Choose SuperTherm™ Low-E double glazing.

SuperTherm™ is a new generation of Low-E glass that is used in superior double glazing.  It is clearer than traditional window glass and has a nanoscopically thin coating on one side, which is indetectable to the human eye.  This coating is protected by being sealed inside the double glazing unit.  It 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 wavelengths of light, letting daylight light pass through and blocking particular wavelengths of heat energy and UV.  SuperTherm™ is a highly advanced Low-E glass.

The heat energy generated within your home is at a different wavelength than most of the heat energy that comes from the Sun.  SuperTherm™ Low-E double glazing is designed to reflect this inside heat energy, keeping it inside your home and contributing to insulating your home more effectively.  It is a far superior double glazing for keeping the warmth inside your home.

Compared to Standard double glazing (sometimes referred to as “Classic”), SuperTherm™ double glazing insulates approaching twice as well.  You might call it “double double glazing”.

“Choose SuperTherm™double glazing to maximise heat retention, optimise solar heat, maximise daylight, and minimise UV light.”

SuperTherm Warm™

Lets daylight and warmth in, and keeps it in.

SuperTherm Warm™ double glazing is designed to maximise solar energy in the form of daylight and warmth, while delivering outstanding thermal insulation.

SuperTherm™ is made from a neutral, lower iron glass purposely formulated so it will let in lots of natural daylight.  Its nanoscopic coating is specially designed to allow radiant heat from the Sun to pass through with ease while stopping heat you’ve produced inside your home (e.g., from the fireplace or heater, from electrical appliances and from people).

The superior performance of SuperTherm Warm™ means it can reduce heat loss through the double glazing by up to 81% when compared to single-glazing.

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

SuperTherm Cool™

lets daylight in while managing solar heat, and insulates superbly.

SuperTherm Cool™ double glazing is specially designed for homes where overheating from the Sun’s radiant heat is a problem.  Its nanoscopic coating is designed to allow large amounts of natural daylight to pass through whilst limiting unwanted heat and reducing glare.  For example, it is an excellent solution to use in West-facing windows that have too much solar gain in Summer.

SuperTherm Cool™’s nanoscopic coating is designed to limit the Sun’s heat and reduce glare, while still letting through a large proportion of daylight.   It has heat rejection performance that is better than the dark, tinted glass commonly used all around New Zealand, yet without compromising daylighting.  SuperTherm Cool™ reduces solar heat gain into the home by 66% but keeps a healthy 70% of daylight, brightening up your interior.  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 an excellent solution for homes, or areas in a home, where owners are seeking to reduce the radiant heat from the Sun in summer, and require excellent thermal insulation in the cooler months – to keep the warmth in.

SuperTherm Protect™

provides superior all-round home comfort and protection.

SuperTherm Protect™ combines the superior performance of SuperTherm Cool™ with acoustic laminated glass to provide increased home comfort and security.

SuperTherm Protect™ has excellent fading reduction properties.  It stops 66% of radiant heat from entering your home, reducing the heat damage that contributes to fading and keeping the inside of your home cooler on those hot summer days, and it eliminates 99% of damaging UV light (the main contributor to fading).

SuperTherm Protect™ provides impressive noise insulation performance, with a perceived noise reduction of 63% (compared to 3mm single glazing), helping to reduce the impact of external noise such as cars or the neighbours barking dog!

Further, the internal laminated glass pane has superior strength and safety properties, providing a greater level of home security.   SuperTherm Protect™ is more likely to hold in place when impacted, whether by burglars, cricket balls or extreme weather events, protecting the occupants inside the home.

SuperTherm Protect™ is designed for New Zealand homes, or areas of homes, that require a higher standard of year-round comfort and protection.

Window wisdom.

Low E (or Low Emmisivity) glass is a coated glass where the coating on this glass acts as a filter to let the right solar energy in whilst rejecting the damaging effects of excessive heat and light.  Read more ….

When it comes to improving your home comfort by increasing the insulation performance of your windows, there are many products available in New Zealand to choose from.

Genuine double glazing is a unit that consists of two pieces of glass connected by a hermetically (air-tight and water-tight) sealed spacer and filled with either air or argon gas.  Read more….

Did you know that up to 50% of a home’s heat is lost through windows and doors!?  Single-glazed windows lead to colder homes and a greater likelihood of condensation and moisture.

High-performing, Low E double glazing, such as the RetroGlaze SuperTherm™ range, can keep the cold temperatures at bay giving you a better-insulated home.  Read more…

Sick of having to dry off your window frames through winter?  Do you have beautiful timber joinery, but the constant puddles are starting to cause the timber to deteriorate and rot?

Condensation forms when warm air is cooled to a point where it releases the held moisture vapour which then condenses on the glass forming, what can be, significant amounts of water.  Read more…

It’s cold, wet and noisy outside.It shouldn’t be like that inside too.

But this is the reality of life without double glazing. You might relate:

  • Winter ills have you off work again but you haven't had time to accumulate more leave from work since the last bout of cold and flu.
  • The tint on your windows is so dark, it feels like you live in a cellar, without the wine! Surely there's a way to balance the heat and light?
  • Your favourite couch has faded from a once deep red to a dull pink. How can you prevent furniture fading and still keep that natural light?
  • The neighbours dog sounds like it's trying out for NZ's got talent. There has to be a way to stop the barking, without having to move house.
  • Violent crime seems to be part of life in many local communities today. It's a must that your loved ones be protected indoors.
  • It's freezing cold outside and just as cold inside. Better put on those thermals and pump up the heater before you settle in for the game
