This tool assists in interpolating between the corner and interior wall wind zones 4 and 5 using ASCE 7-10 or ASCE 7-16.

Typically zone 5 corner negative (suction) pressures are higher than their neighboring zone 4 pressures prohibiting glazing rated to limiting pressures from being installed.

Using this tool, interpolated pressures can be determined that may permit a lower product limiting pressure. Results could be reviewed and certified for permit by an engineer of the firm by clicking below.
