<p>Hollow brickwork is incorporated in a light material such as agglomerated pumice grit or plastics, pref. polystyrene, between 2 layers of reinforced concrete. Preferably full panels, or panels with openings, are made in jointed profiled moulds. A 3rd layer of reinforced concrete can have a reinforcing grid connected to the others, with a plate of heat-insulator e.g. expanded polystyrene, in its thickness.</p> |
