Image
Image
Advanced framing techniques include constructing on a 2-foot grid where wall studs are placed 24 inches on center and aligned with roof and floor trusses for a continuous load path from roof to foundation.
Image
Advanced framing techniques including 2x6 walls spaced at 24 inches on center and ladder blocking at wall intersections allow more space for insulation in the wall cavities while open-web floor joists provide space between floors for ducting.
Image
Image
After spraying the 2x6 wall cavities with 2 inches (R-13) of closed-cell spray foam, the walls are covered with netting and an additional 3.5 inches of fiberglass (R-13) is blown in.

Air seal the common wall between units in a multifamily structure to minimize air leakage.
Image
Angle support framing is added to brace a long gable overhang constructed using the ladder framing method.
Image
Attach the interior 2x4 wall to the exterior wall top plate with a flat metal connector plate
Image

Image
Closed-cell spray foam insulation is added to the wall cavities of an existing exterior wall
Image
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
Connecting hardware helps tie the walls to the top plates and rim joists to ensure a continuous load path to improve a building’s resistance to high winds, floods, and earthquakes.
Image
Image
Construct a double wall consisting of two framed walls forming a wide wall cavity for more insulation in the home’s exterior walls.

Drywall was removed and the existing 2x4 walls were filled with 3.5 inches of dense-packed cellulose. Outside, the ½-inch plywood was topped with house wrap, 1.5 inches closed-cell rigid foam, 1x3 furring strips, and fiber cement siding.
Image
Each floor of this two-story modular home is constructed in a factory, including the 2x6, 24-inch on-center walls, R-21 fiberglass batt cavity insulation, and rigid exterior foam, housewrap, windows, and trim, then connected on site.
Image
End wall failure under hurricane force winds due to inadequate bracing of the gable end wall.
Image
Example A of a gable truss and gable end wall bracing for a home in a hurricane region

Image
Gaps at shared common walls can be a significant source of air leakage in multi-family buildings
Image
Headers over windows on non-load-bearing walls are open to allow room for insulation.
Image
How to properly anchor a new home to its foundation with foundation sill plate, stem wall, and footing
Image
Image
ICFs provide continuous wall insulation from the roof to the footing with very little thermal bridging
Image
Improper continuous load path design lacking bracing results in the failure of gable end walls under high wind conditions.
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 regions, special hardware is used for most framing connections; toe-nailing is not acceptable.
Image
Image
Installing ladder blocking at interior-exterior wall intersections rather than three solid studs in the exterior wall as the supporting surface allows room for insulation in the exterior wall.
Image
Insulating sheathing is extended up to the roof rafters and sealed around the framing with spray foam as part of this exterior wall retrofit
Image
Interior non-load bearing walls are 2x4 studs spaced 24-inchon- center, can have non-structural connectors
Image
Interior wall attached with top plate metal connector, drywall clips support drywall, plan view

Image
Key connection points for a continuous load path for earthquake and high wind disaster resistance
Image
Image
Ladder blocking where interior and exterior walls intersect uses less wood and provides more room for insulation than stacking studs in the exterior wall to nail the interior wall to.
Image
Image
Image
Ledger board, metal brackets, and vertical 2x4s have been installed in preparation for exterior spray foam in this retrofit exterior wall insulation technique
