Designers and builders can choose from a variety of features to help minimize losses from high winds. The choice of features will depend on the severity and type of local wind events, but the entire continental United States is exposed to high winds. This is especially true for tornado and hurricane high-risk zones.  Measures are available to fortify all typical construction types, including concrete, masonry, wood frame, and structural insulated panels. Features may include structural strapping and bracing, wall cladding; roof sheathing and coverings; fortified entry doors, garage doors, windows, and skylights; and soffit and overhang design. Unvented attics can minimize pressure differentials that can destroy roofs and can reduce opportunities for wind-driven rain to enter the structure. This can be accomplished with closed-cell spray foam applied under roof decks or with structural insulated panels.
