What is double glazing?

Double glazed windows are those that use two panes of glass, rather than one. The two panes are positioned with a void in between that is filled with a layer of insulating Argon gas. The gap in between the panes varies; here at Ecostar, we install a 20mm gap, which delivers superior thermal and noise reduction qualities compared to others on the market.

How does double glazing work?

Glass is a great conductor of heat, meaning traditional single pane windows let a lot of heat into and out of your home. When Argon gas is used between the two panes of glass, it reduces heat and cold transfer. At Ecostar, we combine double glazed glass with uPVC window frames; these frames don’t conduct heat and cold like aluminium and timber, thereby complementing the energy efficiency of double glazing. Combined with insulated pads behind the architraves, our double glazed window units are a complete solution and unlike anything else on the market.

So what does double glazing actually do?

Double glazing does two main things: it increases the energy efficiency of your home, and it also reduces the effect of outside noise.

During winter, double glazed windows keep the heat in; in summer, they keep the heat out. For homeowners, this means you can turn down the heater in winter and reduce your use of air conditioning in summer… saving you money on your electricity and gas bills! Improving the energy efficiency of your home also prolongs the lifespan of heating and cooling appliances, as they don’t need to work as hard.

The additional pane of glass and the void in between also acts as an additional noise barrier, reducing the transfer of sound far better than a single pane of glass. Perfect for buildings in noisy areas!

What are uPVC windows?

Commonly referred to as vinyl windows, uPVC windows are an ‘unplasticised’ form of PVC. Although relatively new to Australian shores, these sturdy window and door frames have long been popular in Europe and America – and for good reason. There is also extensive research completed by the CSIRO, which determined the lifespan to be 70 years with no clear ending as yet.

uPVC window and door frames complement the energy efficiency and noise reduction properties of our double glazed glass window panes. They feature similar thermal properties to timber, and don’t contract or expand like aluminium – helping to maintain the desired temperature of your home whilst also reducing the effect of outside noise.

uPVC windows are incredibly durable and can withstand temperature extremes – from Melbourne’s freezing winters to burning summers – without corroding, peeling, chipping or flaking like timber windows. In short, this means that Ecostar windows are low maintenance; no need to re-paint those weathered timber windows every couple of years! Furthermore, Ecostar is the only company using uPVC frames that are certified UV stabilised.

    Ringwood North, Melbourne

    Stephanie and Daniel Dong’s large Ringwood North home is stunning, but the property’s existing timber, single glazed window frames were rotting and very draughty, reducing the thermal efficiency of their home. Permanently cold in winter and unbearably hot in summer The Dongs engaged Ecostar to install double glazed windows and double glazed doors and enjoyed an instant reduction in their energy bills, and an instant improvement in the temperature within their home, whatever the weather. “We would recommend Ecostar to anyone,” said Stephanie.
