STACBOND® A2 is a non-combustible composite panel composed of two aluminium sheets and a mineral core developed to meet the highest fire classification standards.

Thanks to its exceptional mechanical properties: high rigidity, excellent flatness, impact resistance, durability and ease of maintenance together with a reaction to fire classification A2-s1, d0 (according to UNE EN 13501-1:2007), make it the ideal cladding solution for high-rise and high-occupancy buildings.

It complies with the strictest fire classification requirements, among which the following stand out:

 UNE EN 13501-1:2007 – A2-s1, d0

 NFPA 285 – PASS

 ASTM E84 – A CLASS
