Window and Door Hardware – Product Performance

In 2019 the Window & Glass Association adopted two Industry Codes of Practice applicable to hardware used on residential windows and doors. These Codes were created to help customers and consumers select hardware appropriate for New Zealand conditions, by providing surety regarding the structural strength and durability of the products they purchase. The performance requirements have been selected as they affect, not only the longevity of the hardware, but also have an impact on the overall performance of the window systems they form an integral part of.


Routine preventative maintenance in accordance with the manufacturer’s instructions is essential to ensure that hardware products achieve their intended useful life.

Certification of hardware

Only products that have been tested and demonstrate compliance with both Codes, meet the industries performance requirements and can be labelled using the Association Tick.
