Resilient Construction

Resilient Wood Construction Resists Wind, Weather,
Seismic Forces & Moisture

Wood is the resilient choice for construction. Wood's strength combined with its ability to absorb stresses or impacts without weakening or degrading make wood a superior building material, especially in areas susceptible to severe weather conditions or seismic activity. While regionalized building codes address the necessary design requirements, APA provides additional resources detailing construction practices that help structures perform even better against hurricanes, high winds, severe moisture and earthquakes. 

Plywood and OSB Sheathing Boost Structural Strength

The overall strength of a building is the function of all of the components—walls, floors, roof, and foundation—working together as a unit. When an earthquake or high wind strikes the house, the walls and roof bear the brunt of these forces. A fully sheathed wall of plywood or OSB, properly connected to the foundation below and roof above, is a strong barrier that resists the persistent forces of wind and earthquakes. Laboratory tests and field evaluations show that sheathing with plywood or OSB can help make a house two to three times more able to withstand high winds and earthquakes.

Protect Your Home from Windstorm Damage with Hurricane Shutters

 

T450Hurricane Shutter Designs
Shutters over large windows and glass doors can help prevent windstorm damage. Hurricane Shutter Designs, Form T450, includes five hurricane shutter designs with recommendations for a variety of window and door openings in masonry and wood-frame buildings. Designs include illustrations, materials lists, and step-by-step instructions. Details are also available for Latin America in Spanish.

Hurricane Shutter Design Considerations for Florida, Form T460, is a regionalized version of the Hurricane Shutter Designs publication specific to Florida.
