Alucobond

Alucobond A2

Across the world, Alucobond A2 is the only non-combustible aluminum composite panel used in architecture.

Due to its non-combustible core, this fantastic product meets stringent fire regulations and hugely increases the possibilities when it comes to creative building design.

As with all Alucobond products, Alucobond A2 allows for simple processing, is impact-resistant, break-proof, and weatherproof – and above all non-combustible.
