A casement is a window that is attached to its frame by one or more hinges at the side. They are used alone or in pairs within a common frame, in which case they are hinged on the outside.
A jalousie window is composed of parallel glass set in a frame. The glass may be tilted open and shut in unison to control airflow by turning a crank.
Seamless windows involve sheets of super-strong tempered glass that are held in place invisibly. It is stylish and can be used in both the home and office.
