This innovative window style is designed to operate in three distinct ways:

• Tilt it and turn it upwards for some fresh air without having to unlock the window.
• Turn it to the centre to open up like a side hung window.
• Turn it all the way down to completely close and lock the unit in place.

This makes it ideal for the South African climate in that, as it opens inwards it can be left open in a tilt position at night without compromising security.
