1.2 PERFORMANCE REQUIREMENTS
A. General: Provide steel fire-rated glazed curtain-wall systems, including anchorage, capable of withstanding, without failure, the effects of the following:
1.Structural loads.
2.Thermal movements.
3.Movements of supporting structure indicated on Drawings including, but not limited to, story drift, twist, column shortening, long-term creep, and deflection from uniformly distributed and concentrated live loads.
Specify dimensional tolerances for support system and adjacent construction in other Sections of this Project's Specifications.
4.Dimensional tolerances of building frame and other adjacent construction.
5.Failure includes the following:
a. Deflection exceeding specified limits.
b. Thermal stresses transferred to building structure.
c. Framing members transferring stresses, including those caused by thermal and structural movements, to glazing.
d. Noise or vibration created by wind and thermal and structural movements.
e. Loosening or weakening of fasteners, attachments, and other components.
f. Sealant failure.
B. System Description:
1.Steel fire-rated glazed curtain wall system, outside glazed pressure plate, cover cap format.
2.Face Widths Available:
a. 1 3/4-inch.
b. 2 3/8-inch wide.
3.Water Drainage:
a. System is vertically weeped. No joint plugs or weep holes at horizontal mullions. Horizontal gaskets are notched and received by vertical gaskets.
C. Structural Loads:
1.Uniform Wind Load: ASTM E 330; Static air design load of 40 psf applied in positive and negative direction; no deflection in excess of L/175 of span of any framing member at design load.
2.At structural test load equal to 1.5 times specified design load, no glass breakage or permanent set in the framing members in excess of 0.2% of their clear spans shall occur.
Delete two subparagraphs below if not applicable. See Evaluations.
3.Seismic Loads: [As indicated on Drawings] <Insert specific loads>.
4.Periodic Maintenance-Equipment Loads: [As indicated on Drawings] <Insert specific loads>.
D. Air Infiltration: ASTM E 283; Air infiltration rate shall not exceed 0.06 cfm/ft2 at a static air pressure differential of 6.24 psf.
E. Water Resistance, (static): ASTM E 331; No leakage at a static air pressure differential of 30 psf as defined in AAMA 501.
F. Water Resistance, (dynamic): AAMA 501.1; No leakage at an air pressure differential of 30 psf as defined in AAMA 501.
G. Thermal Movements: Provide steel fire-rated glazed curtain-wall systems that allow for thermal movements resulting from the following maximum change (range) in ambient and surface temperatures. Base engineering calculation on surface temperatures of materials due to both solar heat gain and nighttime-sky heat loss.
Differential values below (for aluminum in particular) are suitable for most of the U.S. Revise to suit local conditions and metal color and finish.
1.Temperature Change (Range): 120 deg F (67 deg C), ambient; 180 deg F (100 deg C), material surfaces.

1.6 PROJECT CONDITIONS
A. Field Measurements: Verify actual locations of structural supports for steel fire-rated glazed curtain-wall systems by field measurements before fabrication and indicate measurements on Shop Drawings.
Delete below if not allowed.
1.Established Dimensions: Where field measurements cannot be made without delaying the Work, establish dimensions and proceed with fabricating steel fire-rated glazed curtain-wall systems without field measurements. Coordinate construction to ensure that actual dimensions correspond to established dimensions.
