If your home is too hot in summer or too cool in winter, then SuperTherm^™ double glazing is an excellent solution.

SuperTherm™ is a new generation of glass that is used in superior double glazing. It is noticeably clearer than traditional window glass and has a nanoscopically thin coating on one side, which is undetectable to the human eye. This coating is protected by being sealed inside the double-glazing unit and has special properties, acting as a filter to let the right light in.

You may have heard of “Low e” glass.  Low e glass (or “low emissivity glass”) responds to different types of light, letting daylight light pass through and blocking particular wavelengths of heat energy. SuperTherm™ is a highly advanced low-emissivity glass.

To understand how SuperTherm™ works, we need to consider the “electromagnetic spectrum” from the Sun. This spectrum can be more readily thought of as “light”, being the energy radiated by the Sun. It has three distinct parts…

UV (ultraviolet) light
UV is invisible. It is good at killing germs (for example, it is good as part of the cleaning process for clothing on the washing line). However, it not healthy for our skin in excess and can cause significant fading of furnishings in our homes.

VL (visible light)
Visible light is the spectrum of light we see as daylight. It contains the full spectrum of colour and is what brings natural daylight into our homes. This daylight also contains some heat energy and contributes to fading.

IR (infrared)
Infrared is invisible (but we see and feel the effects). It contains lots of heat energy that we feel as radiant heat. Depending on the climate we live in, this heat energy may or may not be wanted.  Infrared also contributes to fading.

In New Zealand homes, we generally want healthy ‘daylighting’ that comes from visible light and much less of the unhealthy UV light, while managing a comfortable level of warmth.

The heat energy generated within your home is at a different wavelength than the heat energy that comes from the Sun. SuperTherm™ is designed to filter this inside heat energy, keeping it in and contributing to insulating your home more effectively. It is a far superior glass for keeping the warmth inside your home.

There are three alternative SuperTherm™ double glazing options, giving you greater flexibility to select a solution tailored to your needs.

Talk with a double glazing expert about the right SuperTherm™ double glazing option to use in each part of your home to achieve superior all-round home comfort.

lets daylight and warmth in, and keeps it in

SuperTherm Warm™ double glazing is designed to maximise daylight and free warmth from the Sun, whilst providing outstanding thermal insulation.

The glass used in SuperTherm is a neutral, lower iron glass, designed to let in lots of daylight. Its nanoscopic coating is specially designed to let the radiant heat from the Sun pass through, yet stop the heat produced within your home (for example, from a fireplace or electric heating, from electrical appliances and from people). SuperTherm Warm™‘s heat-loss-stopping-power is remarkable. Compared with single glazing, it can reduce heat loss through the double glazing by up to 81%!

SuperTherm Warm™ is designed for homes, or areas in a home, where the owners are seeking to capture as much warmth from the Sun (particularly in the cooler months) and keep the warmth in.

lets daylight in while keeping the radiant heat out, and insulates superbly

SuperTherm Cool™ double glazing has been developed for homes where the Sun’s radiant heat causes overheating. Its nanoscopic coating is designed to block this heat and reduce glare, while still letting through a large proportion of daylight. While its heat rejection properties don’t eliminate the need for summer cooling ventilation, SuperTherm Cool™ does something remarkable. It has heat rejection performance that is better than tinted glass commonly used all around New Zealand, yet without compromising daylighting.  Its insulation performance is also superior. SuperTherm Cool reduces heat loss through glass by up to 83%, compared with single glazing.

SuperTherm Cool™ double glazing is designed for homes, or areas in a home, where owners are seeking to reduce the radiant heat from the Sun in summer, yet require excellent insulation in the cooler months.

SuperTherm Protect™ double glazing combines the superior performance of SuperTherm Cool™ to provide increased home comfort and protection in three areas.

First, it provides impressive noise insulation, which compared with 3mm single glazing, equates to a perceived noise reduction of up to 63%.

Second, it has far superior protection of furnishings from fading.  This comes from its virtual elimination of UV, together with stopping the majority of the Sun’s radiant heat.

Third, the inside glass pane has superior strength and safety properties that provides a greater level of home security.  In the event of a natural disaster, the glass is more likely to hold in place, protecting the occupants of the home.

SuperTherm Protect™ is designed for New Zealand homes that require a higher standard of all-around comfort and protection.

now you can really enjoy your view

While its all-round performance is impressive, SuperTherm™ double glazing does this without compromising the clarity of the glass. Views through the glass will look more natural, closer to what it would look like with no glass, while a whole lot more comfortable.

world-class double glazing

Glass is a major contributor to heat loss in homes around the world.  Significant research and development continues world-wide to develop products that provide a higher level of home comfort through their insulating properties.  The performance of SuperTherm™ in its ability to let light in and provide superior insulation is outstanding. We believe it is a world-class solution for New Zealand homes.
