Stationary vents are a type of ventilation system commonly used in buildings to provide natural air circulation and prevent the buildup of moisture and odors. These vents are typically installed on the roof or upper portion of a building and are designed to allow air to enter and exit the structure. Stationary vents come in a variety of shapes and sizes, including ridge vents, turbine vents, and soffit vents. Ridge vents are installed along the peak of a roof and allow warm air to escape, while soffit vents are installed under the eaves of a roof and allow fresh air to enter the attic space. Turbine vents, on the other hand, use wind power to draw air out of the building.
