IBHS researches ways to improve commercial building performance in high-wind events. Results of this research inform IBHS guidance on methods and materials for commercial construction.
In 2012, IBHS performed a demonstration to compare and contrast the high-wind performance of two full-scale commercial structures—one built using common construction practices and the other using stronger wind-resistant methods and materials. Both structures were equipped with FM Global approved roofing assemblies, including the roof cover, roof deck, perimeter flashing and insulation. The difference between the structures is that for the stronger building, these components were also installed according to FM Global Standards. Both buildings were subjected to simulated high-wind events modeled after real-world thunderstorm and hurricane conditions.
