Helping Australians create homes that are warmer in winter,cooler in summer and cheaper to run

ecoGlaze^® Retrofit Double Glazing works by trapping a layer of still-air between your existing windows and the acrylic panel. This layer of air greatly reduces the heat and cold transfer through your glass window. The acrylic panel is secured in place by beautifully made timber or aluminium mouldings held firmly to the window frame with invisible magnets.

Generally speaking, the ecoGlaze® Retrofit Double Glazing System can be easily applied to all timber windows.  This is dependent on the window frame having enough room for the ecoGlaze® system and sufficient insulating air pocket. 

Most residential aluminium-framed windows do not allow enough space for the ecoGlaze system to fit. However, many homes (particularly apartments) are fitted with commercial aluminium window frames, which are often the perfect size.

Refer to our specialist ecoGlaze website to check whether your windows are suitable for ecoGlaze.

ecoGlaze^® is a suitable treatment for timber framed glazing, doors included. It can be applied to French doors; sliding doors; hinged doors; doors with colonial bars; or doors with lead lighting.

No, the ecoGlaze^® Retrofit Double Glazing System does not alter the operation of your windows or doors. You will be able to open them normally.

The largest ecoGlaze^® panel that can be safely installed is 3000mm x 2000mm.

No. One of the greatest benefits of ecoGlaze is that it blends seamlessly with your existing windows. This also makes ecoGlaze perfect for Heritage listed buildings seeking a greater level of energy efficiency.

This is one of the most impressive features of ecoGlaze®.

The ecoGlaze® Retrofit Double Glazing System is supplied in either raw timber (Tasmanian Oak) or White Powder Coated Aluminium.   The raw timber mouldings are ready to be stained and finished for you to match your existing window frames. If you are having your ecoGlaze professional installed, custom paint colours can also be arranged for an additional fee.

ecoGlaze^® is primarily a thermal product, that means it is designed to improve the comfort of your home in summer and winter.  All forms of secondary glazing will reduce street noise to some extent, however, while it provides some acoustic benefit, its major focus is to vastly improve the thermal performance of the glazing in a way that is aesthetically beautiful.

Neither ecoGlaze^® nor any other form of retrofit double glazing will totally eliminate external noise from your home and should not be viewed as a complete sound-proofing solution. Sound travels around building elements and so it can travel around an acoustically effective window or door.

Any noise abatement should be undertaken in a holistic manner and would usually include thorough draught proofing as well as treatments to the walls, floors and ceilings. Often in apartments the glazing is the major source of noise infiltration and, therefore ecoGlaze^® would provide significant acoustic benefit.

Yes, it certainly will. ecoGlaze® will reduce the heat loss by more than 50%, making a huge difference to the comfort of your home.  This will significantly save you on your winter heating bill because you will need to use your heater much less.  HOWEVER, your home is an ecosystem, so you need to ensure that you have treated the biggest areas of leakage in your home first.  Check out I don’t know where to start to give you a good indication of the sequence of home retrofit.

Even traditional double glazing solutions cannot solve the problem of direct summer sun striking the glass.
Providing there is no direct sunlight striking your windows, the ecoGlaze^® Retrofit Double Glazing System is highly effective in making sure that the summer heat stays outside. ecoGlaze^® will reduce the heat transfer by up to 50%.  However, if there is direct summer sun striking the glass, then external shading is the appropriate solution.

Brand new double glazed windows are much more expensive than secondary glazing. There is also a considerable amount of effort involved in selecting, arranging, installing, plaster repair, painting and cleaning up afterward.

With replacement windows, the old heavy windows also need to be removed and properly disposed of.  Tradesmen need to install the new windows carefully and the architraves and plaster around each window replaced or repaired. Finally, the painters will need to repaint walls and/or architraves to match your existing paintwork.  It can be challenging to co-ordinate multiple tradespeople in a timely manner when trying to get your home back to normal.

Also, we often we hear that people are disappointed to find that their brand new double glazing does not allow the adequate still air space to deliver the comfort they paid for.

No structural changes are required to install ecoGlaze.  Your home is left clean and tidy with seamless secondary glazing that provides perfect still air space.

There are a number of glazing companies that provide this service.  Please be mindful that your original window frames were designed for a single pane of glass and are weighted to allow them to open and close normally.  So there are two issues with replacing the glass:

1. Adding an IGU to single glazed windows will make them very heavy. The additional weight is often too heavy to allow the windows to self-support in an open position. Doors that have been treated this way often experience strain on the hinges or tracks which can cause problems in the future.
2. The smaller the gap between layers of glass, the less effective it will be. Because your original frames were designed for a single pane of glass, they were not constructed to accept wider glazing units.  This forces the replacement glazing (IGU) to be very narrow, fitting two layers of glass into a space that was designed for one layer.  This compromises its thermal effectiveness as the gap will allow conduction of heat and cold, which is exactly what you are trying to avoid.

ecoGlaze^® has none of these problems because it weighs much less than glass, allows your windows to open and close normally. Its design provides the best possible still-air space to maximise thermal performance.

It is not necessary for the ecoGlaze^® system to be sealed. ecoGlaze^® creates a still-air space between the existing glass and the added acrylic panel. It is the still-air space that provides the insulative effect in ecoGlaze^® and all other forms of secondary or double glazing.

ecoGlaze^® does not contain Argon or any other chemical element.  Argon filled double glazing is one of the most expensive types of double glazing available. It is important to note that Argon provides virtually no additional benefit unless it is combined with a ‘low e coating’, which requires the glass to be replaced.

Believe it or not, no glazing is vacuum sealed because it would put the two panes of glass under pressure and eventually the two panes would touch. Factory fitted double glazing is hermetically sealed, meaning that no air can enter or escape.
