What Makes The Slate Secure/Granger ISS Storm Shelters Different From All Others?
There are many different shelters available as anyone who has looked into purchasing one probably already knows. But, not all shelters are created equally and understanding some of the differences between units can help you make sound investment. The Granger ISS is a rotationally molded in-ground Polyethylene which has a half-life of 10,000 years. Unlike traditional in-ground shelters, the Granger ISS unit with its patented design is guaranteed
not to float out of the ground.
It is impervious to the elements, and able to withstand temperature changes, without cracking, non-toxic and practically
maintenance free.
