Industrial Grade Roof Ventilator constitutes a system of noiselessly passing the outside air to the roof and attic space. The Ventilator has the feature that increasing temperature, heats up the air which rises to the highest point of the roof and passes through the gaps in between ventilator blades naturally drawing cool outside air to replace the air that has just left, allowing efficient air-flow. The Ventilator can be installed with minimum interference to the existing roof structure. The Industrial Grade Roof Ventilator can be supported by the colours and textures to match your roof.
