The invention consists of a panel comprising an insulating core ( 10 ) and two outer faces ( 2, 3 ) made of metallic sheet and disposed on opposite sides with respect thereto, wherein a cushion ( 12 ) of mineral wool is arranged between one of the outer faces and the insulating core. In this way a panel is obtained which is capable of compensating for the thermal expansion of the sheet metal, especially in the case of fire. |
