WOOD WINDOWS

This Section uses the term "Architect." Change this term to match that used to identify the design professional as defined in the General and Supplementary Conditions.

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

GENERAL

SUMMARY

This Section includes operable wood-framed windows of the following type:

Adjust list below to suit Project.

Aluminum clad.

DEFINITIONS

Retain abbreviations, definitions, and terms that remain after this Section has been edited.

Performance grade number according to AAMA/WDMA 101/I.S.2/NAFS:

Design pressure number in pounds force per square foot used to determine the structural test pressure and water test pressure.

Structural Test Pressure: For uniform load structural test, is equivalent to 150 percent of the design pressure.

Minimum Test Size: Smallest size permitted for performance class (gateway test size). Products must be tested at minimum test size or at a size larger than minimum test size to comply with requirements for performance class.

PERFORMANCE REQUIREMENTS

Performance class designations according to AAMA/WDMA 101/I.S.2/NAFS is Residential (R).

General: Provide wood windows capable of complying with performance requirements indicated, based on testing manufacturer's windows that are representative of those specified, and that are of test size as indicated in Summary of Work.

Retain paragraph and subparagraphs below if Architect has either delegated design responsibility to Contractor or wants to review structural data as another way to verify windows' compliance with performance requirements or performance designation.

Structural Performance: Provide wood windows capable of withstanding the effects of the following loads based on testing units representative of those indicated that pass AAMA/WDMA 101/I.S.2/NAFS, Uniform Load Structural Test:

Model building codes require windows and other fenestration to be designed and installed, according to ASCE 7, to withstand wind pressure loads for components and cladding. Revise subparagraph below if loads are developed from wind-tunnel tests. Building heights and window locations should be shown on Drawings.

Design Wind Loads: Determine design wind loads applicable to the Project site from basic wind speed indicated in miles per hour at 33 feet above grade, according to ASCE 7, Section 6.5, "Method 2-Analytical Procedure," based on mean roof heights above grade.

Delete four subparagraphs below if information is indicated on Drawings. Other factors that adjust for building height, shape, and other characteristics such as topographic factor, gust effect factor, and enclosure classifications may need to be included. This information should enable contractors to require window manufacturers to determine positive and negative design wind pressure loads.

AAMA/WDMA 101/I.S.2/NAFS makes an exception to requirement in ASTM E 1300 and in GANA's "Glazing Manual" for R, LC, and C class windows that frame systems be sufficiently stiff to limit lateral deflections of glass edges to less than 1/175 of their length. Only AW and HC class windows must pass the Uniform Load Deflection Test. Retaining subparagraph below for windows other than AW and HC classes may require manufacturers to provide a custom window unless calculations or test data recorded during the Uniform Load Structural Test indicate that frame deflections comply with the 1/175 limitation.

Deflection: Design glass framing system to limit lateral deflections of glass edges to less than 1/175 of glass-edge length or 3/4 inch, whichever is less, at design pressure based on testing performed according to AAMA/WDMA 101/I.S.2/NAFS, Uniform Load Deflection Test or structural computations.

Model building codes and ASCE 7 establish criteria for buildings in hurricane-prone locations. Authorities having jurisdiction may accept other test methods and protocols. Verify requirements of authorities having jurisdiction.
