Abstract
A structural panel includes a core and first and second facing sheets. The core has bonding surfaces on first and second, opposite sides thereof. The first facing sheet is a non-thermoplastic, fire retardant facing sheet having an inner surface bonded to the bonding surface on the first side. The second facing sheet is bonded to the bonding surface on the second side. The first facing sheet is fire retardant or non-flammable and the core is at least fire retardant. The structural panel finds particular utility as a building-cladding panel.
