The difference you'll actually feel.
WARMER WINTERS
Less heat escaping, fewer draughts, more even temperatures.
COOLER SUMMERS
Less solar heat gain, less reliance on air-conditioning.
LOWER ENERGY BILLS
Your home holds its temperature more naturally.
REDUCED CONDENSATION
Warmer glass surfaces mean less moisture build-up.
QUIETER INSIDE
Double glazing dampens outside noise significantly.
CODE COMPLIANT
Meets all R-Value requirements across all six NZ climate zones.
WHY GLASS MATTERS
It's not just a window — it's your home's thermal barrier.
The right glazing keeps warmth in during winter, stops your home from overheating in summer, and makes a real difference to your energy bills. It also reduces condensation and dampens outside noise.
​
Modern high-performance glass means you can have large, light-filled spaces and uninterrupted views without sacrificing comfort. Big glazed spans, sliding doors, open-plan living — all of it, without the cold.
​
Low-E glass is now required in all new builds under the NZ Building Code (Clause H1). If you're renovating, upgrading your glazing is one of the smartest moves you can make.
HOW IT WORKS
The Building Blocks of Great Glazing
DOUBLE GLAZING
Two panes of glass with an insulating gap between them. Double glazing significantly reduces heat loss, cuts UV light, and dampens outside noise — the foundation of any thermally efficient home.
LOW-E GLASS
A virtually invisible coating that reflects heat back where you want it — inside in winter, outside in summer. Required in all new builds, and one of the most effective upgrades you can make.
THERMAL SPACER
Holds the two panes apart and seals in the gas fill. A quality warm-edge spacer reduces heat transfer at the edges of the unit — one of the most common weak points in standard double glazing.
GAS FILL
Argon gas fills the space between the panes, insulating far better than air. Paired with a thermal spacer, it meaningfully reduces heat loss in winter and heat gain in summer.
HOW IT WORKS
What Low-E Glass Does
RETAINS HEAT IN WINTER
Low-E reflects warm air back into your home instead of letting it escape through the glass. Less energy, more comfort. Reduces heat loss by nearly 60% more than standard double glazing.*
BLOCKS EXCESSIVE HEAT IN SUMMER
Lets natural light through, but reflects the sun's heat back out. Less heat coming in means less reliance on air-conditioning. Blocks excessive heat by 34% more than standard double glazing.*
FILTERS UV TO PROTECT YOUR HOME
UV causes furnishings, flooring, and fabrics to fade over time. Low-E filters out a significant portion of UV — protecting what's inside your home, not just the temperature.
