<p>The reinforcement layer (7) according to the invention, covering at least one face of an insulating board (D) is made of a composite material the matrix of which consists of 25 to 50% of cement, from 30 to 60% mineral fibres, and from 2 to 15% of synthetic resin and from 0 to 2% of various adjuvants, especially cure accelerators, and the reinforcement of which consists of mineral and/or synthetic fibres embedded in the matrix. The jointing between adjacent boards, each comprising such a reinforcement layer, is provided by the addition of a strip of reinforcement and of matrix as a paste into the grooves between adjacent boards. Application to the production of boards for internal and external insulation of facades, of floor-covering boards and of insulating boards for roof supports and with integral internal decoration. <IMAGE></p> |
