What is a bay angle?
Projection Wall Angle. Projection Offset = ( Back Wall Length — Face Wall Length ) ÷ 2 Projection Wall Angle = arctan ( Projection Offset ÷ Projection ) Example with CMC back wall = 8’ - 0’’ face wall = 4’ - 0’’ project ion = 24’’ projection offset = 24’’.

To Calculate a Bay Roof. Select Bay Window Roof from the dropdown list or select the Bay Roof button on the toolbar to calculate a bay roof. The preview window displays a plan view and elevation view of the bay roof that reflect the current bay dimensions.
Projection Wall Angle = arctan ( Common Rafter Run ÷ Projection Offset ) Interior Wall Angle = ( 90° - Projection Wall Angle) + 90° BHRR Bisect Angle = Interior Wall Angle ÷ 2
For existing openings, measure the jamb of a nearby door or window within the same wall. Measure only the face of the existing jamb, inside-casing to inside-casing. Determine "P" dimension (Projection). Viwinco makes 10 degree, 30 degree, and 45 degree bay windows.
