Tilt and turn windows are the natural choice for a smart modern style with secure ventilation. They allow natural light to flood in whilst providing ample ventilation that can be adjusted to suit your needs. They open from both the top and the side.
One twist of the handle is all you need to open the window slightly for light ventilation. For more, turn the handle again so that the window swings inwards on its side hinges. This is ideal for safely cleaning the windows, as well as providing a suitable fire escape route.
