A building member (1) comprises a load bearing element (4, 6) comprising a strip of compressed mineral wool having a density of at least 50 kg/m<3>. The load bearing elements may form a frame element of a wall panel which further comprises a central insulating zone (9) of relatively less compressed mineral fibre, facing layers of sheet material and (2, 3) extending across the surface of the panel and sandwiching the mineral fibre load bearing element. The facing layers are bonded to the load bearing elements, and, if desired, the insulation in the central zone, using bonding agent which cures whilst the sandwich of materials is subjected to compression, for instance whilst being vibrated. |
