Example of the advanced framing technique, double-stud wall cavity, which will later be filled with blown insulation
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
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
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
Ice dams formed by melting of snow on roofs can affect roofs, walls, ceilings, siding, and insulation.
Image
Image
Insulating sheathing is installed on exterior of an existing framed wall with water control between existing sheathing and insulating sheathing
Image
Image
Image
Right - Foil-faced polyisocyanurate rigid foam is attached to the existing exterior wall with vertical wood furring strips
Image
Right - These raised heel roof trusses provide 16 inches of space over the outer walls for full insulation coverage at the attic perimeter.
Image
Right - This foil-faced polyisocyanurate rigid foam is installed on an existing exterior wall and the seams are taped so the rigid foam can serve as a water control layer
Image
Right - XPS foam insulation is attached to the existing exterior wall with wood furring strips that serve as a nail base for the siding and are installed vertically to allow for drainage and drying behind the siding
Image
Right – Furring strips provide a drainage gap between the rigid foam and the siding.
Image
Right – This foil-faced foam sheathing has taped seams and proper flashing details so it can serve as a drainage plane.
Image
Rigid foam insulation can serve as the drainage plane when all seams are taped. Furring strips provide an air gap behind the cladding.
Image
Step 4. Install insulating sheathing and vertical furring strips on the retrofitted exterior wall; seal around pipe or duct with urethane sealant.
Image
Step 5. Install sheathing tape flashing over the duct or pipe and wood blocking on either side for later attachment of trim.
Image
Step 6. Install vent hood trim block, metal cap flashing; seal top edge of flashing with sheathing tape.
Image
Image
Step 8. Attach the new cladding to the furring strips over the rigid foam for the exterior wall retrofit.
Image
Tape horizontal joint with minimum 3" wide tape placing tape offset high on the joint, adhearing to the upper sheet without wrinkles
Image
Terminate 4" tape with 2" wide tape placing tape offset high on the joint, 2/3 of the tape should be adhered to the sheet of insulation
Image
Image
This basement is insulated on the exterior with rigid foam over dampproofing, with granular backfill and footing drains to facilitate drainage away from the foundation, a termite shield to protect from pests, and cellular PVC to protect the rigid foam.
Image
This exterior insulated slab-on-grade monolithic grade beam foundation is protected from pests by termite shield at the sill plate, borate-treated framing, flashing at end of wall insulation, brick veneer over slab-edge insulation, and rock ground cover.
Image
This home has heat loss through the roof, leading to ice dam formation and structural issues during winter months.
Image
This hot climate zone home uses high quality batt insulation between studs to insulate this connecting garage wall.
Image
This hot climate zone home uses high quality batt insulation to insulate truss-joist headers.

Image
Image
Wrong – Either this tape was not pressed down firmly or the surface was wet or dirty so the tape is not sticking properly even during construction.
Image
Wrong – If the insulated sheathing will serve as an air barrier and drainage plane, any cuts and seams must be taped or sealed.
