Double glazing
Two panes with a sealed gap between them — the baseline upgrade for a warmer, quieter home, and right for most NZ houses.
Why uPVC?
Double or triple glazing — and what actually makes the difference.
The glass does as much work as the frame. Here’s how double and triple glazing compare, and what Low-E, argon and warm-edge spacers really do.
How many panes
Double does the job for most homes. Triple is for the extremes.
Triple glazing
Three panes for the highest insulation. Worth it in the coldest, most exposed sites; often more than most homes need.
The details that count
Three small things that change how a window performs.
Low-E glass
A near-invisible coating that reflects heat back into the room instead of letting it escape.
Argon fill
An inert gas in the sealed gap that insulates better than ordinary air.
Warm-edge spacer
An insulating spacer around the glass edge that keeps the inner pane warmer and helps manage condensation.
The right glazing
You choose the glazing to suit your home.
Which way a room faces, how exposed it is, the road outside, your budget — they all change what the right glazing is. So rather than fit the same unit everywhere, we work out what each room needs and explain why, with you as the final decision maker, so you can make an informed decision and get the result you're actually after.

Frequently asked questions
Do I need double or triple glazing in New Zealand?
Double glazing suits most NZ homes and makes a clear difference to warmth and quiet. Triple glazing is worth considering for the coldest, most exposed sites — we’ll advise honestly rather than over-spec.
What does Low-E glass actually do?
It carries a microscopically thin coating that reflects heat back into the room, so you keep more warmth in without losing daylight.
Is argon fill worth it?
Argon insulates better than air for a small added cost, so it’s usually a sensible inclusion for a warmer result.
Will better glazing stop condensation?
It helps manage it — warm-edge spacers and better glazing keep the inner glass warmer, which reduces streaming. Ventilation and heating still play a part.
