A new group, the Impact Window Affordability and Safety Association (IWASA), is fighting the implementation of part of the Florida Building Code. The organization, consisting of seven door and window companies in Florida, objects to provisions of the latest version of the code, which increases energy efficiency requirements for impact doors and windows. Opponents claim that because a significant portion of their work consists of replacing fenestration in existing buildings that are not being renovated, they will be required to “incur substantial costs in connection with testing and retooling for new windows.”
