FIELD: building materials industry, more particularly manufacture of heat-insulating materials. SUBSTANCE: method comprises preparing industrial foam, adding lime additive thereto in amount of 5- 10% of weight of aqueous solution of foaming agent and calcium chloride additive in amount of 1.5-2% of weight of cement and subsequently mixed dry mixture of cement and wood filling agent. EFFECT: greater resistance of foam and improved adhesion of cement stone and wood filling agent. 1 tbl
