摘要： A method of manufacturing sheet form insulation products from an aqueous slurry containing calcium silicate comprises the steps of pumping the slurry into a closed mould cavity in a platen filter press, at least one wall of the mould cavity being foraminous to an extent sufficient to allow the escape substantially only of fluid, stopping the pumping at a predetermined level of back pressure in the mould cavity, followed by closing the press to reduce at least one dimension of the mould cavity a prechosen amount.
