Granger ISS Tornado Shelter Door FEMA 320/361 Testing

Being under the ground is the safest place to be during a tornado and an underground shelter designed to protect you in these storms is safer than any basement. Above ground shelters are available but being above ground simply is not as safe as being in the ground. The most important part of an underground storm shelter is the door. Doors that have been tested to withstand an F5 tornado will be able to verify that they have exceeded FEMA 320 requirements.

Underground Storm Shelter Materials

The material an underground shelter is made from dramatically influences maintenance and lifespan of this type of product. Some materials deteriorate much faster than others, especially if they are buried in the ground. Different shelters need different degrees of maintenance which can include painting, cleaning, patching cracks or deterioration, oiling hinges, inspecting latches and scraping rust. Review some of the more commonly used underground tornado shelter materials in the chart below.

This shelter has a double wall design which is foam filled for extra rigidity and strength. The foam also acts as an insulator making the interior of the shelter more comfortable. The Granger ISS has a reverse taper design which does not require the unit to have an anchoring system. This means a faster easier installation and that it can be installed in many areas other underground shelters would have issues. Regardless of soil condition, water tables or almost any space construction, this shelter installs in 4 hours or less, seats six or more, has a number of additional safety features and comes with a lifetime warranty against material deterioration including cracking, leaking, rotting or rusting. The experience and dedication of Granger Plastics Company exhibits in manufacturing and safety standards has given peace of mind to people across the world.
