Windows can make your basement more visually pleasing and improve safety. Large basement windows, sometimes referred to as "egress windows," from Pella of Wilmington are built to allow more light into underground rooms than the older, smaller, rectangular windows that are put above ground. They also provide an escape in case of an emergency.
The main differentiator between basement, or egress, windows and standard windows is that basement windows are required to be large enough for an average-sized person to escape through in order to meet safety requirements set up in building codes. You are able to pick from properly sized casement, sliding or double-hung windows when you install basement windows. Make certain that you fully understand local building codes before your purchase of basement windows.
