Why Ecostar uPVC double glazed windows and doors are better than aluminium and timber windows and doors

Ecostar uPVC double glazed windows and doors are an energy-efficient, sustainable solution to Victoria’s hot summers and cold winters.

Reduce your energy bills with windows and doors that exceed Australian Window Energy Rating Scheme standards.

Ecostar double glazing is durable. Painted timber window and doorframes split, crack, fade and peel.

Where aluminium window and doorframes expand and contract, conducting heat and cold into your home, Ecostar double glazed windows warm your home in winter and cool your home in summer.

Ecostar double glazed windows and doors eliminate outside noise by up to 90%.

Ecostar double glazed windows and doors are UK police-preferred ‘Secured by Design’ quality accredited to keep your home safe and secure.

Ecostar doesn’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
  • "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
  • "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."

Case Studies

  • Customer Name: Stephanie & Daniel Dong

    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

    Toorak, Melbourne

    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.

  • Customer Name: Angelina and Tim

    Box Hill North, Melbourne

    Situated just 40 meters from Melbourne’s busy Eastern Freeway, Angelina and Tim’s home was cold in winter, hot in summer, and traffic noise was seriously impacting their quality of life. We replaced the couple’s single-glazed windows with uPVC double glazed awning windows and they’ve seen a 38 per cent decrease in their gas bill as a result of their home’s improved energy efficiency.

  • Customer Name: Alan and Jan Hume

    South Yarra, Melbourne

    South Yarra penthouse dwellers Alan and Jan Hume turned to Ecostar in the face of rising energy costs, mounting window and door maintenance and intrusive traffic noise. Their new Ecostar uPVC double glazed windows and doors saved them approximately 50 per cent on their energy bills.
