Insulgard’s STORMDEFEND TTH350 door system has been tested and certified by Underwriters Laboratory to meet ICC500-14 and FEMA361-15 requirements for use in tornado and hurricane safe rooms in the 250mph wind zone.

As part of this certification, the largest and smallest single and pairs of doors have been tested and listed by UL. The TTH350 doors also meet UL752 level 3 for bullet resistance.

It is important to note only the hardware that has been tested can be supplied on these doors. Please be sure to review the tested hardware list to be sure it meets the project-specific requirements. Also, these doors can only be glazed with TORGARD 30 Glazing.
