iCalculation Notes
- • Area calculated as (Width × Height) / 144 for normal analysis
- • For Impact Shutter Analysis: (Height × Height/3) / 144
- • Maximum area for C&C method is 700 ft²
?Zone Selection Guide
- • Zone 5: Openings near building corners (within distance 'a')
- • Zone 4: Openings along the midspan of the wall
