Abstract: The invention relates to a heat-insulating slab formed by a plurality of continuous strips maintained in assembly side by side, each strip comprising entangled refractory fibres the major portion of which is perpendicular to the two main faces of the slab, the strips being maintained in assembly exclusively by means of a plurality of lines, ribbons or cords of an organic synthetic matter which adhere to the strips and are applied to the two main faces of the slab perpendicular to the strips.
