A window is predominately used to provide natural light and fresh air. It includes constructions with swinging, pivoting, sliding, or revolving panels and fixed panels. A window consists of a lining and one or several panels.
Window
In this instance a window is a standard window usually within a wall opening, as a window panel in a curtain wall, or as a "free standing" window.
IFC 2x3 note
For IFC2x3 there are no PredefinedType enumerators for a window. Do not designate a PredefinedType.
