Bay windows project beyond the building envelope, creating unique wind load conditions. The projection catches wind differently than flush windows, and the angled panels experience combined forces that require structural engineering for both the glazing and support system.
Typical maximum projections range from 18-24 inches for residential bay windows in HVHZ, depending on configuration. Box bays are typically limited to 18 inches, while angled bays can extend to 24 inches with proper support.
Bay windows can be supported by steel cable systems from above, knee braces or corbels below, cantilever framing from the floor system, or a combination. The support must resist both gravity loads (window weight, roof) and lateral wind forces.
Yes, bay windows can include operable casement or double-hung units in the side panels. The center panel is typically fixed for strength. All operable units must have NOA approval and appropriate hardware for the design pressure.
