Whether you have a bay window or a casement unit, your windows have to be code-compliant, meeting standards in place to keep you safe. The key aspects every code-compliant window has to address include:
Energy Conservation – Windows have to suit energy codes, meeting U-factor and solar heat gain coefficient ratings ideal for a certain location.
Safety Glazing – If a window is situated in one of the seven locations identified as hazardous by the IRC, it has to be safely glazed with security film or tempered glass.
Fall Protection – An operable window with a sill height below 24 inches above the floor is required to be no more than six feet above the grate outside the window to protect children from severe injury after falling through double-hung windows with low sills.
Emergency Escape and Rescue – In 2015, the IRC stated that window sills cannot be more than 44 inches high from the floor and windows must open no less than 24 inches high or 20 inches wide.
How Code Compliance Affects Your Window Choices
Complying with code requirements can limit your window choices because window styles and materials can affect what you can get. For example, vinyl windows have thicker frames so using them results in smaller openings. Unfortunately, this can be problematic where egress requirements have to be met. As a compromise, a window style that has a bigger opening by design can be chosen, like swapping sliding windows for casements. However, this can also be at odds with homeowner associations, for example, that call for matching windows in their neighborhood.
