ALUCOBOND®A2

Aluminium cover sheet –

ALUCOBOND®A2

ALUCOBOND®A2 is a light and rigid non-combustible sandwich panel with two aluminium cover sheets and a mineral-filled polymer core. The material’s fire classification in accordance with the EN 13501-1 standard is class A2, s1, d0. It offers outstanding processing properties and comes in a wide range of colours. The material has been approved in line with the EN 45545 standard on railway vehicles. We deliver ALUCOBOND®A2 as composite sheets.
