Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br /> <br />STRUCTURAL-SEALANT-GLAZED CURTAIN WALLS <br /> 08 44 23 - 5 <br /> <br /> <br />2. Deflection Parallel to Glazing Plane: Limited to L/360 of clear span or 1/8 <br />inch, whichever is less. <br />a. Operable Units: Provide a minimum 1/16-inch clearance between <br />framing members and operable units. <br />E. Structural: Test according to ASTM E 330 as follows: <br />1. When tested at positive and negative wind-load design pressures, assemblies <br />do not evidence deflection exceeding specified limits. <br />2. When tested at 150 percent of positive and negative wind-load design <br />pressures, assemblies, including anchorage, do not evidence material failures, <br />structural distress, or permanent deformation of main framing members <br />exceeding 0.2 percent of span. <br />3. Test Durations: As required by design wind velocity, but not less than 10 <br />seconds. <br />F. Air Infiltration: Test according to ASTM E 283 for infiltration as follows: <br />1. Fixed Framing and Glass Area: <br />a. Maximum air leakage of 0.06 cfm/sq. ft. at a static-air-pressure <br />differential of 6.24 lbf/sq. ft. <br />G. Water Penetration under Static Pressure: Test according to ASTM E 331 as follows: <br />1. No evidence of water penetration through fixed glazing and framing areas <br />when tested according to a minimum static-air-pressure differential of 20 <br />percent of positive wind-load design pressure, but not less than 12 lbf/sq. ft. <br />H. Energy Performance: Certify and label energy performance according to NFRC as <br />follows: <br />1. Thermal Transmittance (U-factor): Fixed glazing and framing areas shall have <br />U-factor of not more than 0.45 Btu/sq. ft. x h x deg F as determined <br />according to NFRC 100. <br />2. Solar Heat Gain Coefficient: Fixed glazing and framing areas shall have a <br />solar heat gain coefficient of no greater than 0.35 as determined according to <br />NFRC 200. <br />3. Condensation Resistance: <br />a. Defined as water occurring on 5 percent of interior surface of any one <br />component or water that is not collected and positively drained to <br />exterior through a condensation drainage gutter. <br />b. Prevent condensation under the following conditions: <br />1) outdoor ambient temperature of 22.3 deg F at 4.2 mph. <br />2) indoor ambient air temperature of 70 deg F, with 50% relative <br />humidity. <br />I. Hurricane-Resistance Test Performance: <br />1. Comply with the Florida Building Code, 2010 Edition.
