A crane is used to install the SIP fireplace chimney chase
A pumper is used to place the concrete into the foam form walls
A standard site-built roof of rafters may pinch the insulation at the eaves
A structural spline made of a solid 2x is used where needed to meet structural load requirements at SIP panel seams
A surface spline reduces thermal bridging much more than a structural spline at SIP panel seams
Advanced framing details include corners that are constructed with fewer studs or studs aligned so that insulation can be installed in the corner.
Advanced framing details include framing aligned to allow for insulation at interior-exterior wall intersections.
Advanced framing details include insulated headers over windows and doors.
Advanced framing details include minimal framing at windows and doors.
Advanced framing details include using the minimum amount of wall studs permitted by code.
Advanced framing showing open headers
After installing the house wrap over the SIPS, window flashing is installed
An all-terrain forklift is used to move and stage the panels
An insulated spline is another option for avoiding thermal bridging at SIP panel seams
Construct exterior walls with insulated concrete forms (ICFs) that provide insulation without thermal bridging, as well as air sealing, a drainage plane, and high structural strength.
Construct exterior walls with structural insulated panels (SIPs) to provide an air-tight wall with consistent insulation and very little thermal bridging.
Design the roof with raised heel trusses to allow full insulation over the top plates of the exterior walls.
Different types of ICF blocks
Double-wall framing
For slabs on grade in CZ 4 and higher, 100% of slab edge insulated to ≥ R-5 at the depth specified by the 2009 IECC and aligned with thermal boundary of the walls
ICF forms are filled with the use of a concrete pumper truck
ICFs provide continuous wall insulation from the roof to the footing with very little thermal bridging
In cathedral ceilings, parallel chord trusses allow thicker insulation levels over the exterior wall top plates
In cold climates, install slab edge insulation when pouring slab on grade foundations.
Install a housewrap drainage plane between the SIP panels and the exterior cladding
Install continuous rigid foam insulation or insulated siding to help reduce thermal bridging through wood- or metal-framed exterior walls.
Install insulation under platforms constructed in the attic for storage or equipment.
Install waterproofing on portions of the ICF that will be below grade
Insulated sheathing has been taped and sealed at seams
Lay out the rigid foam sheathing joints so they do not align with the window and door edges
Lifting plates attached to the wall provide good bracing to tighten up SIP panel seams
Make sure the beads of caulk are continuous the full length at each SIP panel seam, such as at the wall-roof seam, to maintain air barrier continuity
Measure the depth of insulation
Monolithic slab with a grade beam
No insulated sheathing seams are visible from the inside during framing
Peel-and-stick panel tape provides added assurance that SIP panel seams will remain airtight
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall

Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Rigid foam insulated sheathing placed exterior to house wrap, interior to house wrap, or take the place of the house wrap
Scaffolding is continually raised as courses of foam brick are added so that that the pour man can see both sides of the wall during the pour
SIP panel walls are less susceptible to air leakage and convection issues than stick-built walls
SIP panels should be stacked high, dry, and flat
Slab independent of foundation wall
Special molded corners provide continuous insulation layer at the corners to improve structural strength and minimize thermal bridging
Standard roof trusses are narrow at the eaves, preventing full insulation coverage over the top plate of the exterior walls
The back dam of the window sill will force water out
The floor cavities under this attic kneewall are completely open to the unconditioned attic space and a prime target for wind washing.
The ICF consists of foam forms that are held in place with plastic or metal spacers and reinforced with metal rebar
The ICF walls of this home are braced to prepare for pouring the concrete
Thermal bridging is eliminated at the rim joist with the use of joist ledgers that are anchored in the wall
This foundation/floor/SIP wall detail shows recommended support of SIP wall panel at the sill plate
This technique for installing electrical wiring avoids the need to cut into the SIP panel
Three common ICF wall systems: the flat wall, the waffle wall, and the post-and-beam wall
Two layers of high-permeability house wrap are installed to provide a drainage layer between the SIPS and the homes external cladding
