades shall withstand the effects of gravity loads and the following loads and stresses within limits and under conditions indicated without permanent deformation of sunshade components and mounting brackets, or permanent damage to fasteners and anchors.
1.	Wind Loads:  Determine loads based on a uniform pressure of 30 lb./sq. ft. (1435 Pa), acting perpendicular to sunshade surfaces.
C.	Thermal Movements:  Provide sun control system that allows for thermal movements resulting from a maximum change in ambient and surface temperature as indicated without buckling, overstressing of components, failure of connections, or other detrimental effects.
1.	Temperature Range: 120° F (49° C) ambient and 180° F (82° C) at material surfaces.
1.3	SUBMITTALS
A.	Product Data:  For each type of product indicated.
1.	Include technical data demonstrating mounting and fastening methods, material descriptions, construction details, dimensions of assemblies and components, appearance details, and finishes.
B.	Shop Drawings:  For exterior sunshades and accessories.  Include plans, elevations, sections, details, and attachments to other work.  Show frame profiles and blade profiles, angles, and spacing.
C.	Samples:  For each type of metal finish required.
D.	Submittal:  For sunshades indicated to comply with structural performance requirements and design criteria.
PART 2 - 	PRODUCTS
2.1	MATERIALS
A.	Aluminum Extrusions:  ASTM B 221M, Alloy 6063-T5.
B.	Aluminum Sheet:  ASTM B 209M, Alloy 3003 with temper as required for forming.
C.	Fasteners:  Use types and sizes to suit unit installation conditions.
1.	For fastening aluminum, use aluminum or stainless-steel fasteners.
2.2	FABRICATION, GENERAL
A.	Fabricate frames, including outriggers, in dimensions as indicated.  Include allowances for fabrication and installation tolerances, adjoining material tolerances, and thermal movements.
B.	Space the blades as indicated, and the outermost blades within the frame, to create a uniform appearance.
C.	Join frame members to each other and to fixed louver blades with threaded fasteners concealed from view.

1.	Color and Gloss: As selected by Architect from manufacturer's full range.
PART 3 - 	EXECUTION
3.1	INSTALLATION
A.	Locate and mount sunshades level, plumb, and at indicated alignment with adjacent work.
B.	Use fastening and mounting methods in accordance with manufacturer instructions.
C.	Use concealed anchorages where possible, with locations as directed by manufacturer instructions.
D.	Repair damaged finishes so no evidence remains of corrective work.  Return items that cannot be refinished in the field to the factory and refinish entire unit or provide new units.
E.	Protect galvanized and unfinished nonferrous-metal surfaces that will be in contact with concrete, masonry, or dissimilar metals from corrosion and galvanic action by applying a heavy coating of bituminous paint.
