Improvements introduced in the object of the principal patent No. P 9602344 (9) "process for the manufacture of sound-absorbing and flame plates for surface coatings and plate obtained by the practice of the procedure." They comprise subjecting to the plates in the manufacturing process and prior to solidification of the material to a pressing operation in a press machine to obtain an optimum compactness and flatness. The granulated material can be used tipoligero as the Arlite. The assembly of the plates against the surfaces to be coated is performed by a structure battens, such as profiles of U-section or omega previously attached to the surface concerned and that, in turn, hold the plates by gluing or screwing the same for the next to its edge areas. Between the coated surfaces, the strips and the plates air chambers, of insulating and capable also be filled by properties of absorbent materials of porous structure and / or fibrous defined. Applicable to enhanced absorbent and flame retardant properties of the manufactured boards.
