Good Repair Guide: Aluminium windows

Aluminium windows have been available in New Zealand since the late 1950s but were not frequently installed in houses until the early 1970s. Today, almost all window joinery is aluminium framed. Although considered to be maintenance free, all aluminium joinery requires cleaning, and in some circumstances, other care may be required, such as lubrication of hardware. Unless it has been well maintained, early aluminium joinery may now require replacement or removal and refurbishment. 

This guide covers the replacement of aluminium windows that are installed into walls with:

• direct-fixed weatherboard and flat sheet claddings
• brick veneer.
