A house is not a home without DuoGlass double-glazed windows.

Casement windows

DuoGlass’ casement windows are side-hung and can be outward or inward opening.

This type of window is one of Perth’s most popular types of double glazed windows in due to it’s simplicity and ease of use. It functions in the exact same way as a standard outward or inward opening window, but massively outperforms standard windows with its superior noise reduction and insulation qualities, which only comes with double glazing, due to our superior uPVC Frame, and Argon Filled Insulated Glass Units (IGU’s).

The casement windows can provide an unrestricted opening angle allowing extra ventilation and fresh air to flow into your into your home when desired. When closed, the combined features of air-tight seals and double glazed technology blocks external air draft and minimises external temperature penetration (i.e. reducing heat and cold penetration through the window, unlike a standard single-paned window).

Sliding windows

DuoGlass’ double glazed sliding windows are a popular choice in Perth due to their space-saving design and simple operation.

It functions in the exact same way as a standard aluminium sliding window, but massively outperforms them with its superior noise reduction and insulation qualities, which only comes with double glazing, due to our superior uPVC Frame, and Argon Filled Insulated Glass Units (IGU’s).

The installation and functioning of the double glazed sliding windows helps drastically reduce the build up of dust and grime that accumulates in the joints and tracks of standard aluminium sliding windows, making them almost maintenance free. You will also not get any bumps or jambs when sliding the window open or shut.

The sliding windows can be opened and locked at any opening amount providing peace of mind knowing you are safe and secure. When closed, the combined features of air-tight seals and double glazed technology blocks external air draft and minimises external temperature penetration (i.e. reducing heat and cold penetration through the window, unlike a standard single-paned window).

Awning windows

DuoGlass’ awning windows are top-hung and can be adjusted to the desired opening width for maximum safety and security. The outward opening design is perfect for weatherproofing purposes and allow ventilation without impacting internal space.


DuoGlass’ double glazed awning windows are a popular top-hung window that opens outward from the base.

It functions in a similar way that a normal awning window works, but massively outperforms standard windows with its superior noise reduction and insulation qualities, which only comes with double glazing, due to our superior uPVC Frame, and Argon Filled Insulated Glass Units (IGU’s).

The windows feature stainless friction stays (which keeps the window open at your desired amount) with options for additional support arms and restrictors (to limit the maximum opening width for safety or security).

There are a big range of coloured locking handles to match our frames, which provides a great look, but also peace of mind with security and safety.

Strengthened awning hardware is fixed within the profile walls into internally integrated steel reinforcing, making awning-style windows an attractive and safe choice for those who like the traditional looks of hopper windows and the airtight performance of our twin compression awning system. All of our awning windows feature a lockable vent position to enable bathrooms and ensuites to remain secure while allowing airflow as required.

When closed, the combined features of air-tight seals and double glazed technology blocks external air draft and minimises external temperature penetration (i.e. reducing heat and cold penetration through the window, unlike a standard single-paned window).

Tilt and turn windows

DuoGlass’ double glazed tilt and turn windows are a popular Perth choice and are particularly beneficial for homes that face strong winds.

Tilt-and-turn double glazed windows are ultra secure, extremely versatile and are very easy to operate. As the name suggests, these windows enable you to open your windows either horizontally, or vertically, to maximise air ventilation and flow. The control of the horizontal or vertical opening is controlled by one easy-to-use handle that has a dual action to open at your desired angle.

When closed, the combined features of air-tight seals and double glazed technology blocks external air draft and minimises external temperature penetration (i.e. reducing heat and cold penetration through the window, unlike a standard single-paned window).

These double glazed windows massively outperform other single glazed windows due to the superior noise reduction and insulation qualities, which only comes with double glazing, due to our superior uPVC Frame, and Argon Filled Insulated Glass Units (IGU’s).

DuoGlass double glazed windows and doors offer a huge range of benefits for both you and your home. These include:

  • Savings on your electricity bills
