Ocean Dr,Hutchinson Island, Fl 34952 Dear Mr. Laprade: Please know a wind load analysis was completed for the above window replacement, mullion installation and mullion fasteners as described below. The analysis included calculating the applied wind loads for the window replacement based on ASCE?-10 with (2) single hung and a middle picture window with total dimension of 108"x48"with(2)mullions sized at 1"x 2":0.375", plus (2) sliding glass doors at 72"x80"and(2)more at 108"x80",Exposure D, Wind speed 170 mph,Enclosed Structure, Category 11, with Wind Zones 4 & 5 and building height of 106'. When taking into account the external and internal pressure coefficients and adjustments per the ASCE7-10,the resulting and governing and most severe applied wind pressure comes to+72.3 psf/-77.6 psf which is less than the allowable NOA pressures and therefore acceptable to this office. The applied wind load on the Mullions is 480 lbs on each end. This is below the allowable wind load transfer from the window to the mullion when fastened to the mullion per the respective NOA 14-1105.01,Table 2A& 2B of 1,560lbs with(4) '/4"x2.5"tapcons,with min. 2.5"edge distance each end. To meet the satisfaction of this office and Florida Building Code, please ensure the single hung and picture impact rated windows and the sliding glass doors are installed per the window manufacturer's direction and as stated in their respective NOA's(15-0519.08, 15-0528.26 and 15-0106.08).
