Key connection points for a continuous load path for earthquake and high wind disaster resistance
Ladder blocking where exterior walls intersect interior walls provides more space for insulation and reduces thermal bridging.
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.
Ledger board, metal brackets, and vertical 2x4s have been installed in preparation for exterior spray foam in this retrofit exterior wall insulation technique
Many hardware stores sell appliance bracing kits to secure the water heater to wall framing with metal straps
Marriage joints between modular home modules at all exterior boundary conditions fully sealed with gasket and foam
Metal Flashing Material Table
Metal straps tie the roof rafters to the top plate for additional resistance to severe storms.
On top of the ice-and-water shield, the builder installed horizontal beams that were raised 6 inches off the deck to allow room for spray foam insulation.
Open-web floor joists provide space for ducts between the floors of a two-story home.
Permanent options for keeping sun off windows to minimize solar heat gain include permanent overhangs and awnings, frames, and louvers.
