Not everyone knows about the subject . Florida building code will be outdated soon . ( 100 mph inland standard ) International building code is130mph . The new standard Miami-Dade code is 150 mph wind and also a 2×4 impact test . The only products to buy are this standard . Overlap on basic panel types Aluminum or clear Protexan corregated panels is 3″ on all sides . Current bolt width of panels is 12″ . Fixed stud mounting gives you no option of interchanging different width panels . I recommend fixed ” H ” tracks on top ( slip fit ) and fixed ” F” tracks on bottom tracks ( sliding removable bolts ) . You may mount your panels horizontal to save material with fixed studs but sidewalk bolts offer fixed location and low profile heads off season . Top tracks can be calked and painted color of building . Lower tracks sit just underneath the window sill . Both are available in flush , 1″ and 2″ buildout . Self installation is not difficult through cement block , although solid sills are hard to drill and bolt . Ex. ( patio door ). Install for the do it your selfer saves 25% . I sell these products in my . store Hurricane Home Protection Home-Hurricane-Protection Everything is 150 mph rating .Full documentation is available for permiting Thanks for reading -Dave.
