Hinges are fitted as standard on our casement windows.
These may be released by pressing the buttons within the hinge. A top-opening window will have a button to press on either side of the window. Side-opening windows will have a button at the bottom only.
Spring hook and peg restrictors
These are often fitted to fire-escape windows and released by pushing the hook to the side and away from the peg.
This can be unlocked using an Allen key and opened by pressing the button while opening the window.
Fire-escape and easy-clean hinges
These are fitted to selected windows allowing them to open fully. To operate the easy-clean facility, press buttons both top and bottom and slide the window along. To close the window, press the buttons and pull the window to the closed position.
