![]() ![]() ![]() For assemblies comprised of more than one unit mulled together or for more complex fenestration systems, it is recommended that the fenestration product manufacturer be consulted for guidance on the appropriate effective wind area to use when calculating the design wind pressure for product specification purposes.ĪSCE 7-16 Components and Cladding 0.6 Rule Written into Chapter 26 Commentary: New simplified language in ASCE 7-16: For windows, doors and other fenestration assemblies, the effective wind area for typical single unit assemblies can be taken as the overall area of the assembly. For simple spanning doors (e.g.,horizontal spanning section doors or coiling doors), large specialty constructed doors (e.g., aircraft hangar doors), and specialty constructed glazing systems, the effective wind area of each structural component composing the door or window system should be used in calculating the design wind pressure. Ĭurrent language in ASCE 7-10: For typical door and window systems supported on three or more sides, the effective wind area is the area of the door or window under consideration. ![]() Senior Code Compliance Engineer PGT Custom Windows + DoorsĪSCE 7-16 Simplified Language for Effective Wind Area (Chapter 26 Commentary):
