Windows can make your basement more visually pleasing and offer added safety. Large basement windows, sometimes referred to as "egress windows," from Pella of Syracuse are made to allow more light into underground rooms than the older, smaller, rectangular windows that are added above ground. They also give you an escape in case of an emergency.
The primary differentiator between basement, or egress, windows and standard windows is that basement windows have to be big enough for an average-sized person to get out in order to meet safety requirements set up in building codes. You can choose from appropriately sized casement, sliding or double-hung windows when you add basement windows. Make certain that you completely understand local building codes before your purchase of basement windows.
