Georgia Storm Shelter Features

The Granger ISS Storm Shelter is the only Underground Storm Shelter manufactured by an internationally recognized manufacturing leader who has produced Underground Shelters, for nearly twenty years. The Granger ISS Underground Stom Shelter comes complete, ready for installation when it arrives at the installation location. Unlike many less innovative Shelters, the Granger ISS does not require an anchoring system in most typical installation scenarios. This allows for faster and less expensive installations. An added feature of the Granger ISS is that without an anchoring system, the unit can be moved in the future if necessary.

When most families are thinking about the investment of a Storm shelter, they are taking a concious effort in providing the safest environment possible for their family. For many, acquiring an underground shelter is an investment into their family security for many years to come. Storm Shelters come with a wide range of features. Some underground tornado shelters offer basic defense without offering any type of "comfort features" such as lighting, seating or carpeting. Many of these underground shelters are made from inferior materials that will immediately begin to deterioriate once placed in the ground, such as concrete or steel. Some shelters do not even provide the spacing for any occupants to stand in! The Granger ISS Storm Shelter is not only one of the most durable Tornado Shelters in the industry, it additionally supplies a complete array of features and amenitites.

    Tornado Shelter Doors

    Many underground shelter doors are designed and produced from inferior materials, that do not stand up to oxidation and UV rays. Between the degradation of the door materials from the Ultra Violet rays and the deterioration of the door due to moisture and oxidation, many of these inadequately designed and built made doors will soon come to be safety threats more so than required security for their underground shelters. Take notice in the photos listed here how various other tornado shelter doors produced from inferior materials degrade in every day settings.

    Fiberglass Door: A future liability issue?

    If you notice in the picture above and to the right, the door has an internal shock to make opening and closing the door easier. However, due to poor design and engineering, the manufacturer has chosen to locate the shock on the interior of the door. This creates a potential safety hazard, for the occupants of the shelter. If/When the door was to be impacted, the shock could be propelled into the safe compartment of the shelter. Don't put your family's safety at risk! Ask to see the FEMA 320/FEMA 361 video and a copy of the report from the Debris Impact test facility!
