Double Glazed Windows and Doors
Double glazed windows use two glass panes that are separated by argon gas to keep your home energy efficient, secure and peaceful. The Argon gas prevents warm air from escaping. The second pane of glass acts as a noise barrier. Our window systems use uPVC which accounts for 80% of the world’s windows. Together, our double glazed uPVC windows offer you exceptional value, thermal efficiency suited for Australian conditions and sustainability.

FAQ
What materials are used in Winplex’s double-glazed windows and doors?
Winplex uses uPVC (unplasticised polyvinyl chloride) for its window and door frames. This material is highly durable, resistant to warping, cracking, and splitting, rot, rust and unlike timber, requires minimal maintenance. The uPVC colours are tropically rated and tested in the harshest environments outperforming powder coating. Furthermore, uPVC offers superior thermal efficiency compared to aluminium or steel frames.
How does Winplex ensure the quality of its double-glazed products?
Winplex is a member of the Australian Glass and Window Association (AGWA) and manufactures its products locally in Australia, adhering to strict Australian quality standards. All double-glazed windows and doors come with a 10-year guarantee, ensuring long-term performance, durability, and customer satisfaction.
What customisation options does Winplex provide for its windows and doors?
Winplex offers a wide range of styles, colours, and finishes to suit different architectural designs and personal preferences. All of our products are custom made allowing homeowners to select products that complement their home’s aesthetic while benefiting from the numerous advantages of uPVC double glazing.
How does Winplex’s installation process work?
Winplex provides a free measurement and quote service to assess your specific needs. Their expert installation team ensures a precise fit, maximising the performance and longevity of your double-glazed windows and doors.
Are Winplex’s double-glazed windows and doors environmentally friendly?
Yes. Winplex’s products are designed to improve energy efficiency, reducing the need for excessive heating and cooling. This lowers energy consumption, cuts down on carbon emissions, and helps create a more sustainable home.
How effective are Winplex’s double-glazed windows and doors at reducing noise?
Winplex’s standard double-glazed windows and doors significantly reduce external noise by over 70%, creating a soundproof barrier with two panes of glass and an insulating air gap. This makes them ideal for homes near busy roads, airports, or other noisy areas, providing a quieter and more peaceful indoor environment.
How do Winplex’s double-glazed windows and doors improve heating and cooling efficiency?
Winplex’s windows and doors help maintain a stable indoor temperature by reducing heat loss in winter and heat gain in summer. The superior insulation minimises temperature fluctuations, leading to lower energy bills and a more comfortable home all year round.
Why uPVC instead of Timber, Aluminium or Steel?
Unlike timber, aluminium and steel, our uPVC frames do not rot, rust, corrode or fade and are made from recycled material requiring no ongoing maintenance. Furthermore uPVC windows and doors feature multipoint locking systems for improved security and which are paired with multiple gasket seals to stop dust and drafts when closed and are not prone to condensation.
