RAYBOND®/FR is a fire-retardant ACM composed of aluminum skins and 70% mineral filled fire-retardant core. It passes most countries’ fire safety codes for exterior and interior, EN 13501-1, class B.

Due to its mineral-filled core RAYBOND®/FR meets the higher requirements of the fire classifications. It is hardly inflammable and offers all the proven product properties of the RAYBOND®/FR family, such as flatness, formability, resistance to weather and simple processing.

RAYBOND™ is therefore an ideal material for almost unlimited design possibilities for ventilated façades of any application.
