Image
Externally insulated post-tensioned concrete slab-on-grade foundation wall with a turn-down footing showing anchorage of the wall to the foundation for seismic resistance
Image
Failure of a freestanding concrete masonry end wall due to discontinuous tie-beam when exposed to hurricane force winds.
Image
Image
Fire barriers for ventilated wall cavities use thermally activated expansive materials to close off the ventilation space between the wall cladding and the sheathing during a fire while allowing air flow through the metal mesh during normal conditions
Image
Fire barriers for ventilated walls use heat activated intumescent expansive materials to close off the ventilation space between the wall cladding and the sheathing during a fire while allowing air flow through the metal mesh during normal conditions
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
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
Ice dams formed by melting of snow on roofs can affect roofs, walls, ceilings, siding, and insulation.
Image
Improper continuous load path design lacking bracing results in the failure of gable end walls under high wind conditions.
Image
Improper flashing can allow rain water into walls, causing significant damage
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
In hot climate zones, shade building surface with vegetation for passive cooling.
Image
Incorrectly done seismic retrofit, the plywood sheathing is not nailed to the mud sill and therefore it is not providing any shear strength
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.
Image
Image
Image
Install shingle starter strip then kick-out diverter; attach to roof deck but not sidewall
Image
Image
Install the house wrap. Cut house wrap to fit over diverter and tape top of cut wrap
Image
Image
Image
Image
Insulating sheathing is installed on exterior of an existing framed wall with water control between existing sheathing and insulating sheathing
Image
Image
Image
Key connection points for a continuous load path for earthquake and high wind disaster resistance
Image
Light colors have been used on exterior walls and roofs to keep buildings cooler in hot climates for centuries, as shown by this traditional building in Morocco, built in the early 1800s

Location of Braced Wall Panels and Braced Wall Lines, Figure R602.10.2.2 in the IRC

Lower-story wall anchorage to masonry (or concrete) base. Straps properly nailed at wall studs.

Image
Moisture-resistant plastic and fiber cement exterior trim and cladding are indistinguishable from wood building elements.
