Failure of Roof Structure from Pressurization Due to Window Failure During a Hurricane.
Fill in the hole left by the missing top plate with a rigid air blocking material or rolled batt insulation that is spray foamed in place
Flood damage-resistant materials include concrete and tile flooring, metal cabinets and doors, and glass-block windows.
Floor cavity air pressure is measured by placing a tube into the floor cavity through a small drilled hole
Floor cavity pressure is measured by inserting a tube into the floor cavity using an extension pole
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
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
Gaps at shared common walls can be a significant source of air leakage in multi-family buildings
Heated or partially heated garages with podium decks should be thermally isolated from both ambient exterior space and interior conditioned space by insulating the interior of the garage walls and ceiling and extending the insulation below grade.
Heated recirculation plenum spaces can be installed in parking garages in cold climates to prevent pipes from freezing and warm the floor of occupied space directly above the garage.
ICFs provide continuous wall insulation from the roof to the footing with very little thermal bridging
Identify what materials will constitute the continuous air barrier around the building envelope.
If water rises above the foundation and enters the wall cavity it will not damage the moisture-resistant closed-cell foam or exterior extruded polystyrene, while gaps in the paperless drywall allow airflow of easy removal of panels for drying and cleaning
In cathedral ceilings, parallel chord trusses allow thicker insulation levels over the exterior wall top plates.
Infrared imaging shows cold conditioned air pouring out of the open floor cavities under this attic kneewall into the hot unconditioned attic
Infrared thermography during depressurization testing reveals air leakage at corner of spray foam-insulated room where wood-to-wood seams in framing were not air sealed
Install a continuous air barrier below or above ceiling insulation and install wind baffles.
Install a foam gasket along top plates before installing drywall
Install a housewrap drainage plane between the SIP panels and the exterior cladding
Install a rigid air barrier to separate the porch attic from the conditioned space.
Install an ENERGY STAR labeled insulated door with an automatic closer. Weather strip the door frame
Install continuous rigid foam insulation or insulated siding to help reduce thermal bridging through wood- or metal-framed exterior walls.
Install continuous top plates or blocking at the tops of walls adjacent to conditioned space to minimize air leakage.
Install insulation under platforms constructed in the attic for storage or equipment.
Install wood framing cross pieces in the attic rafter bays on each side of the duct chase
Install wood framing cross pieces in the attic rafter bays on each side of the duct chase
Insulating both exterior and garage-side faces of plaza deck can reduce thermal bridging. If garage is heated or partially heated, hybrid spray foam/batt insulation on garage side of plaza deck should extend to the perimeter of the garage.
Insulating the exterior and garage-side faces of the garage plaza deck can reduce thermal bridging. If the garage is heated or partially heated, the spray foam on the garage side of the plaza deck should extend to perimeter of garage.
