A utility vent is a type of ventilation component commonly found on the exterior of buildings, usually on the roof or walls. It is designed to allow air to flow in and out of the building, serving as an essential part of the building's ventilation system. The primary function of a utility vent is to allow for the exchange of air between the interior and exterior of the building. This helps to maintain a healthy indoor environment by removing stale air and replacing it with fresh air. In addition, utility vents can help to regulate temperature and humidity levels, improving the overall comfort of the building's occupants.
