Raybond A2

RAYBOND® A2 is a first choice for maximum fire safety, it is a fire-retardant ACP composed of aluminium skins and 90% mineral filled fire-retardant core. It meets the very high requirements of fire class A2 – s1, d0 and is approved by the building authorities.

Due to its non-combustible core RAYBOND® A2 meets the high requirements of the fire regulations and enhances the possibilities for the concept and design of buildings.

RAYBOND® A2, as indeed all the products of the RAYBOND® family, allows simple processing, is impact-resistant, break-proof and weatherproof and, above all, non-combustible.
