IONCON has developed designs and is familiar with design criteria to comply with high wind standards applicable to tornados and hurricane prone areas. These designs go over and above typical code requirements and loading calculations by a significant amount with the intention of protecting occupants from 200+mph winds and flying debris/missles. A ‘Large Missle’ is usually defined as a 15lb 2×4 board making a impact on the building at 100mph.
While a whole house may be designed from the beginning with these criteria in mind those with a existing homes may find it more reasonable to retrofit a ‘safe-room’ or ‘storm-shelter’. IONCON is familiar with these designs along with other traditional cellar, wine cellar, bunker, and bomb-shelter type designs.
