Standards New Zealand has published a revised Specification for performance of windows, NZS 4211:2008, to update and replace the 1985 version. This Standard is used for testing windows as they would be supplied ex factory, to the site.
The Standard’s processes and procedures for testing and materials have been significantly updated. The revision clarifies how to apply the Standard, and aligns it with the AS/NZS 1170 series, Structural design actions. The Department of Building and Housing intends to commence its process for referencing this Standard in Compliance Documents for the New Zealand Building Code.
