Double Glazed Casement Windows
A casement window is a window that is attached to its frame by one or more hinges. Casement windows are hinged at the side, and open outwards like a door. They are used singly or in pairs inside a common frame, in which case they are hinged on the outside.
When the window is hinged at the top, it is called an awning windows.
When you have two sashes that meet in the middle, inside the same frame, and swing outwards, that’s known as a French window.
They are opened with a crank, lever or cam handle, which is placed around hand height or at the bottom and serves as a window lock. A crank, stay, or friction hinge is necessary when the window opens outward, to hold the window in position despite wind.
Casement windows are also excellent for taking advantage of natural ventilation, especially when it’s hot. They can be hinged to open outward and angled in order to direct breezes into the home. The ability to open the windows to get natural breeze ventilation, and the insulating properties of double glazing, make this window very versatile.
To enjoy the greatest control over the balance between view and privacy, and the amount of light coming into your room, consider ordering your new windows with internal venetian blinds.
