Windows are able to make your basement more aesthetically pleasing and offer added safety. Large basement windows, sometimes known as "egress windows," from Pella of Evansville are built to permit more light into underground areas than the older, smaller, rectangular windows that sit above ground. They also offer a way to get out in case of an emergency.
The primary differentiator between basement, or egress, windows and standard windows is that basement windows must be large enough for an average-sized person to make it 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 add basement windows. Make sure you totally understand local building codes prior to purchasing basement windows.
