Zusammenfassung:	FIELD: building industry. SUBSTANCE: in laminated heat-insulating product which comprises fireproof reinforcing layer and heat-insulating layer, raw mix for fireproof reinforcing layer comprises, wt %: high-temperature fiber, 45-54.7; refractory clay, 35- 49.6; polyvinyl acetate dispersion, 3-5; polyacrylamide, 0.3-0.4, and raw mix for heat-insulating layer comprises, wt %: high-temperature fiber, 56-65; refractory clay, 30- 34.8; polyvinyl acetate dispersion, 6-9; polyacrylamide, 0.1-0.2. Method comprises manufacturing raw mixes as fibrous suspension at liquid solid ratio from 3:2 to 8:3 for heat-insulating layer and at liquid solid ratio from 10:3 to 14:3 for fireproof reinforcing layer, molding the product in layers and heat treating it. Heat-insulating layer is first molded at 0.01-0.05 MPa and fireproof reinforcing layer is then molded. EFFECT: higher service properties of the products and improved quality of surface thereof.
