Insulating the exterior and garage-side faces of the plaza deck can reduce thermal bridging. If the garage is heated or partially heated, the faced batt insulation on the garage side of the plaza deck should extend to perimeter of garage.
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
Light tubes adjacent to unconditioned space include lens separating unconditioned and conditioned space and are fully gasketed
Limited attic access can make inspections for missing air barriers and insulation challenging
Limited attic access may make it necessary to use a bore scope when inspecting for missing air barriers and insulation in existing buildings.
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
Marriage joints between modular home modules at all exterior boundary conditions fully sealed with gasket and foam
Peel-and-stick panel tape provides added assurance that SIP panel seams will remain airtight
Pressure manometers are used to determine the level of pressurization and rate of leakage when conducting blower door testing and building diagnostics
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
