Fire Safety on External Façades: Why Are A2 Class Composite Panels Mandatory?

Fire Safety on External Façades: Why Are A2 Class Composite Panels Mandatory?

In modern architecture, composite panel cladding has earned an indispensable place thanks to its lightness and the richness of form it offers. However, when choosing a façade material, structural strength and fire performance are as decisive as visual appeal. Panels with a B1 or B2 class combustible core, especially those used in multi-storey buildings, pave the way for flames to spread rapidly between floors in the event of a fire. Mineral-filled aluminium composite panels in the A2 non-combustibility class, on the other hand, do not drip when exposed to heat, limit the release of toxic gases and delay the spread of fire. Choosing the right material in your projects is not just a regulatory requirement but an investment that directly safeguards the life of the building and the safety of its users.
