Acristalamiento transparente, dotado de un apilamiento de capas delgadas que actúan sobre la radiación solar, caracterizado porque presenta una transmisión luminosa TL de 5 a 55%, en particular de 8 a 45%, y un factor solar FS inferior a 50%, en particular cercano al valor de transmisión luminosa, y porque dicho apilamiento comprende al menos una capa funcional de carácter esencialmente metálico y que comprende mayoritariamente niobio, estando sobre dicha capa funcional al menos una sobrecapa a base de nitruro de aluminio, de oxinitruro de aluminio, de nitruro de silicio, o de oxinitruro de silicio, o de una mezcla de al menos dos de esos compuestos. A coated transparent substrate has a metallic or nitrided niobium, tantalum and/or zirconium functional layer and an aluminum and/or silicon nitride and/or oxynitride cover layer. A transparent substrate has a solar radiation active thin film stack comprising a functional layer based on metallic or partially or fully nitrided niobium, tantalum and/or zirconium covered by a layer based on aluminum nitride, aluminum oxynitride, silicon nitride and/or silicon oxynitride. Independent claims are also included for the following: (i) single or double glazing incorporating the above substrate; and (ii) a curtain wall-type facade face panel incorporating the above substrate with an opaque coating. Preferred Features: The substrate consists of clear or tinted glass or a flexible or rigid transparent polymer.
