Glass Options



Glazing choices are important options to consider. Glass can enhance the way your home looks and feels, but it also adds to the warmth and thermal efficiency of your home.

It's a good idea to work through your options to find the right glass for you home. With options to reduce UV, minimise heat loss, and increase year-round comfort, your decisions can have a significant impact on the performance of your glazing.

Some factors to consider and discuss with your manufacturer and the orientation and shading of your home, the climate and noise around where you live. 

There are a variety of performance glass options to suit most requirements. Here is a quick overview of the most popular options to consider.

Double Glazing

Double glazing offers year-round thermal advantages. Benefits include significant reduction in UV light and good retention of internal heat. As a bons, it also dampens sound.

Low-E

Low-E (the 'e' stands for emissivity) glass is a virtually invisible coating incorporated into your double glazing improving the level of insulation in your home. The Low-E coating is applied to the inside surface of the exterior glass pane, protecting it from the elements. 

Thermal Spacers

A thermal spacer reduces heat transfer through the glass edge and improves the seal that is key to genuine double glazing. A thermal spacer holds the two glass panes of your double glazed windows and doors apart and created a seal to hold in the gas fill. This keeps warm and cold areas separated, reducing heat loss around the outside of your glazing. 

Gas Fill

Inert gases such as argon and krypton can be used as an insulator in double glazing to create an additional barrier to heat loss and heat absorption, improving thermal performance. The efficiency of a gas fill is enhanced when paired with a thermal spacer.

Performance Glass

Thermal performance is becoming increasingly important to many homeowners. You can optimise the thermal efficiency of your home by choosing a Performance Glass option to suit most requirements. Low E (the ‘e’ stands for emissivity) glass enhances the insulation value for a modest premium. Further wins can be had by using Argon gas in your double glazing. 

Argon creates an additional barrier to heat loss and heat absorption, achieving good thermal performance gains.An additional option to consider is a thermal spacer in your double glazing which prevents the transfer of hot and cold temperatures between the two pieces of glass.For superior thermal performance combine high performance glass options with ThermalHEART Technology.

Within the general category of double glazing, there are plenty of options to further boost your home’s thermal efficiency by choosing Performance Glass.

Safety glass

Warmth is one thing, but safety is key. All window systems come with glass that complies with NZS 4223, the glazing standard cited in the New Zealand Building Code.

What does Low-E do?

Retains heat - LOW-E reflects the warm air in the home back into the house rather than escaping through the glass. This reduced the energy needed to keep the home warm in cooler months.

Blocks excessive heat - LOW-E lets the sun's visible light pass through but reflects the 'sunheat' back out again. With less heat entering your home, there's less need for air conditioning to keep it cool.

Reduces fading - Low-E helps protect furnishings in the home from fading by reducing the amount of UV light that enters through the glass.
