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.

Why choose Ecostar uPVC double glazed windows and doors?

Ecostar uPVC double glazed windows and doors are an energy-efficient, sustainable solution to Australia’s harsh climate – in particular Melbourne’s hot summers and cold winters.

The combination of double glazing and uPVC frames mean Ecostar’s windows and doors are the ultimate package for those looking to reduce their energy bills and help out the environment along the way. We all know Melbourne is busier than ever before – whether it’s traffic noise, the local train line or a busy apartment block next door, you’ll appreciate the fact that Ecostar double glazed windows and doors eliminate outside noise by up to 90%.

Of course, if you’ve read double glazed window reviews you’ll be aware that not all double glazing specialists use the same quality of product. Ecostar windows and doors exceed Australian Window Energy Rating Scheme standards, and are UK police-preferred ‘Secured by Design’ quality accredited to keep your home safe and secure. You can also rest assured that Ecostar windows are fitted by experts; we don’t sub-contract. Our company-employed window and door installation team are fully trained, professional and efficient.

What our customers say

  • "To say we were totally pleased with our Ecostar windows and doors is an understatement. Instantly, the traffic noise was a thing of the past and the house was so quiet. Wonderful. And, despite energy costs having really increased over the last few years, our bills were around 40% lower than in the past. We sold our home for $1.2 million and, bearing in mind where we live, we would never have got anywhere near this price if we had not invested in Ecostar Double Glazing."

    Alan and Jan Hume
    South Yarra
  • "I could not be more delighted with such a positive result. We can hardly hear any traffic now, even at peak hours on the freeway. We are sleeping so much better too. In summer the house is noticeably cooler and we use hardly any air conditioning. We can look forward to winter for the first time since we moved in"

    Angelina L
    Box Hill
  • "We had our first five windows and a door replaced with Ecostar double glazing four years ago and loved the results so we saved up to get the rest of our house double glazed and we couldn't be happier. The windows look fantastic, they’re more secure, save us money on energy bills and we’re less bothered by outside noise. Ecostar's service was excellent and their installers did a fantastic job, even taking away the old windows as part of their service."

    Peter and Jill Garbett
    Croydon
  • "From the very first meeting it was clear that Ecostar was very professional. We quickly reached the conclusion that Ecostar products were of very high quality. The windows are looking great and we are very happy. I have just completed the Customer Service Survey and I am pleased to say I gave Ecostar top marks for their sales presentation, their surveyor, the office team and their installers. We will defnitely recommend Ecostar to our family and friends."

    Nick Pattison
    Toorak
  • "Our house now looks fantastic. People walk through the house and cannot believe how much warmer the house has become. The 90% noise reduction has blown me away."

    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.

  • Customer Name: Nick Patterson

    Nick Patterson had done his research and knew he wanted to install uPVC double glazed windows to improve the kerb appeal of his multi-million dollar Toorak home, to improve his property’s thermal efficiency, improve ventilation and reduce noise from the adjacent main road. We were delighted to receive a glowing customer survey response from Mr Patterson after the successful installation of his uPVC windows, and his on-going recommendation to family and friends.
