Verify that Section titles referenced in this Section are correct for this Project's Specifications; Section titles may have changed.

PART 1 - GENERAL

1.1  SUMMARY

  2. Exterior and vestibule aluminum-framed storefronts where glazing is retained mechanically with gaskets on four sides. Designated as Type 1.
  3. Conventionally glazed aluminum curtain walls installed as unit-and mullion systems. Designated as Type2.
  4. Aluminum-framed skylights where glass glazing is retained by field-installed pressure caps on four sides. Designated as Type 3.
  5. Exterior aluminum doors and frames.

1.2  PERFORMANCE REQUIREMENTS

  1. General: Provide aluminum-framed systems, including anchorage, capable of withstanding, without failure, the effects of the following:
  2. Structural loads.
  3. Thermal movements.
  4. Movements of supporting structure indicated on Drawings including, but not limited to, story drift 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.

  1. Dimensional tolerances of building frame and other adjacent construction.
  2. Failure includes the following:
  3. Deflection exceeding specified limits.
  4. Thermal stresses transferred to building structure.
  5. Framing members transferring stresses, including those caused by thermal and structural movements, to glazing.
  6. Noise or vibration created by wind and thermal and structural movements.
  7. Loosening or weakening of fasteners, attachments, and other components.
  8. Failure of operating units to function properly.
  9. Wind Loads: Provide entrance and storefront systems, including anchorage, capable of withstanding wind-load design pressures calculated according to requirements of authorities having jurisdiction or the American Society of Civil Engineers' ASCE7, "Minimum Design Loads for Buildings and Other Structures," 6.4.2, "Analytical Procedure," whichever are more stringent.
  10. Deflection of Framing Members Normal to Wall Plane: Limited to 1/175 of clear span for spans up to 13 feet 6 inches and to 1/240 of clear span plus 1/4 inch for spans greater than 13 feet 6 inches or an amount that restricts edge deflection of individual glazing lites to 3/4 inch, whichever is less.

Before retaining testing requirements in remainder of this Article, verify that manufacturers have tested assemblies according to test method indicated and can meet criteria specified.

  1. Structural-Test Performance: Systems tested according to ASTME330 as follows:
  2. When tested at positive and negative wind-load design pressures, systems do not evidence deflection exceeding specified limits.
  3. When tested at 150 percent of positive and negative wind-load design pressures, systems, including anchorage, do not evidence material failures, structural distress, and permanent deformation of main framing members exceeding 0.2 percent of span.
  4. Test Durations: As required by design wind velocity but not less than 10 seconds.

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): Systems accommodate 120 degF, ambient; 180 degF, material surfaces.

ASTME283 requires using a static-air-pressure difference of 1.57 lbf/sq. ft. (75 Pa), unless otherwise indicated, which is equivalent to a 25-mph (40-km/h) wind. Static-air-pressure difference of 6.24 lbf/sq. ft. (300 Pa) is equivalent to a 50-mph (80-km/h) wind.

  1. Air Infiltration: Maximum air leakage through fixed glazing and framing areas of systems of 0.06 cfm/sq. ft. of fixed wall area when tested according to ASTME283 at a minimum static-air-pressure difference of 6.24lbf/sq.ft..

For water-penetration test, static-air-pressure difference of 20 percent of wind-load design pressure provides satisfactory performance in most parts of the U.S. Locations where high winds and heavy rains frequently occur simultaneously require higher test-pressure differences. Lower test-pressure differences are acceptable for some locations. Revise paragraph below to suit Project.

  1. Water Resistance: Systems do not evidence water penetration through fixed glazing and framing areas when tested according to ASTME331 at a minimum static-air-pressure difference of 8 psf. As defined in AAMA 501.
