Brighton, Mich.— July 15, 2020— Insulgard Security Products™, the industry leader in architectural security products, has introduced the advanced new STORMDEFEND™ TTH350 Door system – the first glazed aluminum door system Certified by UL to meet critical standards for use in tornado and hurricane storm shelters mandated by the 2015 International Building Code.

The STORMDEFEND TTH350 door system has been Certified by UL to meet ICC 500-14 and FEMA P-361-15 requirements for use in tornado and hurricane safe roams and shelters, including in the 250mph wind zone. A link to the listing can be found on the UL Online Certifications Directory. Key aspects of meeting ICC 500-2014 and FEMA P-361-15 include:

• Testing of smallest and largest site single and pairs of doors including pressure, debris impact and cycling.
• Testing of full assemblies including door, frame, glazing and hardware without substitution on both single and pairs of doors.
• Mandatory certification/labeling by a nationally recognized testing laboratory which includes periodic quality inspection.

In addition, the TTH350 door system meets UL 752 levels 1-3 for bullet resistance.

‘UL is excited that Insulgard’s fully glazed aluminum TTH350 door system has earned the UL Certification Mark to ICC 500-2014. Their TTH350 double door system is another example of some of the products UL certifies to rigorous hurricane and tornado storm shelter criteria that meet the requirements of the International Building Code as well as the FEMA P-361 guidelines,’ said Dave Stammen, UL’s Building Envelope Principal Engineer.

Insulgard continues to be at the forefront of designing and testing innovative new products that meet the stringent requirements for use in tornado and hurricane shelters. With the introduction of the new TTH350 door system, Insulgard is now able to offer a full line of architectural aluminum products meeting ICC 500-2014 and FEMA P-361.

As more states and municipalities adopt the 2015 or 2018 version of the International Building Code many new buildings, especially those in the 250mph wind zone, will include a tornado shelter. Section 423.3 and 423.4 of the IBC-2015 requires any new K-12 school, emergency operation center, police station and fire rescue station built in the 250mph wind zone include a tornado safe room. It also stipulates the storm shelters and all components used in the storm shelter meet ICC 500-2014.
