A Tailored Approach to Double Glazing
Not every window needs the same solution, and this recent project in Pyes Pā, Tauranga, is a great example of why.
The homeowners wanted to improve the year-round comfort and functionality of their home, while making the most of their existing spaces.
Rather than taking a one-size-fits-all approach, our team combined three different double glazing solutions: aluminium full replacement, aluminium inserts and timber retrofit, each selected to suit the requirements of different areas of the home.
The result is a comprehensive upgrade that demonstrates how different glazing solutions can work together to create a more comfortable and functional living environment.
The Project: Three Double Glazing Solutions, One Home
For this Pyes Pā home, we combined three double glazing solutions to suit the different windows, spaces and needs of the homeowners.
Aluminium Full Replacement
We replaced selected windows and doors with new aluminium joinery and high-performance SuperTherm™ double glazing. A standout feature was converting an existing bay window into bifold doors, improving indoor-outdoor flow and making the living space more functional.
Aluminium Inserts
For the bedrooms, laundry and bathrooms, we installed aluminium inserts, retaining the existing outer frames while upgrading to new aluminium joinery and SuperTherm™ double glazing.
This provided a more cost-effective alternative to full-frame replacement.
Timber Retrofit Double Glazing
Rather than replacing an existing timber door, we retrofitted it with SuperTherm™ double glazing, retaining its original character while improving thermal performance.
A Tailored Approach
By combining three different solutions, we improved the home's comfort and functionality while retaining suitable existing joinery and keeping costs in mind.
Smart Glass for Everyday Comfort
Alongside selecting the right joinery solutions, we incorporated both SuperTherm™ Cool and SuperTherm™ Warm Low-E double glazing.
These products are designed to address different thermal requirements:
-
SuperTherm™ Warm Low-E: Helps reduce heat loss through windows, improving insulation and comfort during the cooler months.
-
SuperTherm™ Cool Low-E: Helps manage solar heat gain, making it particularly beneficial for areas exposed to strong sunlight.
Using different glazing products within the same home allows us to consider factors such as window orientation, sun exposure and how individual rooms are used.


Why SuperTherm™?
SuperTherm™ Low-E double glazing is a next-generation glass designed to give you better insulation and more natural light. It features a super-thin, invisible coating sealed between two panes of glass, acting like a clever filter that controls heat and light — without darkening your view.
Compared to standard double glazing, SuperTherm™ offers:
-
Nearly double the insulation performance
-
Clearer, brighter glass with less glare
-
Protection from UV damage
-
Improved year-round temperature control
It’s a great option for families looking to make their home more energy-efficient and comfortable without compromising on looks.
The Result: Improved Comfort, Functionality and Indoor-Outdoor Flow
This Pyes Pā project demonstrates that a complete double glazing upgrade doesn't necessarily mean replacing every window in the same way.
By combining aluminium full replacement, aluminium inserts and timber retrofit, we delivered a tailored solution designed around the home's existing joinery and the homeowners' goals.
The conversion of the bay window into bifold doors was a particularly significant transformation, improving access to outdoor spaces and creating greater flexibility for everyday living.
It's a great example of how the right combination of products can improve more than just a home's thermal performance. It can also change how the spaces are enjoyed.
