Smoke Ventilation

Smoke and heat exhaust ventilation systems, also known as “SHEVS” are natural or powered systems to remove smoke from a building allowing low level escape routes to be kept clear of smoke and reducing damage to the building. The purpose of smoke and heat exhaust ventilation systems (SHEVS) is to lead smoke and heat out of a burning building, whilst keeping escape corridors and stairs free of smoke for the safe and secure escape of the buildings occupants.
