Abstract
The invention relates to a transparent substrate (1), more particularly of glass, surmounted by a metal nitride layer (3) for filtering solar radiation, characterized in that with a view to protecting said metal nitride layer particularly against high temperature oxidation, said layer (3) is surmounted by a pyrolyzed, metal oxide layer (4), whose metal has an oxide formation standard free enthalpy value .DELTA.G.degree. equal to or below .DELTA.G.degree. of the metal of the nitride layer (3) at a given temperature.
