SuperTherm™ Double Glazing: The Goldilocks Standard of Comfort for Kiwi Homes
Every Kiwi homeowner knows the struggle of a house that never feels quite right – sweltering in summer, chilly in winter, and expensive to keep comfortable. What we’re really searching for is that “just right” feeling: balanced, healthy comfort all year round.
At RetroGlaze®, we call this the Goldilocks Standard of comfort. It’s the benchmark we use to measure every home we transform, and it was the driving force behind developing our SuperTherm™ double glazing range. Created by RetroGlaze®, SuperTherm™ is designed specifically for New Zealand’s unique climate.
Why Standard Double Glazing Isn’t Enough in New Zealand
Standard double glazing can help reduce winter heat loss, but it rarely solves the bigger picture. In New Zealand’s strong sunshine, homes are still vulnerable to overheating, UV damage, and high energy use, leaving living spaces feeling more like greenhouses than comfortable retreats..
Auckland’s overheated townhouses are a clear example: highly insulated, yet unprotected from solar gain, they trap the heat inside and leave families sweltering through summer with no escape.
The truth is most glazing systems on the market are designed with cold climates in mind. They simply aren’t equipped to handle the intensity of Kiwi sun. That’s why RetroGlaze® created the SuperTherm™ range – Cool, Protect, and Warm – engineered to deliver the Goldilocks Standard of comfort in every season.
SuperTherm™ Warm – Winter Insulation That Works
For south-facing rooms or colder regions, SuperTherm™ Warm is engineered to keep heat where it belongs – inside your home. By reflecting warmth from heaters
and fireplaces back into the room, it reduces heat loss by up to 81% compared with single glazing.
That means warmer winter nights, improved energy efficiency, and a home that feels drier, healthier, and more comfortable through the colder months.
SuperTherm™ Cool – Smarter Summer Comfort
For north- and west-facing rooms that bear the brunt of the afternoon sun, SuperTherm™ Cool dramatically reduces solar heat gain without sacrificing natural
light. Unlike tinted glass, it keeps interiors bright and clear while cutting harsh glare.
The result is cooler living spaces, reduced reliance on fans or air conditioning, and lower power bills, a smarter, more energy-efficient way to enjoy summer comfort in New Zealand homes.
SuperTherm™ Protect – UV and Noise Control for Kiwi Homes
This makes Protect the ideal choice for busy urban areas, coastal properties, or anywhere Kiwi homeowners want quieter living, sun protection, and long-lasting interior comfort.
The result is cooler living spaces, reduced reliance on fans or air conditioning, and lower power bills, a smarter, more energy-efficient way to enjoy summer comfort in New Zealand homes.
The Goldilocks Comfort Plan – Tailored Double Glazing Solutions
No two homes are the same, which is why there’s no one-size-fits-all glazing solution. At RetroGlaze®, we design tailored glazing solutions that combine different SuperTherm™ products across your home to achieve balance in every room.
What makes this truly unique is our thermal reporting system. Your local RetroGlaze® partner provides a detailed thermal report and recommends precise
adjustments to pane thickness, airspace, and laminate composition. These refinements ensure your glazing isn’t just installed but that it’s fully optimised for your
home’s comfort.
- SuperTherm™ Cool in sun-soaked living areas to reduce overheating
- SuperTherm™ Protect in bedrooms for UV protection and quieter nights
- SuperTherm™ Warm in shaded or south-facing rooms for winter comfort
The outcome is a whole-home solution that delivers the Goldilocks Standard of comfort: cool in summer, warm in winter, quiet, protected, and energy efficient all year round.
With RetroGlaze®, you’re not just upgrading your windows – you’re future- proofing your home. Backed by Kiwi innovation, advanced thermal reporting, local expertise, and trusted installation, SuperTherm™ makes it easy to enjoy that “just right” feeling every day.
