Built to handle wind speeds of 250 mph, these tornado-resistant windows are ideal for safe rooms, community shelters, or school and government facilities. They offer protection against air pressure and flying debris and meet current FEMA 361 and FEMA 320 requirements. For added visibility and an inflow of natural light, the windows come with a clear or stippled pattern. They fit seamlessly into any new or existing project, are factory built, and require virtually no maintenance or window treatments.
