The invention relates to thermally insulating materials. It refers to a thermally insulating slab consisting of entangled refractory fibres, the major portion of the fibres being substantially parallel with the main faces of the slab, characterized in that the back of the slab bears a plurality of furrows or grooves distributed over the back. The slab is used for the insulation of furnaces and the like.

Thermally insulating slabs made of refractory fibers for the insulation

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. This slab is useful for insulating the inner surfaces of furnaces.
