LOGO-NÚCLEO-A2

STACBOND® A2 is a non-combustible composite panel composed of two aluminum 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 – A2-s1, d0

  NFPA 285 – PASS

  ASTM E84 – A CLASS

  MSZ 14800-6:2020 – PASS
