Can Bay and Bow Windows Be Impact-Rated in Hillsborough County, FL?

Bay And Bow Windows Can Be Impact-Rated, But The Details Matter

That matters in Florida because impact protection is not just about the glass. If one part is undersized, the opening is not truly protected.

An experienced window replacement company can confirm the right build and paperwork before you order anything.

What Makes A Bay Or Bow Window Impact-Rated

To count as impact-rated, the whole bay or bow assembly has to meet Florida's hurricane requirements, not just the center window.
