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

Bay and bow windows can absolutely be built as impact-rated assemblies in Hillsborough County FL, but they are not as simple as swapping in a stronger pane.

That is why homeowners comparing hurricane windows vs storm shutters for Brandon FL homes after Hurricanes Milton and Helene are usually deciding between two different strategies. One is to protect the opening with a rated window. The other is to keep a standard window and rely on removable protection before a storm.
