Windows can make your basement appear more pleasing and improve safety. Large basement windows, sometimes referred to as "egress windows," from Pella of Baltimore are built to allow more light into underground areas than the older, smaller, rectangular windows that are put above ground. They also offer an escape in case of an emergency.
The biggest difference between basement, or egress, windows and standard windows is that basement windows are required to be big enough for an average-sized person to make it out in order to meet safety requirements set up in building codes. You are able to select from appropriately sized casement, sliding or double-hung windows when you put in basement windows. Be sure you fully understand local building codes before your purchase of basement windows.
