Tornado Resistant ICF Homes
With the ever present threat of tornadoes and other severe weather, many people in the midwest and south have begun to take the
precaution of building a tornado safe house or safe area within their house. Generally, the safest place to be when a tornado hits is in a
basement, but when that is not an option you want to be in an interior room in your house with no windows.
In the aftermath of some of the recent tornadoes it has been seen time and again that while most houses are at the mercy of the storm, in
many cases the only houses left standing are the ones that were built with ICFs. So some people who cannot afford to build a new ICF
home have taken the step of building a small "tornado safe house" using insulated concrete forms on their property where they can go in
the event of a tornado. Another option is to use ICFs to build an area within the house or attached to it, where a family can keep valuables
and stay to ride out a storm.
Most of the major manufacturers of ICFs, including Fox Blocks, Amvic, Buildblock now promote the idea of the tornado safe room or safe
house. In addition to protection against tornadoes, ICFs have proven to be hurricane resistant and provide tremendous savings on energy
