The tilt & turn window is only supplied with one handle making it a more usable and a more easily understood operation than the two or three handle operation available on the market.
Window tilts in at the top for a ventilation position or turns on the side for a larger open area. These can be supplied with a child restrictor. These windows are more easily compliant with fire escape and cleaning regulations. Can be supplied as a single or multiple sash window.
On tall windows and windows located high up or behind worktops the handle can be positioned off centre and nearer the bottom to allow easier access
