Natural Ventilation

Natural Ventilation

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. This creates a cooler and more comfortable building with no operating costs or energy consumption.


The MoffittVent™ is one of the most effective and efficient natural ventilation device on the market today. It is capable of exhausting large volumes of warm air from a building without letting any rain enter the building.


The Labyrinth Natural Ventilator uses aerodynamically designed baffles and louvers to provide persistent and consistent weatherproof ventilation. The Labyrinth name is trademark of Colt International Licensing Limited, UK


The Ridgepac natural ventilator is designed to be highly efficient, aesthetically pleasing, and a good value with low-cost per CFM.


The Thermoflow® low-profile ventilator is very effective at evacuating large amounts of warm air and smoke. It has been designed to provide superior air-flow capacity levels and simplified installation, while still providing minimal roof load and wind load.

GreenRoo™ Turbine Vent

Made of marine grade, light gauge aluminum, the GreenRoo™ turbine vent spins easily in the wind. This offers air movement at a greater volume and rate. Its light weight means there is little wind load on the roof, leading to easier building construction and making expensive support steel unnecessary. The GreenRoo™ is a big improvement over the old "onion" turbine vents.
