[Prevention] How can the risk of fire from aluminium composite panels be prevented?

Major fires involving aluminium panels have occurred in high-rise buildings around the world. These fires have involved facade fires, spreading rapidly and impacting many floors.


The aluminium composite panel is part of a more general classification of building materials called sandwich panels. These panels are usually installed on the exterior of buildings with hooks / brackets, creating an air space or cavity between the panels and the exterior wall.


If a fire starts in the combustible insulation, it will tend to melt and drip, causing the fire to spread vertically. As the insulation burns, it produces dense, toxic fumes. The open, continuous air cavity allows the fire to spread vertically very quickly outside the building.

Verlingue recommendations


1 – Use aluminium composite panels with non-combustible insulation (glass wool, rock wool), such as materials qualified in Euroclass A1 or A2


2 – If combustible insulation must be used, the panels must be listed / approved with one of the following Factory Mutual (FM) Approved Class I…
