The present invention relates to coated fiber cement products as well as to methods for manufacturing such products. In particular, the present invention provides processes for manufacturing coated fiber cement products, these processes comprising the IN steps of: (i) providing a cured fiber cement product having at least one surface; (ii) applying a primer to the at least one surface of the cured fiber cement product; (iii) providing at least one layer of a radiation curable composition to the at least one surface, which radiation curable composition comprises at least one pigment; and (iv) curing the layer of radiation curable composition by radiation. Finally, the present invention provides coated fiber cement products obtainable by such processes and uses of these fiber cement products as building materials. In particular embodiments, the coated fiber cement products produced by the processes of the present invention can be used to provide an outer surface to walls, both internal as well as external, a building or construction, e.g. as fa?ade plate, siding, roofing element, etc. such as for instance a slate.

A part includes a substrate made of ceramic matrix composite material, the substrate being coated with a multilayer stack including at least, and in this order, starting from the substrate a tie layer including silicon; an insulation layer including a rare earth disilicate or silica; a barrier layer including a rare earth disilicate; the part further including at least one thermocouple inserted between the insulation layer and the barrier layer.
