Image
Right – Rigid air barrier installed between double-wall assembly. Inside cavity will be insulated
Image
Image
Right – Structural insulated sheathing can provide racking strength (lateral load resistance), and serve as an air barrier and thermal barrier if installed according to manufacturer’s specifications with taped, sealed seams
Image
Right – This attic knee wall and the floor joist cavity openings beneath it are being sealed and insulated with spray foam.

Image
Image
Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Image
Rigid foam insulated sheathing placed exterior to house wrap, interior to house wrap, or take the place of the house wrap
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.
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
Special molded corners provide continuous insulation layer at the corners to improve structural strength and minimize thermal bridging
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
Thermal bridging is eliminated at the rim joist with the use of joist ledgers that are anchored in the wall
Image
This foundation/floor/SIP wall detail shows recommended support of SIP wall panel at the sill plate
Image
This technique for installing electrical wiring avoids the need to cut into the SIP panel
Image
This wall and window assembly has excessive framing around the windows, which can lead to heat gain in how climate zones.
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
Use a smoke pencil to check for air leaks at SIP panel seams, especially along the ridge beam
Image
Use a truss joist header assembly as shown here to reduce thermal bridging in hot climate zones.
Image
Use flashing tape to seal around any pipes or vents that penetrate through the foam
Image
Image
Utilities are commonly recessed into cutouts in the foam after concrete has been poured
Image
Walls are being assembled at this SIP house
Image
Window and door rough openings in the ICF wall are surrounded with pressure-treated wood
Image
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
Image
Wrong - This IR image shows where hot attic air has penetrated into the floor cavity that lies behind the stairwell wall
Image
Wrong – A visible gap in the insulated sheathing introduces unwanted outside air, creating a thermal bypass and encouraging convective air flow
Image
Wrong – Conventional T-post detail is extremely difficult to insulate and usually doesn't happen
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
Image
Image
Image
Image
Image
Image
Wrong – If the insulated sheathing will serve as an air barrier and drainage plane, any cuts and seams must be taped or sealed.
Image
Image
Wrong – No air barrier installed between the walls and a larger gap between the walls that needs sealing
