This tool assists in interpolating between the corner & interior wall wind zones 4 and 5 using ASCE 7.

Typically zone 5 corner negative (suction) pressures are higher than a building’s interior zone 4 pressures which may restrict the glazing product 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 this firm by requesting a review & certified results.
