A plastic fiber drainage mat rainscreen provides uniform support for the siding and allows moisture to flow horizontally and diagonally in addition to vertically.

A raised wood pier foundation can raise the subfloor above the design flood elevation.

Building America worked with Mercedes Homes in east Florida to design homes using cast-in-place concrete walls capable of withstanding wind-blown debris impacts of up to 200 mph (Source: Mercedes Homes).

Buildings damaged by a hurricane storm surge: upper homes on gulf shoreline were hit by large waves above the lowest floor, lower left home on bay and right school 1.3 miles from gulf shoreline were hit by surge and small waves.

Connecting hardware helps tie the roof to the walls to ensure a continuous load path to improve a building’s resistance to high winds, floods, and earthquakes.

Image
Example of masonry construction. Wall separated from building envelope due to inadequate vertical wall reinforcing in connection to horizontal tie-beam.
Image
Failure of a freestanding concrete masonry end wall due to discontinuous tie-beam when exposed to hurricane force winds.
Image
Image
Firewall separation. Results from building corners being discontinuous with tie-beams.

Image
Good water management practices like sloping grade away from house, and installing gutters, perimeter drain pipe, a capillary break, and free-draining soils or drainage mat protect the foundation from water saturation.
Image
House wrap is sealed at all seams and overlaps flashing to serve as a continuous drainage plane over the exterior walls.
Image
Hurricane force winds that breach external windows and doors can then cause failure of the entire building due to internal pressures on walls and roof.
Image
Hurricane straps, hold-down connectors, and bolts help to transfer loads from the building’s walls to its foundation, increasing resistance to vertical and horizontal pressures acting on the building from wind, waves, or ground movement.
Image
Image
Improper continuous load path design lacking bracing results in the failure of gable end walls under high wind conditions.
Image
Image
In areas prone to high winds and hurricanes, double vertical “jack trim” and horizontal “header” and “sill” studs are recommended on all sides of window and door openings.
Image
In high wind areas, provide lateral support to masonry end walls to resist high winds.
Image
In high-wind regions, special hardware is used for most framing connections; toe-nailing is not acceptable.
Image
Image
Install all layers of the drainage plane to overlap, not underlap, to direct bulk water down and out of the wall.
Image
Install furring strips over house wrap to provide a rainscreen behind wood siding.
