Assembly can be used in IECC CZ 3 and above to thermally isolate garages in multifamily row houses with slab foundations. For unheated garages, it is unnecessary to insulate wall between garage and exterior of slab or slab underneath garage.
Drop-in ceiling assemblies consisting of suspended ceiling tiles (common in multifamily buildings) are often insulated with fiberglass or mineral wool batt insulation.
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.
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.
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.
Plan view (from above) showing how the existing garage wall gypsum board is cut away to air-seal the shared wall before adding rigid foam insulation on the garage and exterior walls of the home.
Right - Fiberglass/mineral wool insulation thermally isolates the garage from the interior occupied space above.
Right - The ceiling above the garage is insulated and air-sealed with open-cell spray foam to keep garage fumes out of the living space above.
Right - This heated garage plenum is insulated along the bottom of the plenum space.
Right - This heated garage plenum is insulated and has an opening to access the interior, allowing for repairs and maintenance.
Right – Spray foam insulates the walls and ceilings separating the garage from the home.
Rigid foam insulating sheathing installed over an existing garage ceiling with retrofits to air seal exterior wall before adding exterior wall insulating sheathing
Rigid foam insulating sheathing is installed on existing garage ceiling and covered with a new gypsum board fire protection layer installed over the foam.
Rigid foam insulation is installed on the garage side of the shared garage wall and roof of an existing home
Rigid insulation and air-sealing can be used to thermally isolate garages from interior occupied space in multifamily row houses/townhouses.
Rigid insulation can be used as a thermal break between a garage slab with a heated plenum space and a separately cast garage slab without a heated plenum space.
Side view showing air-sealing and rigid foam insulation is installed over existing wall and ceiling under a room above, then covered with new gypsum board.
Side view showing how the existing garage wall and ceiling are air-sealed prior to installing rigid foam insulation on the garage side of the shared wall of an existing home.
The original corner seam is air-sealed with caulk, then rigid foam is installed on the existing garage ceiling and walls, and finally covered with drywall.
Thermally isolate heated garages in multifamily buildings from ambient space, and thermally isolate all garages in multifamily buildings from interior occupied space. This parking garage is thermally isolated from space above with spray foam insulation.
This assembly can be used to thermally isolate heated or partially heated garages with slab foundations from the exterior in multifamily row houses/townhouses in IECC Climate Zones 3 and higher.
This assembly for above-grade and below-grade garage walls in any climate zone uses continuous rigid insulation along the interior of the wall.
This assembly for above-grade or below-grade garage walls in any climate zone uses a hybrid of continuous rigid insulation and cavity insulation on the interior side of the wall.
This heated garage plenum is insulated along the bottom and sides, and the insulation is fully aligned with an air barrier. The insulation at the bottom of the plenum space meets IECC insulation requirements.
This heated garage plenum space is insulated along its top, bottom and sides, and the insulation at the top of the plenum meets IECC requirements. The insulation along the top and sides is fully aligned with an air barrier.
This hot climate zone home uses high quality batt insulation between studs to insulate this connecting garage wall.
This wall assembly for above-grade garage walls uses cavity insulation and should only be used in IECC Climate Zones 4 or lower due to the risk of condensation on the interior surface of the concrete wall.
To ensure a complete air barrier between the garage and the house, the wall between the garage and the house was insulated and air-sealed with four inches of high-density spray foam.
