Double glazing offers homeowners several advantages. A warmer home leads to lower energy bills, reduced condensation and noise and increased property value. Despite a an upfront cost, the long-term returns make it a smart investment.
How much does it cost to double-glaze a house in NZ?
Double-glazing a home can cost anywhere north of $5000, depending on the size of the home, the glass specifications, and the number of windows.
Retrofitting your windows is the most cost-effective way to double-glaze your house if your current frames are in good condition and will not need replacing soon. Complete window replacement, including the frames, can cost more, but the long-term benefits can outweigh the cost in some cases.
If you’re looking to get double glazing installed in your home but can’t afford it, get in contact with us, and we can recommend special grants that people can access. A good example is Westpac is offering a 5-year interest-free loan of up to $50,000 for homeowners to reduce their environmental impact. Double glazing is one of the qualifying factors.
How do I change my windows to double glazing in NZ?
Switching to double glazing is a pretty straightforward process for our team at Duco Group. First, we’ll assess your current windows to determine if retrofitting will be suitable or if you’re looking at window replacements. If it’s the latter, it’s time to consider the material you’d like for your frames, which will impact your total spend. In addition to the frame, we’ll help you select what type of glass you’ll be switching to, with premium options to increase energy efficiency, noise-reduction glass or triple glazing for extra insulation.
When installing, our glass fitter will ensure the panels are fitted and sealed correctly to avoid leaks or drafts. If they complete a window replacement, they’ll remove the entire frame, prep the opening, and install the new frame and double-glazing panels.

- Decreased energy bills—Double glazing your property can improve your home’s energy efficiency by 70%, drastically reducing your monthly energy bills. Not only will you need less heating in winter, but your double glazing will help keep the heat out in summer, reducing energy costs from ACs and fans.

What are the benefits of double glazing?
-
Wind protection: The layer between two-pane glass creates a more airtight barrier to help prevent drafts from wind passing into the house.
-
Thermal insulation: Double glazing reduces heat transfer from the exterior to the interior. The air gap between the two panes acts as an insulator, massively slowing down the movement of hot and cool air.
-
Condensation control: In winter, single-pane windows cause significant condensation problems in homes, but double-glazing can eliminate this issue.
-
Noise reduction: The extra layer of glass mutes outside noise, making for a more peaceful home.
-
Energy bill savings: By reducing the heat transfer between the exterior and interior of your home, you can reduce the need for constant heating or AC and decrease energy costs.
