Purchasing impact-rated windows based on the sales pitch will get you every time. They are tested to the same water penetration standards as regular windows.
Impact windows still break, still leak and are 3-4 times as expensive to replace after they break. For these reasons they are a poor first line of defense against storm damage. An approved hurricane shutter system is the best way to protect any window (impact-rated or regular) against storm damage.
Do your homework and do online research in window forums and learn from the lessons of other homeowners. Listening to those who rely on the window industry for their paychecks will not get you all of the facts.
