The United States experiences more tornado activity than any other country in the world. Engineers at the USDA’s Forest Products Laboratory (FPL) have developed a residential wood tornado shelter that meets industry safety standards and can be built in an existing home by advanced DIYers. This TechSpec presents an overview of this tornado shelter’s design and construction process. In addition to this TechSpec, you may also be interested in the companion six-part video series on the Home Innovation Research Labs YouTube Channel as well as the step-by-step Construction Guide.
