ALUCOBOND® A2

ALUCOBOND plus

ALUCOBOND® A2 is the first non-combustible aluminium composite panel used in architecture that fulfils the respective standards worldwide.

Thanks to its mineral core, ALUCOBOND® A2 meets the strict requirements of some
of the toughest fire regulations while retaining the possibilities for the concept and design of buildings. ALUCOBOND® A2, just like all the products of the ALUCOBOND® family, allows simple processing, is impact-resistant, breakproof and weatherproof
and, above all, non-combustible.
