Image
Expanded polystyrene insulation is installed with joints taped and lath attached in preparation for the application of stucco
Image
Extension boxes of plywood built around the windows on this wall retrofit will be flush with the outer layer of exterior rigid insulation
Image
Exterior fiberglass insulation on this new home was (incorrectly) cut to terminate below-grade after backfill, which will expose the above-grade portions of the foundation wall to cold temperatures
Image
Exterior surface of below-grade walls finished as follows: For poured concrete, concrete masonry, and insulated concrete forms, finish with damp-proof coating
Image
Exterior surface of below-grade walls finished as follows: For wood-framed walls, finish with polyethylene and adhesive or other equivalent waterproofing
Image
Exterior XPS basement insulation is correctly installed to completely cover the foundation wall
Image
Externally insulated concrete slab-on-grade foundation with a turn-down footing, showing anchorage of the wall to the foundation for seismic resistance

FEMA recommends techniques like open lower wall cavities with exterior rigid foam insulation and paperless drywall for flood-resistant, dryable wall interiors.
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
Floor cavity air pressure is measured by placing a tube into the floor cavity through a small drilled hole
Image
Floor cavity pressure is measured by inserting a tube into the floor cavity using an extension pole

Image
Frame, insulate, and air seal the walls of the skylight shaft as you would an exterior wall

Image
Furring strips provide a mounting surface for siding over the smart house wrap membrane which serves as a drainage plane over cork insulation installed on the exterior of this home.
Image
Furring strips provide drainage gap behind lap siding; screen is added at bottom and top to prevent entry of insects and wildfire embers.
Image
Image
Gaps at shared common walls can be a significant source of air leakage in multi-family buildings
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.
