Greenheck’s new FEMA Model FSG-801 fabricated steel grille protects exterior wall penetrations on FEMA 361 or 320 compliant storm shelters or safe rooms. Fabricated of 0.25 inch thick hot rolled steel and designed with inverted V-style blades, it allows high free area and very little airflow resistance while providing maximum protection against extremely high wind-load and wind-borne debris. It is most frequently installed in front of louvers on the building’s exterior.
