This category refers to windows that are either on the basement or first floor. Not every egress window needs to meet the 5.7 square foot requirement set out by the IRC. When the window is on the basement or first floor level, the building code only requires a 5-square-foot clear opening for egress windows. Our below-grade egress windows are the perfect option for looking for a quick and easy way to get a window that meets the 5-square-foot egress code requirement. Remember: it is ultimately your responsibility to confirm with local building inspectors to determine which size you need in your region and for your given situation. We have 2 window sizes that meet this square footage requirement. Available in 2 sizes: 30"w x 36"h (5.26 sqft clear opening) 36"w x 30"h (5.30 sqft clear opening) The egress window with hinges side hung is in-swinging and hinged along the side, meaning that it operates in much the same way that a door does.
