EgressThe act of leaving an enclosed space. In the window industry, the term refers to the dimensions of the net clear opening of a window or door (the horizontal clear distance, vertical clear distance and the net clear opening are established by local building codes). The reason for establishing minimum egress dimensions is to insure that a person attempting to leave a building in an emergency situation will have room to maneuver. Also, proper egress will allow a firefighter to enter a home while wearing emergency equipment. In 2001, the minimum egress dimensions required by most codes are 20" horizontally, 24" vertically, 5.0 square feet net clear opening for first floor applications and 5.7 square feet net clear opening for second floor applications. Some areas of the country use different dimensions.
