Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Image
Right: All joints in the rigid foam are taped to keep stucco out of joints for even drying. Mesh tape (shown here) is used with expanded polystyrene (EPS); acrylic sheathing tape or self-adhered membrane is used with XPS

Rigid insulation and air-sealing can be used to thermally isolate garages from interior occupied space in multifamily row houses/townhouses.
Image
Rigid insulation and air-sealing can be used to thermally isolate garages from multifamily row houses/town houses with basement foundations in IECC Climate Zones 3 or higher.
Image
Rigid insulation can be used as a thermal break between a garage slab with a heated plenum space and a separately cast garage slab without a heated plenum space.
Image
Image
Scaffolding is continually raised as courses of foam brick are added so that the pour man can see both sides of the wall during the pour.

Single framed wall converted to double wall and insulated with open-cell spray foam
Image
SIP panel walls are less susceptible to air leakage and convection issues than stick-built walls
Image
SIP panels should be stacked high, dry, and flat
Image
Image
Smoke generators are used to identify air leakage sites during depressurization testing
Image
Special molded corners provide continuous insulation layer at the corners to improve structural strength and minimize thermal bridging
Image
Image
Spray foam insulation is installed in open wall cavities to air seal and insulate
Image
Spray foam provides a critical seal between the subfloor, rim joist, and sill plate
Image
Standard roof trusses are narrow at the eaves, preventing full insulation coverage over the top plate of the exterior walls
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
The air tightness of the garage-to-house air barrier can be tested with a blower door kit and two manometers
Image
The attic kneewall and the open floor cavities under kneewall are both sealed and insulated in one step with spray foam insulation
Image
The back dam of the window sill will force water out
Image
The floor cavities under this attic kneewall are completely open to the unconditioned attic space and a prime target for wind washing
Image
The ICF consists of foam forms that are held in place with plastic or metal spacers and reinforced with metal rebar
Image
Image
The individual exhaust systems for each dwelling unit in this multifamily building result in large numbers of penetrations in the exterior façade
Image
The soffit dam and baffle allow air to flow through the vents without disturbing the insulation covering the top plates
Image
The thermal boundary for a gable roof can be located at either a) the flat ceiling with a vented attic or b) the roof line for an unvented attic
Image
Image
The wall behind the fireplace is an exterior wall and requires a thermal barrier that is continuous with the rest of the wall’s insulation
Image
Thermal bridging is eliminated at the rim joist with the use of joist ledgers that are anchored in the wall
Image
Thermally isolate heated garages in multifamily buildings from ambient space, and thermally isolate all garages in multifamily buildings from interior occupied space. This parking garage is thermally isolated from space above with spray foam insulation.
Image
This assembly can be used to thermally isolate heated or partially heated garages with slab foundations from the exterior in multifamily row houses/townhouses in IECC Climate Zones 3 and higher.
Image
This assembly for above-grade and below-grade garage walls in any climate zone uses continuous rigid insulation along the interior of the wall.
Image
This assembly for above-grade or below-grade garage walls in any climate zone uses a hybrid of continuous rigid insulation and cavity insulation on the interior side of the wall.
Image
This foundation/floor/SIP wall detail shows recommended support of SIP wall panel at the sill plate
Image
This heated garage plenum is insulated along the bottom and sides, and the insulation is fully aligned with an air barrier. The insulation at the bottom of the plenum space meets IECC insulation requirements.
Image
This heated garage plenum space is insulated along its top, bottom and sides, and the insulation at the top of the plenum meets IECC requirements. The insulation along the top and sides is fully aligned with an air barrier.
Image
This HRV, installed in a conditioned attic, provides balanced ventilation to the whole home
Image
This kneewall has no top plate and the resulting gap provides a wide-open pathway for air and vapor to travel between the living space and the attic
Image
This technique for installing electrical wiring avoids the need to cut into the SIP panel
Image
This wall assembly for above-grade garage walls uses cavity insulation and should only be used in IECC Climate Zones 4 or lower due to the risk of condensation on the interior surface of the concrete wall.
Image
Three common ICF wall systems: the flat wall, the waffle wall, and the post-and-beam wall
Image
Two layers of high-permeability house wrap are installed to provide a drainage layer between the SIPS and the homes external cladding
Image
Two layers of XPS are installed with staggered seams over a liquid-applied membrane on the structural sheathing
Image
Typical installation of a double section modular home on a pier and ground anchor foundation
Image
Unfaced fiberglass batt insulation is installed to completely fill the wall cavities and is sliced to fit around wiring, piping, and other obstructions in the wall cavities
Image
Use a smoke pencil to check for air leaks at SIP panel seams, especially along the ridge beam
Image
Image
Image
Use flashing tape to seal around any pipes or vents that penetrate through the foam
Image
Utilities are commonly recessed into cutouts in the foam after concrete has been poured
Image
Image
Walls are being assembled at this SIP house
Image
Image
Image
Whole house fans draw cool night-time air in through open windows and expel hot house air into the vented attic
Image
Window and door rough openings in the ICF wall are surrounded with pressure-treated wood

Image
Wrong - House wrap tape is not fully adhered at seam and flashing tape is missing from window head, jamb, and corner above window.
Image
Wrong - Lack of a weather-resistant barrier allowed water to get behind the siding and rot the framing in this corner rim joist area.
Image
Image
Wrong - Nailing pattern on roof underlayment is erratic and excessive, house wrap should overlap seam, metal step flashing will need to be installed at roof-wall junction.
Image
Wrong - No air barrier is present between the dropped ceiling/soffit and the attic.
Image
Wrong - No air barrier is present between the dropped ceiling/soffit and the attic.
Image
Wrong - No air barrier is present between the floor system and unconditioned space.
Image
Image
Wrong - No air barrier is present in the floor joists spanning over the garage and conditioned space of the home.
Image
Image
Wrong - Stucco has rotted and cracked above a window because of water damage due to lack of proper flashing and drainage.
Image
Image
Image
Wrong - Tape is not well adhered to house wrap and wiring penetration is not sealed.
Image
Wrong - The air barrier is not sealed (picture taken from garage looking into house).
Image
Wrong - The band joist above this garage-house shared wall is not properly sealed.
Image
Wrong - The caulk is too far from the sill plate to effectively air-seal the gap.
Image
Image
Wrong - The rigid foam that was installed as an air barrier at the rim joist was not properly air-sealed.
Image
Image
Image
Wrong - This IR image is showing that cold air is entering the home at the window frame and the sill plate at the base of the wall.
Image
Wrong - This IR image of a second-floor landing shows that attic air is flowing far into the interstitial floor cavity of the second-floor landing
