A process for making fibre reinforced cellular cementious building materials. Firstly, mix separately a foam slurry and a cementious mixture containing water and random glass fibres. Secondly, combine the foam slurry with the cementious mixture in a container to form a cellular cementious slurry containing random glass fibres. The container has a bottom with an orifice positioned adjacent the bottom. Thirdly, pull two parallel spaced layers of integrally formed glass fibre reinforcing mesh through the mixing container filled with cellular cementious slurry and out through the orifice into a drying tray. As the reinforcing mesh passes through the mixing container it pulls along with it cellular cementious slurry. The orifice restricts the amount of cellular cementious slurry that is drawn into the drying tray, thereby serving to gauge the dimensions of the building material. Fourthly leave the cellular cementious slurry to cure in the drying tray until the cellular cementious slurry has set thereby resulting in a cellular cementious building material having two reinforcing layers of integrally formed glass fibre mesh with random glass fibres extending between the two layers of integrally formed glass fibre mesh.
