Thank you for visiting Jim Giles' CERTIFIED Safe Room's web site and giving our product consideration. First off, let me tell you what our mission is and why we are in this business. Jim Giles' CERTIFIED Safe Rooms is not just any tornado shelter company. If we were, then we would offer more types of products, like below ground cellars etc. No, this company was founded by a career meteorologist, the late Jim Giles, whose career spanned more than 40 years in three different fields of weather, including a weather forecast commander in Vietnam during the 1960s, a University Professor of meteorology and of course a Meteorologist on TV in Austin and Dallas, Texas before he became a television icon in Tulsa, Oklahoma for more than 25 years. Jim's passion was to keep you and your family safe.. 4'×4' Safe Room 4'×6' Safe Room 4'×8' Safe Room 6'×8' Safe Room 8'×8' Safe Room 8'×12' Safe Room
