Texas’ Leading Tornado Shelter
Will your family will be safe in a tornado? If you are asking yourself this question you have thought about how having a Tornado shelter at your home can offer you peace of mind.  Having a safe place to go in an emergency is an investment in the protection of your family. There are many different types of Tornado shelters available and understanding the differences between these units is the first step to making sure your investment goes as far as possible.

When thinking about buying a Tornado shelter, the type, size, material and installation are usually the initial considerations. Finding a shelter manufacturer that can be trusted and will be available for their customers should also be high on the priority list. It is essential to research and trust the company making this life saving product for your family. A company that can be trusted will have a history in manufacturing this type of product and be familiar with FEMA guidelines for ensuring safety during these deadly storms.

There are many sizes and shapes of Tornado shelters from very small to those able to protect entire communities. The size of a shelter needed is largely determined by the size of the family using it. Though most storms will not require long stays in a shelter, being sure there is comfortable seating and ample room for some emergency supplies is important.

Understanding the material a tornado shelter is manufactured from is the most important element to consider how long your shelter will last. The material a tornado 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.

There is also the consideration of below or above ground shelter protection. Being in the ground is the safest place to be in a tornado and an in-ground Tornado shelter designed to protect you in a tornado 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 any Tornado shelter is the door. For most underground units the door is the only part exposed to the tornado. Because the door being safe is such an essential part of being protected, FEMA requires shelter doors to be tested to withstand an F5 tornado.  Manufacturers of shelter doors that have gone through the FEMA testing should be able to verify that they have exceeded FEMA 320 or FEMA 361 requirements by documentation of the test.

There is a shelter that answers both safety and durability concerns. The Granger ISS is a rotationally molded tornado shelter made of polyethylene. The polyethylene construction of the Granger ISS will last longer than any other material on the market.  The door of the unit, also polyethylene, is both FEMA 320 and FEMA 361 exceeding. In addition there are many other benefits of this unit.

The Granger ISS Tornado 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 the possibility of installation in 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 including articulating hand rails, gas assisted shock system on the door, easy entry and exit and molded in seating.  It also comes with a lifetime warranty against material deterioration including cracking, leaking, rotting or rusting.
