SYSTEM DESCRIPTION

Aluminum entrances and storefront system includes tubular aluminum sections with supplementary internal support framing, shop fabricated, factory pre-finished, vision glass, glass infill, related flashings, anchorage and attachment devices.

PERFORMANCE REQUIREMENTS

Design and size components to withstand dead and live loads caused by positive and negative wind pressure acting normal to plane of wall as calculated in accordance with Southern Building code and as measured in accordance with ANSI/ASTM E330.

Limit mullion deflection to flexure limit of glass 3/4 inch (19 mm); with full recovery of glazing materials.

System to accommodate, without damage to components or deterioration of seals, movement within system, movement between system and peripheral construction, dynamic loading and release of loads, deflection of structural support framing.

Limit air leakage through assembly to 0.06 cfm/min/sq ft (0.0003 cu m/s/sq m) of wall area, measured at a reference differential pressure across assembly of 1.57 psf (75 Pa) as measured in accordance with ANSI/ASTM E283.

Vapor Seal with Interior Atmospheric Pressure of 1 inch (25 mm) sp, 72 degrees F (22 degrees C), 40 Percent RH: No failure.

Maintain continuous air and vapor barrier throughout assembly, primarily in line with inside pane of glass and heel bead of glazing compound.

System to provide for expansion and contraction within system components caused by a cycling temperature range of 170 degrees F (95 degrees C) over a 12 hour period without causing detrimental affect to system components.

Drain water entering joints, condensation occurring in glazing channels, or migrating moisture occurring within system, to the exterior by a weep drainage network.
