Aluminium Insert Double Glazing
A Smart Upgrade for Bay of Plenty Homes
Not every home needs full window replacement to achieve better comfort.
If your existing aluminium joinery is still in good condition, aluminium insert double glazing offers a practical, cost-effective way to upgrade performance without removing your existing frames.
It is one of the most efficient ways to improve warmth, reduce condensation, and make your home more comfortable year-round, especially across Tauranga and the wider Bay of Plenty.
What Are Aluminium Inserts?
Aluminium inserts involve installing a new, slimline aluminium double glazed frame inside your existing timber window frame.
Your original window frame stays in place, while the new insert sits neatly within it, fitted with high-performance double glazing.
This allows you to upgrade to modern double glazing without the cost and disruption of full frame replacement.
When Are Aluminium Inserts the Right Option?
Aluminium inserts work best when your current frames are structurally sound but underperforming.
They are a strong option if:
-
Your existing timber joinery is still in good condition
-
You want a more modern, low-maintenance alternative to timber
-
You are looking for a more cost-effective upgrade than full timber retrofit
-
You want to reduce condensation and improve overall comfort
-
You prefer a quicker, less invasive installation process
If your frames are worn, damaged, or poorly sealed, we may recommend a different approach. The goal is always the right solution for your home, not a one-size-fits-all answer.
Designed for Bay of Plenty Conditions
Homes across Tauranga, Mount Maunganui, and Papamoa are exposed to coastal air, strong sun, and changing temperatures throughout the year. Aluminium inserts allow us to improve performance without needing to replace your existing frames.
With our SuperTherm™ range, the glass can be tailored to suit how each space performs:
-
SuperTherm™ Warm for colder or shaded areas
-
SuperTherm™ Cool for managing heat and glare in sun-exposed rooms
-
SuperTherm™ Protect for added noise reduction and UV control
-
SuperTherm™ Customised for a more tailored, window-by-window solution
This approach ensures you are not over- or under-specifying the glass across your home.
How Does It Compare to Other Options?
Aluminium Inserts vs Timber Retrofit Double Glazing
-
Inserts add a new internal aluminium frame
-
Retrofit replaces the glass within your existing timber frame
-
Inserts can offer improved sealing and consistency depending on the condition of the original joinery
-
Inserts offer a more modern finish with low long-term maintenance
-
Retrofit retains the original character and aesthetic of your home
Aluminium Inserts vs Full Replacement
-
Inserts retain your existing outer frames
-
Full replacement removes everything and starts fresh
-
Inserts are more cost-effective, while replacement offers maximum performance and flexibility
We often recommend a combination approach, using inserts in some areas and full replacement in others where it makes more sense.
