In the event of a fire, natural smoke and heat exhaust ventilation systems are used to evacuate the hot gases produced during the development of a fire whilst simultaneously creating a smoke-free layer above the ground by removing the smoke.
Their use to create these smoke-free zones by gravity is widespread, as it has been clearly demonstrated that these systems are effective at :
reducing the damage caused by fires and financial losses by preventing smoke damage
facilitating access for firefighters by improving visibility
reducing roof temperature and delaying the lateral spread of the fire.
To ensure these benefits are obtained, it is essential that the natural smoke and heat exhaust ventilators are in perfect working order, ready for safe use whenever they are needed. Adexsi’s range of security products can be mounted either on roofs or façades or inside the buildings to act as fire stopping solutions.
