A gut rehab that includes drywall removal provides the opportunity to thoroughly insulate the walls.
Image
A typical Las Vegas hot-dry climate home made of wood frame construction and insulated with R-25 expanded polystyrene externally over a drainage plane, with an unvented wood frame insulated attic and roof assembly.
Image
Adding air-sealing and rigid foam insulation at the wall-to-overhanging floor juncture at the outside corner of an existing home
Image
Advanced framing details include corners that are constructed with fewer studs or studs aligned so that insulation can be installed in the corner.
Image
Advanced framing details include framing aligned to allow for insulation at interior-exterior wall intersections.
Image
Image
Advanced framing details include open headers and reduced framing around windows and two-stud corners to allow more room for insulation in the wall cavities while reducing lumber costs.
Image
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
After attaching netting to the 2x6 studs, workers fill the wall cavities with R-23 of blown fiberglass made from recycled bottles.
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 floor joist cavities under kneewall with rigid foam, plywood, or OSB caulked in place
Image
Image
An installer fills these wall cavities with spray foam insulation, which will be trimmed flush with the stud faces after it dries and hardens.
Image
Attach the interior 2x4 wall to the exterior wall top plate with a flat metal connector plate
Image
Baffles will keep insulation out of the soffit vents and wind out of the insulation in this vented attic.
Image
Because the above-grade potions of the wall lack exterior insulation, condensation and even ice form during cold winter conditions
Image
Brick veneer framed wall supported by a concrete slab-on-grade foundation with a turn-down footing insulated on its top surface, showing anchorage of the wall to the foundation for seismic resistance
Image
Capillary break at all crawlspace floors using ≥ 6 mil polyethylene sheeting, lapped 6-12 in., and lapped up each wall or pier and fastened with furring strips or equivalent
