When a building is on fire the people die from flue gases on their way to the emergency exit. What natural smoke and ventilation systems (NSHEV) are doing is to exhaust toxic gases and by that reducing heat and the amount of smoke in the building. This not only enables people to escape but the firefighters to extinguish fire in a more effective way. There reduction of heat by exhausting flue gases protects the building itself and the people trying to escape and the firefighters as well.


When sensors defecting a fire and report to one of our control panels skylights on the ceiling and windows open immediately to do their job - exhausting smoke and heat.
