Windows have the ability to make your basement more visually pleasing and offer added safety. Large basement windows, sometimes referred to as "egress windows," from Pella of Boston are made to allow more light into underground spaces than the older, smaller, rectangular windows that are put above ground. They also offer a way out in case of an emergency.
The biggest distinction between basement, or egress, windows and standard windows is that basement windows have to be large enough for an average-sized person to get out in order to meet safety requirements set up in building codes. You can choose from correctly sized casement, sliding or double-hung windows when you install basement windows. Be sure you totally understand local building codes before you purchase basement windows.
