As of March 1st, 2002, the state of Florida is requiring impacted resistant windows in designated areas (if not all of Florida).  There seems to be a lack of information about the availability of such windows.  Almost all the window manufacturers claim to have a line of windows which meets the current Dade county requirements that will be applied to the rest of the state (at least patially), but very few companies will show any documentation pertaining to the certification tests with their impact resistant windows.  Much less do any of the companies supply information with regard to energy efficiency.  The only exception that I can find is the Pella Window company that has a book listing all the important information.

1.)  Does anyone have a listing of the window companies that supply approved windows for new construction in Florida?
2.)  Does anyone have any information about energy efficiency with regard to impact resistant windows, or has everyone ignored that aspect of building just to comply with the new standards?

Sincerely,
