The invention relates to a laminated material reflecting the thermal radiations and which is flameproof and is also a thermal insulator, designed for the production of antithermal equipment and shields, and to a process for producing the same The laminated material comprises a textile base made of a fabric, a knitted or a non-woven textile of polyacrylnitrile fibres, thermally stabilized in a known manner, and a polyethyleneterephtalate sheet having a thickness ranging from 6 to 8 microm aluminized on one or both sides, and glued onto the textile base by means of a polychloroprene adhesive film, fireproofed with antimony bloom For a non-stop production with pressure rollers, the process consists in coating one of the metallized sides of the polyethyleneterephtalate sheet with a solution of adhesive in ethyl-acetate having in composition 8 to 12% polychloroprene rubber and 08 to 1 % antimony bloom as a continuous film with a thickness ranging between 02 to 03 mm, followed by the evaporation of the solvent in a ratio ranging from 80 to 95% and pressing the sheet onto the textile base with a pressure of 6 to 12 Mpa and for discontinuous production the sheet is pressed by a piece with cups, heated at a temperature of 40 to 100‹ C for 05 to 2 seconds and at a pressure of 5 to 20 Mpa
