Glazing comprising a layer of superior protection CarbonWave hydrogen

The invention relates to a material comprising a transparent substrate coated with a stack acting on the infrared radiation comprising: - at least one functional layer and - at least one upper protective layer deposited over at least a portion of the layer functional, characterized in that the upper protection layer is a hydrogenated carbon layer in which the carbon atoms form carbon-carbon bonds and carbon-hydrogen and are essentially in an sp2 hybridization state.
