The door of the Granger ISS Storm Shelter is a unique design that includes a double wall polyethylene exterior panel, a double wall polyethylene interior panel and a sheet of polycarbonate bolted between for ultimate safety and near absolute protection from storms and tornadoes.

    Dual Gas Assisted Shock System – Any door designed to protect you against a tornado is going to be heavy. Though lighter weight than other materials the polyethylene door of the Granger ISS is no exception.
