A bearing wall is specifically defined as a wall that supports additional vertical loads, meaning it is integral to the structural integrity of a building. These walls carry weight from elements above, such as beams, floors, or roofs, and transfer it down to the foundation. Bearing walls are crucial in maintaining the stability of a structure and are typically made from materials that can withstand significant loads, such as masonry, concrete, or heavy timber.

In contrast, the other types of walls mentioned serve different purposes. For instance, moisture protection is typically the function of waterproof walls or membranes. Insulation walls are designated for thermal efficiency rather than load-bearing roles. Non-structural walls, on the other hand, do not carry any vertical loads and are primarily used for room divisions, aesthetics, or other non-load-bearing purposes. This distinction highlights the essential role that bearing walls play in construction and structural engineering.
