ENTRANCES & STOREFRONTS Section 08410 15-1207 PART 2 -PRODUCTS 2.01 PERFORMANCE REQUIREMENTS A. Wind loads: Provide framing system; include anchorage, capable of withstanding wind load design pressures of (25) lbs./sq. ft. inward and (25) lbs./sq. ft. outward. The design wind load shall be based on 85 MPH exposure "C" per Article 1.06 A. B. Air Infiltration: The test specimen shall be tested in accordance with ASTM E 283. Air infiltration rate shall not exceed 0.06 cfm/ft2 at a static air pressure differential of 6.24 psf. C. Water Resistance: The test specimen shall be tested in accordance with ASTM E 331. There shall be no leakage at a minimum static air pressure differential of 8 psf as defined in AAMA 501. D. Uniform Load: A static air design load of 20 psf shall be applied in the positive and negative direction in accordance with ASTM E 330. There shall be no deflection in excess of L/175 of the span of any framing member. At a structural test load equal to 1.5 times the specified design load, no glass breakage or permanent set in the framing members in excess of 0.2% of their clear spans shall occur. E. Thermal Transmittance (U -factor): When tested to AAMA Specification 1503, the thermal transmittance (U -factor) shall not be more than: 1. Glass to Exterior — 0.47 (low -e). 2. Glass to Center — 0.44 (low -e). 3. Glass to Interior — 0.41 (low -e). F. Condensation Resistance (CRF): When tested to AAMA Specification 1503, the condensation resistance factor shall not be less than: 1. Glass to Exterior — 70frame and 69glass (low -e). 2. Glass to Center — 62 name and 68glass (low -e). 3. Glass to Interior — 56 fame and 67 g,ass (low -e). G. Entrance Performance Requirements: 1. Air Infiltration: For single action offset pivot or butt hung entrances in the closed and locked position, the test specimen shall be tested in accordance with ASTM E 283 at a pressure differential of 6.24 psf for single doors and 1.567 psf for pairs of doors. A single 3'0" x 7'0" entrance door and frame shall not exceed 0.50 cfm per linear foot of perimeter crack. A pair of 6'0" x 7'0" entrance doors and frame shall not exceed 1.0 cfm per linear foot of perimeter crack. 2. Structural: Corner strength shall be tested per Kawneer's dual moment load test procedure and certified by an independent testing laboratory to ensure weld compliance and corner integrity. 2.02 MANUFACTURER A. Acceptable Manufacturers: Kawneer Company, Inc. of Norcross, GA 3
