Top Hung Timber Windows

Top hung casement windows are hinged at the top of the frame and open outward from the bottom. They’re operated by a handle that controls a multi-point locking system, and when opened, they create a canopy effect that deflects rain away from the interior whilst allowing fresh air to enter your home.

Side hung casement windows are hinged at the side and open outward like a door, providing maximum ventilation when fully opened. Top hung casement windows are hinged at the top and open outward from the bottom, offering more secure ventilation as they can be left open safely whilst you’re out. Both styles can be combined in the same window frame for versatility.
