The function of an EFC is to create, in the event of a fire, an opening on the roof, or on the wall, to allow the evacuation of the combustion products (heat and smoke), from the inside of the building to the external environment.

The EFC creates a smoke-free lower zone that preserves people's health, facilitates their evacuation and promotes rescue and extinguishing interventions.

Aersmoke EFC is manufactured in compliance with directive 89/106 / EC ("Construction Products" Directive) and CE marked in accordance with the harmonized standard EN12101-2.
