Operable Window Technologies supply and install high-level window opening mechanisms, from simple manual shaft & lever to electric and the more discreet chain drives. We have considerable experience and many successful installations particularly in education, community, aged care, commercial & residential sectors.

Other sectors in which we work include churches, hospitals & recreation facilities, including those with a high level of technology requiring full integration with building management systems.
Any windows, which are too high for you to comfortably and safely open and close whilst standing on the floor need gearing. Generally, any window with its lower edge at 1800 mm AFL or above requires some window control system.

Our experience and expertise enable us to work closely with our clients to determine the best solution that meets their operational & aesthetic requirements within budget and within their time frames.



Business is built on relationships and that is a strength of the OWT team. We value our clients, and their clients and strive to provide the best service.


With our intelligent solutions and knowledgeable team, we will find the perfect product to suit your needs.


We are always adapting to the technological changes within the construction industry, to streamline our business and the effectiveness of project completion.
