Cavities in Architecture

Cavities are essential elements in architecture, providing space for light, air, and natural cooling or heating. In a building, cavities can be found in walls, ceilings, and floors, and they often serve as insulation from external elements.

Cavities can also be used for storage or mechanical systems such as air conditioning or heating equipment. In addition, they can be used for aesthetic purposes, such as to create interesting patterns or shapes that add to the overall design of a building.

However, cavities can also pose challenges during construction and maintenance, as they can become sources of moisture or air infiltration, leading to mold growth or deterioration of building materials. Therefore, it is important to ensure that cavities are properly sealed and insulated to ensure their long-term functionality and durability.
