As Mike pointed out, there are a number of conflicting and overlapping code issues involved. For example, Kritlyn's orginal question concerned impact glass. Technically, impact glass isn't actually required anywhere. A homeowner can use shutters or even plywood (with certain requirements/restrictions for plywood) and not need impact glass. Windzone requirements specific to impact glass are spelled out in ASTM E1996-05 and include several levels of protection required anywhere from a garden shed to "essential" structures such as hospitals, schools, police and fire stations. Within the windzone guidelines are levels of testing for the different types of structures within the specific windzones. It isn't particularly complex, but it is involved. The specific requirements do separate roof windows from vertical windows for example and also windows that are above and below 30'. As Mike pointed out, local codes can become much more (or less) restrictive and much more specific. Design Pressure, or DP, requirements also vary by location and windzone. DP is NOT necessarily indicative of an impact product. That is why some manufacturers can get away with saying they sell "hurricane" windows that are not impact resistant - they have met windload Design Pressure requirements, but remember that that window isn't specifically protected from the neighbor's flying lawn furniture in the event of a storm. It will require something to protect it from an impact. DP ratings do apply to specific windspeeds and as such may be mandated in certain areas. Often, the requirement is specified by the architect or engineer designing the home or the protection for the home...and it is quite possible to have different requirements for windows in the same house based on orientation and location (such as near a corner).

I believe that Hurricane windows,provide superior protection during a violent storm. As they are attached to the integral part of the structure of a building,prevents chances of wind entering the building,something like storm shutters. Simultaneously i even let light enter a room. -------------------------------------------- The hurricane windows fort lauderdale servers great !!

For further reference Mullion/muntin: A mullion is a heavy vertical or horizontal member between adjoining window units. Muntins are the narrow strips of wood that divide the individual panes of glass in a traditional sash.May 24, 2008
