What is a cupola vent primarily used for?

A cupola vent is primarily designed for ventilating spaces such as barns and homes. Its functionality revolves around promoting air circulation, which helps manage temperature and humidity levels within the structure. By allowing warm air to escape from the top of the building while drawing in cooler air from lower openings, cupola vents assist in maintaining a comfortable environment.

In the context of barns, this is especially important for the health of animals and the preservation of stored goods, as excess heat and moisture can lead to unfavorable conditions. Although cupolas can also serve aesthetic purposes and provide natural light, their primary role is centered around effective ventilation, making this choice the most accurate.
