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.
