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.
Flat skylight
A flat skylight is a window that lies horizonally in a roof opening.
IFC 2x3 note
For IFC2x3 there are no PredefinedType enumerators for a window and a flat skylight is simply treated as a window. Do not designate a PredefinedType.
