Aluminium Double Hung Windows Sydney from Vista Windows

Double Hung Windows have the virtue of being a non-projecting window, safeguarding pedestrians on walkways.

These windows have a host of user friendly features. Finger grips are set into the top and bottom sashes for convenient operation, while low maintenance spring balances permit effortless opening and closing.

The active sashes are protected with specially designed cam handles available in either locking or non-locking form. Both are smooth to operate and ensure maximum protection.

The double hung window allows easy cleaning of the window exterior. The two independently moving sashes bypass to permit cleaning from the inside. As an additional feature, the double hung window has been created so that flyscreens can be readily and conveniently fitted.
