Janex Fully Reversible Windows offer a robust and low maintenance window solution.  Sometimes referred to as Topswing, Canopy or H-Type windows these have been the Scandinavian window of choice for decades due to their outstanding weather performance.

A perfectly balanced outward opening window with market leading hardware, the Janex Fully Reversible Window has integral restrictors to provide both child safety and allow safe cleaning and maintenance from within the building.

Handles are positioned at the bottom of the window and ideally suited for easy access and operation.  The “night-vent” position allows for increased ventilation with the window remaining securely locked.
