ABSTRACT:
A panel of microporous thermal insulation which comprises an envelope of glass fibre cloth which surrounds and is bonded to a block of microporous thermal insulation is manufactured by heating the glass fibre cloth so as to drive off organic material, applying a silane in an acidic solution to the cloth, drying the cloth in order to produce cross-linking of the silane so as to cause the cloth to stiffen, and applying to the cloth an aqueous suspension of particulate silica, an aqueous solution of sodium silicate or potassium silicate, or a cellulose solution. Microporous thermal insulation is introduced into a bag mode from the cloth and the bag is then compressed to consolidate the insulating material and to produce a bond between the insulating material and the bag.
