A roof vent turbine is a type of ventilator that is used to provide ventilation to a building. It is usually mounted on the roof of a building and is designed to draw air out of the building and exhaust it to the outside. This helps to reduce the amount of heat and moisture that can build up inside the building, which can lead to mold and mildew growth. Roof vent turbines are typically powered by wind, although some models may be powered by electricity. They come in a variety of sizes and shapes, and can be made from different materials such as plastic, metal, or wood. The size and shape of the turbine will depend on the size of the building and the amount of ventilation needed. Roof vent turbines are an important part of a building’s ventilation system, as they help to keep the air inside the building fresh and healthy.
