What is the Purpose of an Egress Window?

Egress windows are not a specific style of window. Rather, an egress window is defined by meeting or exceeding code requirements, particularly,  specific minimum measurements.  While standards for egress windows may vary by county or city in the Dallas/Fort Worth Metroplex, all dwellings must have escape windows. The most important feature is that any adult can easily operate the window and quickly exit the building. Likewise, first responders must be able to gain access to the structure from the outside, taking their equipment into account.

You have several choices in window styles when considering a new egress window. Remember, code requirements and size are the determining factors. The important thing to consider is the ease and accessibility of escape during an emergency. You’ll also want to find windows that are energy efficient and aesthetically pleasing.

Casement Egress windows are typically used for basement installations because their hinged sashes allow them to swing inward or outward. 

Single and double-hung windows are popular and open either upward or downward.

Sliding windows also make excellent egress windows by their nature.
