The DB SI in its section concerning external propagation, indicates that in order to limitate the risk of vertical propagation through the façade between two fire sectors, between a particularly high risk area and other higher zones
in the building, or towards a protected staircase or protected corridor, this façade shall be at least EI-60 in a belt with height of not less than 1 metre.
Catastrophes affecting high-rises have shown the importance of protecting and anchoring joints between both slabs and facades. Otherwise, existing holes between curtain walls and light facades can work as true chimneys in case of fire causing flames and smoke to get out of control propagating into higher areas in the building, and thus hampering an orderly evacuation procedure.
The manifold and various configurations of facades make it difficult to decide on the most appropriate protection. Therefore, do not hesitate to contact our Sales Department for assistance.
