Windows are able to make your basement more aesthetically pleasing and boost safety. Large basement windows, sometimes referred to as "egress windows," from Pella of Rochester are created to allow more light into underground areas than the older, smaller, rectangular windows that are put above ground. They also offer a way out in case of an emergency.
The main differentiator between basement, or egress, windows and standard windows is that basement windows have to be made for an average-sized person to get out in order to meet safety requirements set up in building codes. You can select from appropriately sized casement, sliding or double-hung windows when you install basement windows. Make sure you fully understand local building codes prior to purchasing basement windows.
