Casement windows and doors are hinged at the side and opens either on the left or right side. These are fully sealed, when closed and let abundant natural sunlight and fresh air inside your home when left open.
Top hung/ Awning Windows
Hinged at the top of the window unit, the sash pane beneath swings outward from the bottom and can be positioned so that it is fully opened or almost closed, as you prefer. Water can run off an angled sash with ease, but they still allow air to move around without any danger of your home becoming wet.
Top hung windows can be combined with larger fixed windows at the bottom which allows for a good view to be maintained at eye level as well as providing a reasonable amount of air flow at the upper level of the window, where most of the hot air in a home sits.
