Image
Special molded corners provide continuous insulation layer at the corners to improve structural strength and minimize thermal bridging
Image
Image
Spray foam extends down the inside of the foundation wall to the uninsulated slab; because the wall lacked exterior perimeter drainage, the slab was cut and an interior footing drain was installed.
Image
Spray foam is installed between new studs over the existing siding in this deep energy retrofit
Image
Spray foam provides a critical seal between the subfloor, rim joist, and sill plate
Image
Image
Step 1. Apply roof underlayment over roof deck and up the sidewall over the rigid foam insulation
Image
Step 1. Remove the existing wall cladding to prepare to retrofit an exterior wall.
Image
Step 2. Install a continuous air and water control layer over the existing wall sheathing.
Image
Step 2. Install shingle starter strip then kick-out diverter as first piece of step flashing.
Image
Step 3. Apply urethane sealant around the duct or pipe in the retrofitted exterior wall.
Image
Step 3. Place the first shingle and the next section of sidewall flashing over upper edge of diverter
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 4. Install remaining sidewall flashing, appropriate counter flashing, and shingles
Image
Step 5. Apply self-adhesive flashing over top edge of the wall flashing, diverter, and rigid foam insulation
Image
Step 5. Install sheathing tape flashing over the duct or pipe and wood blocking on either side for later attachment of trim.
Image
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
Step and kick-out flashing at all roof-wall intersections extending ≥ 4 in. on wall surface above roof deck and integrated with drainage plane above
Image
Structural insulated panels offer a continuous layer of thermal protection and draft resistance around the home and come from the factory precut for fast assembly.
Image
Structural insulated panels provide a continuous layer of insulation sandwiched between two continuous layers of OSB for thermal protection and sturdy construction.
Image
Image
Stucco is installed over rigid insulation, which is installed over a drainage plane consisting of a drainage gap and building wrap layer over the sheathing
Image
Stuff cavities under kneewalls with rolls of fiberglass batt and spray foam in place
Image
Tape horizontal joint with minimum 3" wide tape placing tape offset high on the joint, adhearing to the upper sheet without wrinkles
Image
Tape the joint between the top insulation sheet and the Z-flashing with 2" wide tape to improve air tightness
Image
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
The “institutional” perfect wall works in all climate zones; water, air, vapor, and thermal control layers are exterior of the sheathing, assembly allows drying to interior and exterior
Image
Image
The 2x4 wall studs are staggered along the 2x6 sill plate providing space to weave insulation around each stud to stop thermal bridging through the wall.
