month I would like to discuss bedroom egress windows. As
most of us are aware, any sleeping room requires secondary
exit (egress) directly to the exterior. Some bedrooms are
equipped with an exterior door, which of course would qualify
as an exit.
homes do not have this luxury and provide egress via a window.
Any exit window requires a sill not more than 44-inches
from the interior finished floor. The openable portion must
have 5.7 square feet of opening to allow escape or fire
personnel entry. The 2003 IRC has an exception for windows
with direct grade access, they may have 5 square feet of
windows are also required to have minimum opening dimensions.
The minimum open space width is 20-inches, the minimum height
is 24 inches. See the table below for the correlating width
or height to meet the minimum size of 5.7 square feet.
course many older homes (the egress requirement has been
in the Codes for about 35 years) may not have proper size
and/or placed windows. In this instance I use modern standards
as my guide and recommend to the clients to consider upgrading
the window size for increased safety.
tip: When the windows are casement style (side hinged) open
the window and be sure it does not strike the fascia board
or other obstruction to prevent full opening of the sash.
I have found this condition several times, particularly
Check Building, published by the Taunton Press, has tables
for determining proper opening for egress windows with both
the 5.7 and 5.0 square feet requirements.
Here is a sample of the information available.
this sample will take you to the Kaplan website to view
all Code Check books.
