Abstract: A hurricane and severe weather protection system for protecting an opening in an associated structure includes a first panel having a first outer surface and a core with a lower density and connecting means for connecting the first panel to the associated structure. The panel is formed of a single PVC material or polycarbonate. A panel is customized to properly fit the opening. An insert is then positioned into a frame member near the opening. Next, a thumb turn is partially screwed into the insert. After the bottom portion of a slot in the panel is placed over the thumb turn, the panel is slid downward until the thumb turn contacts the top of the slot. Finally, the thumb turn is tightened.
