Why Double Glazing Isn’t Just for Winter: The Secret to Staying Cool This Summer

When most homeowners think of double glazing, they picture warm, cozy homes in winter. But modern glazing technology has evolved. The right glass can keep your home cooler, brighter, and more energy-efficient through summer too.

If you live in Tauranga or the Bay of Plenty, you already know how intense our sunshine can get. Standard single or double glazing allows solar heat to pour in, turning your living spaces into ovens. That’s where SuperTherm™ Cool double glazing makes all the difference.

Why Homes Overheat in Summer in Tauranga, Bay of Plenty

New Zealand homes are often built for warmth, not for solar control. Standard glass allows up to 80% of the sun’s radiant heat to pass through. Once trapped indoors, that heat quickly raises room temperatures, particularly in north- and west-facing rooms.

When that happens, air conditioners work overtime. This drives up your power bills. Glare becomes a problem, and UV rays begin to fade furniture, flooring, and curtains.

💡 Tip: If your living area feels hotter inside than outside, or you’re constantly drawing the blinds, your glass is likely the problem, not the sunshine.

How SuperTherm™ Cool Double Glazing Works

SuperTherm™ Cool is an advanced Low-E (low emissivity) double glazing system engineered for New Zealand’s unique climate. Unlike standard glazing, it reflects excess solar heat before it enters your home while still letting in plenty of natural daylight.

The secret lies in its microscopic Low-E coating, which bounces infrared and UV rays away from your windows. That means:

• Cooler interiors on hot summer days

• Bright rooms without harsh glare

• Lower air conditioning costs

• Protection from fading and UV damage

  
  

This technology delivers year-round balance - cooler in summer, warmer in winter, and always energy-efficient.
