Retrofitting IGUs
Double glazing, or Insulating Glass Units (IGUs), are increasingly used in New Zealand to improve insulation. This has created a demand to upgrade existing houses.

Double glazing, or Insulating Glass Units (IGUs), are increasingly used in New Zealand to improve insulation. This has created a demand to upgrade existing houses.
Installing windows can be tricky, but there’s plenty you can do to make it easier.
Recent changes to NZS 3604:2011 Timber-framed buildings and NZS 4211:2008 Specification for performance of windows has created an inconsistency between wind zones in these standards.
Water penetration in and around windows and doors can cause significant damage. Following a few easy steps helps manage this risk and protect the vulnerable timber frame. We look at the E2/AS1 option.
Recent changes to E2/AS1 mean that the construction sequence for openings in walls with direct-fix claddings must now be done differently.
This is the second article in a series looking at the thermal performance of residential window systems. The focus this time is solar control glazing and WERS (Window Efficiency Rating Scheme).
E2/AS1 and WANZ WIS offer two different solutions to window head flashing details with bevelback weatherboard cladding installed over a drained and ventilated cavity. What are the differences?
It may seem too much bother, but adding that extra layer of defence around your windows early on, means less chance of having to fix leaks further down the track.
Why is it that windows fixed with claddings over a drained cavity don’t need a sill flashing, while direct-fixed claddings do?
The Window Association of New Zealand has developed an Alternative Solution to the details in E2/AS1. Known as the WANZ WIS details, we look at how it works and what to watch out for.
