How to Read a Florida Product Approval Number on Windows
What That Number On The Window Label Really Tells You If you work on coastal homes long enough, you learn that the small print matters almost as much as the glass itself.

If a window does not line up with the approval record, an inspector can flag it, and a contractor may need to replace or document it again.
