Aluminium Retrofit Double Glazing
Upgrade Your Existing Aluminium Windows for a Warmer, Quieter, More Comfortable Home
If your home has older single-glazed aluminium windows, retrofitting them with modern double glazing is one of the most effective ways to improve comfort — without replacing your entire window frames. Aluminium retrofit double glazing allows you to keep your existing joinery while upgrading only the glass system, giving you better insulation, less noise, reduced condensation, and improved year-round comfort.
We upgrade aluminium windows across Tauranga and the wider Bay of Plenty.
Why Choose Aluminium Retrofit?
Retrofitting your aluminium windows is the perfect solution when your existing frames are still in good condition. It offers excellent performance improvements at a lower cost than full replacement joinery.
Benefits of aluminium retrofit include:
-
A warmer home in winter
-
Less overheating and glare in summer
-
Reduced outside noise
-
Lower energy use
-
Minimal disruption during install
-
Most affordable upgrade option for aluminium homes
-
No structural work required
-
Clean, modern look retained
Most 1980s–2020s homes are ideal candidates for aluminium retrofit double glazing.
How Aluminium Retrofit Works

Which SuperTherm™ glass option best fits your home
Every job is completed with precise sealing, new gaskets where required, and detailed workmanship to ensure long-lasting performance.
More Affordable Than Full Replacement Joinery
One of the biggest advantages of aluminium retrofit is cost.
Because we reuse your existing joinery, you avoid:
-
New aluminium frame costs
-
Rebuilding openings
-
External cladding work
-
Interior finishing
-
High-labour installation
This makes aluminium retrofit the most budget-friendly double glazing solution for modern homes.
If your frames are damaged, corroded, or you want a brand-new look, we also provide full replacement aluminium windows and doors.
Aluminium Retrofit vs Full Replacement: What’s Right for Your Home?
Aluminium retrofit is ideal when your existing frames are in good condition and you want a cost-effective upgrade that improves the comfort of your home. Retrofit keeps the joinery, reduces waste, avoids major construction work, and delivers excellent insulation and noise reduction.
Full replacement is recommended when:
-
Your existing frames are damaged or corroded
-
Windows no longer open, close, or lock properly
-
You want a new window style or configuration
-
You’re renovating and updating the home’s look
-
You want new colours or upgraded thermal performance
If you’re unsure, our team can assess your frames during a free measure and quote. We’ll talk you through both options so you can choose the solution that suits your home, budget, and long-term plans.
