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

Casement windows are side-hung and outward opening. Duo Glass casement windows give improved ventilation into your home when required and the same excellent sealing properties as other casement designs when closed. They are an increasingly popular option for double glazing in Perth, Western Australia.


Sliding windows are a popular choice in Australia due to their space-saving design and simple operation. Duo Glass's sliding windows allow for a variety of installation requirements and do away with the built-up grime that accumulates in the joints and tracks in standard Aluminium sliders.

Double Glazed Awning Windows

Awning-style double glazed windows are top-hung with stainless friction stays. We have options for support arms, restrictors and a range of coloured locking handles to match our profiles. These are an excellent design for acoustic and weatherproofing purposes, and allow ventilation without encroaching on internal space.

Tilt and Turn

Tilt and turn windows are extremely popular in Europe and lend themselves well to multi-storey homes and buildings and high wind loads. Tilt-and-turn uPVC windows are ultra secure, extremely versatile and can offer very large openings while remaining air-tight and easy to operate. Whether opened horizontally for increased cross flow or left vertically ajar for superior ventilation of built-up stuffy air at ceiling level, you'll love showing off the dual action handle and gearing to your friends!

Our profiles are manufactured in Germany specifically for Australian conditions.
