For what purpose are grouted airspaces in wall coverings used?

Grouted airspaces in wall coverings serve the important purpose of acting as a controlled space that can accommodate moisture management and ventilation requirements effectively. While grouted airspaces may create the appearance of being an alternative to the required airspace, their primary function is to facilitate drainage and ventilation to prevent moisture buildup behind the wall covering. In this context, they are not merely an aesthetic feature or a primary source of insulation. Instead, they fulfill a specific role in helping to manage environmental factors that could negatively impact the integrity of the wall and the structures associated with it.
