For the above address, the replaced impact, Windoor, SH360 and PW238. The minimum required wind
pressures below are based on FBC 2020 wind load calculations. The applied wind pressures are as follows per
the proposed replacement glazed units for Exposure D, 40 feet in height: (Respective NOA's: 20-0722.20
and 20-0519.13):
Series: Door or Window: Wind Zone: Applied Wind Pressure:
SH360 (5) 37"x72" windows 5 +50.8 / -65.9 psf;
PW238 (1) 37"x68" Picture Window: 5 +51.2 / -66.7 psf;
The mullion joining two SHM60, by WinDoor, NOA 20-0610.10 tributary loading meets above applied
presuures tranfered from those windows.
In reviewing respective NOA's and Florida numbers for the above units, the allowable respective design
pressures exceeds these respective applied pressures and as such is acceptable to this office
If you have any questions, please contact me at any time.
Thank you,
