Stac Bond A2
STACBOND® A2 is a non-combustible composite panel made up of two aluminum sheets and a mineral core developed to meet the highest fire classification regulatory requirements.
Thanks to its exceptional mechanical properties: high rigidity, excellent flatness, impact resistance, durability and ease of maintenance together with an A2-s1, d0 reaction to fire classification (according to UNE EN 13501-1:2007), make it the ideal cladding solution for high-rise buildings and high-occupancy buildings.
It complies with the strictest fire classification requirements, among which are:
UNE EN 13501-1:2007 – A2-s1, d0NFPA 285 – PASS
ASTM E84 – CLASS A
