Draft Designation: DR AS 2047This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee BD-021, Doors and Windows, to supersede, AS 2047—1999, Windows in buildings. After allowing sufficient time for adjustment (nominally 12months from publication), the superseded document will be withdrawn.
This Standard incorporates Amendment No. 1 (February 2016) and Amendment No. 2 (June 2017). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.
After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian Standard rather than an Australian/New Zealand Standard.
The objective of this Standard is to provide window designers and manufacturers with a generic requirement for windows in buildings, setting out the performance requirements and specifications in the design and manufacture of all windows, regardless of materials.
This edition differs from the previous edition as follows:
(a) Hinged, pivot and bi-fold doors have been added to the scope of the Standard.
(b) Wind pressures for housing, including cyclonic regions and corner conditions, have been updated to ensure alignment with AS 4055, Wind loads for housing.
(c) The deflection/span ratio for housing and residential buildings has been changed to align with the new lower serviceability limit state wind pressures.
(d) Additional guidance is given for the extrapolation of test results to larger size windows and the substitution of structural members and components.
(e) Updated requirements for windows made from unplasticized PVC (uPVC).
(f) The guide to wind pressures (Appendix A) has been revised to ensure alignment with AS 1170.2.
(g) Appendix B (Environmental considerations) has been included to ensure alignment with current Standards.
In this Standard, statements expressed in mandatory terms in notes to tables and figures are deemed to be an integral part of the Standard.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance.
Originated in part as part of SAA Int. 318-1951. Final editions AS2147-1996 and AS 2147.2-1996. AS 2047.1-1996 and AS 2047.2-1996 revised, amalgamated and redesignated AS 2047-1999. Second edition 2014. Reissued incorporating Amendment No. 1 (February 2016). Reissued incorporating Amendment No. 2 (June 2017).
This Standard specifies requirements, materials, construction, installation and glazing for external—
(a) windows;
(b) sliding and swinging glazed doors, including French and bi-fold doors;
(c) adjustable louvres;
(d) shopfronts; and
(e) window walls with one-piece framing elements.
NOTE: Window walls do not include curtain walls using stacked or vertically spliced framing systems, manufactured from any material and installed in external walls of all classes of buildings.
Throughout this Standard, the term ‘window(s)’ means window of any type, including louvre(s) and glazed door(s).
NOTES:
1: The window ratings or classifications differ from previous glass and window Standards due to the more accurate evaluation of the effect of wind conditions. They are based on either AS 1170.2, or the specific wind loading code developed for housing, AS 4055.
2: For information on wind loads applicable to windows covered by this Standard, see Appendix A.
3: Prefabricated bay windows that incorporate sloped glass are classified as windows in external walls.
4: For the performance specifications of building facades, see AS/NZS 4284. Conformance to the requirements of AS/NZS 4284 will be deemed to satisfy the requirements of this Standard, provided the windows have been tested to AS 4420.1 (operating force test).
5: The following are not covered by this Standard but should be checked with the National Construction Code (NCC) for compliance requirements:
(a) Internal doors.
(b) Revolving glazed doors.
(c) Fixed louvres.
(d) Skylights and roof lights and windows in other than the vertical plane.
(e) Windows in greenhouses and agricultural buildings.
(f) Frameless sliding and swinging doors.
(g) Windows constructed on site and architectural one-off windows, which are not design tested.
(h) Second-hand windows, re-used windows or recycled windows.
(i) Heritage windows for heritage buildings, as defined by the relevant State or Territory authority.
