The panels are surrounded by a frame comprising metal sections in a U section of limbs (10,11,12) and cross pieces (13,14). At the central stop, a strip (23) at right angles to the cross piece includes a cavity (26) produced by forming a metal strip (24). Pref. the limbs (11,12) also include a cavity (27) produced from an elongated strip (24,25), all cavities being filled with a fire protection agent (34) providing cooling under the action of heat. A silicone layer is pref. inserted between the two limbs and the edge faces the fire protection panel.
