<p>A method of making a finished product such as a building board includes the steps of providing a feedstock of polystyrene particles and lignocellulosic material in finely divided particle or fibre form, and mixing the feedstock with a thermosetting resin. This product is then subjected to suitable conditions of temperature and pressure to cause the polystyrene to melt and to cause the thermosetting resin to set and then cooling to form the finished product.</p> |
