This hot climate zone home uses high quality batt insulation between studs to insulate this connecting garage wall.

Image

This assembly for above-grade and below-grade garage walls in any climate zone uses continuous rigid insulation along the interior of the wall.

Image

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.

Image

Rigid insulation and air-sealing can be used to thermally isolate garages from multifamily row houses/town houses with basement foundations in IECC Climate Zones 3 or higher.

Image

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.

Image

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.

Image

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.
