STACBOND® A2
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 as well as a fire classification A2-s1, d0 (according to UNE EN 13501-1:2007) make it the ideal solution for high-rise buildings with high occupancy.
 It meets the strictest fire classification requirements, including the following:
 UNE EN 13501-1:2007 – A2-s1, d0
 NFPA 285 – PASS
 ASTM E84 – CLASS A
