5.9.3. Other Fenestration Assemblies
(See Note A-5.9.3.)
5.9.3.1. General
  1. For the purpose of this Subsection, the term "other fenestration assemblies" refers to curtain walls, window walls, storefronts and glazed architectural structures.
    (See Note A-5.9.3.1.(1).)
5.9.3.2. Structural and Environmental Loads
  1. Other fenestration assemblies and their components shall be designed and constructed in accordance with Article 5.1.4.1.
    (See Note A-5.9.3.2.(1).)
5.9.3.3. Heat Transfer
  1. Other fenestration assemblies and their components shall meet the heat transfer performance requirements stated in Section 5.3.
    (See Note A-5.9.3.3.(1).)
  2. Other fenestration assemblies using metal framing that separate interior conditioned space from interior unconditioned space or exterior space shall incorporate a thermal break to minimize condensation.
5.9.3.4. Air Leakage
  1. Other fenestration assemblies and their components shall be designed and constructed in accordance with Section 5.4.
  2. Except as provided in Sentence (3), other fenestration assemblies and their components shall have an air leakage characteristic, measured at an air pressure difference of 75 Pa, when tested in accordance with ASTM E 283, "Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen," that is not greater than
    1. 0.2 L/(s·m2) for fixed portions, including any opaque portions, and
    2. 1.5 L/(s·m2) for operable portions.
      (See Note A-5.9.3.4.(2).)
  3. The following systems need not comply with Sentence (2):
    1. interior windows and interior doors that do not serve as environmental separators,
    2. vehicular access doors (garage doors),
    3. storm windows and storm doors,
    4. commercial entrance systems,
    5. revolving doors,
    6. smoke and relief air vents,
    7. site-built door systems, and
    8. commercial steel doors.
      (See Note A-5.9.3.4.(3).)
5.9.3.5. Water Penetration
  1. Other fenestration assemblies and their components shall be designed and constructed in accordance with Section 5.6.
  2. Except as provided in Sentence (4), other fenestration assemblies and their components not covered in Article 5.9.2.2. shall resist water penetration when tested in accordance with
    1. ASTM E 331, "Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference," or
    2. ASTM E 547, "Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Cyclic Static Air Pressure Difference."
      (See Note A-5.9.3.5.(2).)
  3. Tests referred to in Sentence (2) shall be carried out at the driving rain wind pressure as calculated in accordance with CSA A440S1, "Canadian Supplement to AAMA/WDMA/CSA 101/I.S.2/A440-11, NAFS - North American Fenestration Standard/Specification for Windows, Doors, and Skylights."
    (See Note A-5.9.3.5.(3).)
  4. The following systems need not comply with Sentence (2):
    1. interior windows and interior doors,
    2. vehicular access doors (garage doors),
    3. storm windows and storm doors,
    4. commercial entrance systems,
    5. revolving doors,
    6. smoke and relief air vents,
    7. site-built door systems, and
    8. commercial steel doors.
      (See Note A-5.9.3.5.(4).)
