<br />SECTION 10200 - LOUVERS AND VENTS
<br />PART 1 - GENERAL
<br />1.1 SUMMARY
<br />A. This Section includes fixed, extruded -aluminum louvers.
<br />1.2 PERFORMANCE REQUIREMENTS
<br />A. Structural Performance: Provide louvers capable of withstanding the effects of gravity loads and wind loads based on a uniform
<br />pressure of 201bf/sq. ft., acting inward or outward, without permanent deformation of louver components, noise or metal fatigue
<br />caused by louver blade rattle or flutter, or permanent damage to fasteners and anchors.
<br />B. Thermal Movements: Provide louvers that allow for thermal movements resulting from a temperature change (range) of 120 deg F
<br />, ambient; 180 deg F, material surfaces, by preventing buckling, opening of joints, overstressing of components, failure of connec-
<br />tions, and other detrimental effects.
<br />C. Air -Performance, Water -Penetration, and Wind -Driven Rain Ratings: As demonstrated by testing manufacturer's stock units
<br />according to AMCA 500-L.
<br />1.3 SUBMITTALS
<br />A. Product Data: For each type of product indicated.
<br />B. Shop Drawings: Include plans, elevations, sections, details, and attachments to other Work.
<br />1. Verify louver openings by field measurements before fabrication and indicate measurements on Shop Drawings.
<br />C. Samples: For each type of finish upon request of Architect.
<br />D. Product test reports verifying compliance with applicable wind loads by testing methods approved by the authority having jurisdic-
<br />tion..
