Windows have the ability to make your basement appear more pleasing and offer added safety. Large basement windows, sometimes known as "egress windows," from Pella of Eau Claire let more light into underground rooms than the older, smaller, rectangular windows that are added above ground. They also provide a way out if there's an emergency. Pella® egress windows are available as casement, sliding or double-hung windows.
The main distinction between basement, or egress, windows and standard windows is that basement windows have to be big enough for an average-sized person to escape through in order to meet safety requirements outlined in building codes. You can pick from properly sized casement, sliding or double-hung windows when you add basement windows. Be sure you fully understand local building codes before you purchase basement windows.
