AS 2047, 2nd, 2014 – Windows and external glazed doors in buildings
AS 2047 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.
