A structural spline made of a solid 2x is used where needed to meet structural load requirements at SIP panel seams
Image
A surface spline reduces thermal bridging much more than a structural spline at SIP panel seams
Image
Advanced framing details include corners that are constructed with fewer studs or studs aligned so that insulation can be installed in the corner.
Image
Advanced framing details include framing aligned to allow for insulation at interior-exterior wall intersections.

An all-terrain forklift is used to move and stage the panels
Image
An insulated spline is another option for avoiding thermal bridging at SIP panel seams
Image
Image
Closed-cell spray foam insulation is added to the wall cavities of an existing exterior wall
Image
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.
Image
Construct exterior walls with structural insulated panels (SIPs) to provide an airtight wall with consistent insulation and very little thermal bridging.

Image
Image
Image
Expanded polystyrene insulation is installed with joints taped and lath attached in preparation for the application of stucco
Image
Exterior fiberglass insulation on this new home was (incorrectly) cut to terminate below-grade after backfill, which will expose the above-grade portions of the foundation wall to cold temperatures
Image
Exterior XPS basement insulation is correctly installed to completely cover the foundation wall
Image
Image
Floor cavity air pressure is measured by placing a tube into the floor cavity through a small drilled hole
Image
Floor cavity pressure is measured by inserting a tube into the floor cavity using an extension pole
Image
Foil-faced rigid foam and spray foam can be used to insulate a basement on the interior; use good moisture management techniques to keep the basement dry
Image
Image
Image
Gaps at shared common walls can be a significant source of air leakage in multi-family buildings

Install wood framing cross pieces in the attic rafter bays on each side of the duct chase
Image
Image
Lay out the rigid foam sheathing joints so they do not align with the window and door edges
Image
Lifting plates attached to the wall provide good bracing to tighten up SIP panel seams
Image
Limited attic access can make inspections for missing air barriers and insulation challenging
Image
Limited attic access may make it necessary to use a bore scope when inspecting for missing air barriers and insulation in existing buildings.
Image
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
Image
Image
Peel-and-stick panel tape provides added assurance that SIP panel seams will remain airtight
Image
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
