Another valuable function of a basement window is as a means of entrance or exit from the house should situation prove necessary. Because of this use there are certain specification that must be met when selecting basement windows. For one, basement windows are not like the other windows in your home, so do not be fooled into thinking you can just get the same windows for every space in your home. Basement windows are specially designed for installation in masonry foundation walls. Although they are, generally speaking, relatively small in size compared to most of the vast array of windows available, it is important to select basement windows that meet the egress standards of local codes when the windows will be installed in a finished basement. So what are these standards or size, etc.? According to the International Residential Code, an egress window must be at least 24 in. wide and 20 in. high with a net clear opening of at least 5.7 sq. ft. to allow occupants to escape in an emergency or to allow a fully outfitted firefighter to enter from the outside. While this may seem like a rather large space for a basement window, should your house ever catch fire, and a firefighter need enter through a basement window, you will be grateful for such regulations.
