List of featured suppliers of ROOF VENTILATORS Void System on Building Products Index
Roof ventilators and void systems are designed to facilitate air flow in a building by allowing fresh air to enter and hot, stale air to escape. These systems are installed on the roof of the building and work by creating a natural draft, which is driven by the difference in temperature and pressure between the inside and outside of the building. Typically, roof ventilators and void systems are installed in attics, crawl spaces, or other areas of the building where there is limited natural ventilation. They are often used in conjunction with other ventilation systems, such as ductwork or fans, to ensure that the building is properly ventilated.
