Egress Window
Egress windows allow natural light to flood into the basement, adding value to the home and possibly increasing the home's square footage. It is most commonly utilized in a basement bedroom. To build a bedroom in your basement and expand your living space, regulations require an egress window for a fire escape. According to the International Residential Code, basement windows must have the following:
-
The bottom of the egress window opening cannot exceed 44 inches from the finished floor
-
The clear opening of at least 5.7 square feet
-
The opening width of at least 20 inches
-
Opening height of at least 24 inches
Additional requirements in the Chicago area vary; it is recommended to check with the local building department in the local City Hall to learn these requirements.
Important features for installing the egress window
Insulation
The opening in the wall should be a little bigger than the size of the window to utilize insulation foam to maintain energy efficiency and prevent heat or cool air to escape or the outside weather to seep in.
Proper Installation and Waterproofing
Proper installation and waterproofing of geh egress window well serves to keep the basement dry. The well needs to be secured in multiple places to prevent movement. Specific materials seal the window well externally and internally, preventing seepage and water leaks.
Protection from Water Leaks and Seepage
To provide adequate protection a drain has to connect to either the exterior or interior system. It'll guarantee against water leaks and seepage.
