Switch to cheaper glazing

Switching to a lower spec system typically means lower thermal performance, higher power bills and increased condensation. That said, there is a move towards the use of cheaper but high spec imported double-glazing units from China which can save thousands.

However, rather than sourcing these direct it’s best to work with a reputable company that knows the manufacturer and will fit the windows themselves, taking responsibility for any problems with sizing, fabrication, New Zealand compliance and the like. Be aware that there will usually be much longer lead times.
