Extra-wide air sealing tape seals seam where the structural insulated panels (SIPs) that form the roof and walls meet.
Image
Extruded polystyrene (XPS) rigid foam is taped at the seams to provides a continuous air and weather-resistant barrier so no house wrap is needed; it also provides a continuous layer of insulation.
Image
Faced fiberglass batt insulation can be stapled to the stud faces or slightly inset, but avoid compressing the batts

Image
Image
Image
Four inches of rigid foam separate the concrete slab from the ground and the foundation walls.
Image
Framing is built around the window before exterior rigid foam is installed on the exterior walls around the window.
Image
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
Hand tools for cutting fiber board sheets include a knife, straight edge, and color-coded edge-cutting tools
Image
Heated or partially heated garages with podium decks should be thermally isolated from both ambient exterior space and interior conditioned space by insulating the interior of the garage walls and ceiling and extending the insulation below grade.
Image
Heated recirculation plenum spaces can be installed in parking garages in cold climates to prevent pipes from freezing and warm the floor of occupied space directly above the garage.

High-density closed-cell spray foam insulates the attic of this home in New Orleans.
Image
High-density fiberglass pipe insulation comes with a vapor barrier cover and self-adhesive seam
Image
Holes in the exterior walls are flashed and flashing is integrated with housewrap before installing rigid mineral wool insulation.
Image
Image
HVAC ducts can be encapsulated in 3 inches of closed-cell spray foam, then buried in R-49 of blown fiberglass insulation after the ceiling drywall is installed in the vented attic.
Image
Ice dams formed by melting of snow on roofs can affect roofs, walls, ceilings, siding, and insulation.
Image
ICF bricks are stacked to form hollow walls that are reinforced with steel rebar before the concrete is poured in
Image
ICF foundation walls wrap the floor slab in R-22 of insulation while the entire space under the slab is covered with 4.3 inches of closed-cell spray foam.
Image
ICF walls and an attic sealed and insulated to R-63 on the underside of the roof deck with 10 inches of open‐cell spray foam plus 2.7 inches of closed‐cell spray foam provide a complete thermal break around this home.
