ABSTRACT:
A method of manufacturing a building product from a mix (6) including particulate material and a thermoplastic binder which comprises heating the mix at least to a temperature at which the thermoplastic binder in the mix liquefies, subjecting the heated thermoplastic mix to a pressing action that shapes the heated mix, and cooling the shaped heated thermoplastic mix to solidify the thermoplastic binder and form the product (FIG.4).
