It is imperative that the builder, code official, manufacturer and anyone else involved in choosing or approving the windows, doors or skylights for a particular residence be aware as to whether the 0.6 conversion factor is appropriate or not, and which set of provisions is being used to determine the design wind pressures for the home. For vertical glazing, this reduction in design wind speed in ASCE 7-16 results in a reduction in design wind pressure. Figure 1 - SILL WIDTH AND SLOPE 0000014419 00000 n 1.
