Natural Ventilation

Consider natural ventilation to create a cooler and more comfortable building with no operating costs or energy consumption. Natural ventilation is the evacuation of hot air and fumes directly through an opening in the ceiling. The opening is covered by a weatherproof ventilator, and air-flow is supported by fresh intake air at the floor level. We have several ventilator varieties and can help you select the best fit for your space.
