ABSTRACT:
A method for producing weather-resistant panels of moulded elements consisting of particles, e.g. fibres or chips, mixed with bonding agents, or of raw materials prepared in some other way and pressed together under heat, a layer of vulcanizable elastomeric substances, such as natural and/or synthetic rubber or the like, being applied to the top and/or bottom of this loose or precompacted mixture prior to hot-pressing and the said mixture being vulcanized during the said hot-pressing in such a manner that the said panels or moulded elements may be produced quite simply as heating or cooling devices. This is achieved in that, for the purpose of producing integrated hollow conduits, trough-like depressions, lined with the said vulcanizable layer, are produced in the surface of the base-material before or during the hot-pressing, the said depressions being covered by an additional layer which bridges them over.
