What are studwall cavities commonly used for in construction?

Studwall cavities are primarily utilized in construction for various essential functions, but one of their most common purposes is as air plenums for ventilation systems. The configuration of stud walls allows for the integration of ductwork or space for air movement, enabling efficient distribution of conditioned air throughout a building.

In this context, the stud cavity can serve as a pathway for air to travel from air handling units to different parts of the structure, ensuring that the indoor environment remains comfortable and well-ventilated. This characteristic is crucial for maintaining air quality and temperature control within commercial spaces.

While stud cavity spaces can also accommodate other uses, like electrical wiring and insulation placement, these are not their primary function in many design scenarios. In contrast to air plenums, storage areas for tools are not typically a standard application for stud walls, as they are designed more for functional building systems rather than for storage purposes. Thus, the role of studwall cavities as air plenums for ventilation aligns closely with their intended purpose in construction, making it the most appropriate answer.
