FEMA 361

FEMA 361 products are used to protect air intake or exhaust openings from flying debris caused by tornadoes spawned by hurricanes or severe thunderstorms. FEMA 361 products must also withstand extremely high wind loads. FEMA 361 products must be applied over any wall penetration on a FEMA 361 storm shelter. FEMA 361 products are most frequently installed in front of louvers on the building exterior.
