The most efficient way of providing natural ventilation to an industrial building would be not to have the roof at al. The hot air generated due to working conditions shape on shop floor would justice and get lost in the atmosphere.
Unfortunately this is not practical, so we provide the next best solution with the GRAVENT industrial ventilation system. You will open up your roof to the sky, but we arrange to keep out the sun and GRAVENTS gives free passage to hot air, smoke, fumes etc. (solid arrows) to leave the building irrespective of weather conditions or wind direction. Outside wind (hollow arrows) blowing any direction, always helps extract inside air, Greater Rain, no matter how heavy, drains out on the outside of the roof sheets. Not even a drop comes in, yet there is no obstruction for the exhaust of hot air.
