This specification discloses a light-weight building panel, a building system incorporating the panels and the process of making them. The process includes a cementitious material in the form of a fibre-reinforced cellular cementitious material which weighs substantially less than regular concrete. Light-weight metal structural members are partially embedded in the cementitious material during the manufacturing of the panel and portions of the members project therefrom. One embodiment has exposed "C"-shaped channel members that provide, in a wall or floor panel, structural surfaces such as studs or beams ready in place to receive finishing surfaces such as plaster board or dry- wall sheets. It also provides recessed wall areas for installation of electr ic boxes and the like.
