Zusammenfassung: | A material comprising a transparent substrate deposited with a stack of thin layers on at least one of its surface for thermal insulation and aesthetic properties is disclosed. The stack of thin layers successively comprises, starting from the substrate not more than two metallic functional layers based on silver F1, F2 and three dielectric coatings M1, M2, M3 comprising at least one dielectric layer such that each of the metallic functional layer is sandwiched between two dielectric coatings. The material comprising said stack of thin layers exhibits blue color in external reflection (Rext); preferably neutral color in internal reflection (Rint) and has less than 20% reflection internally and externally. Additionally, the material has a high selectivity while retaining a light transmission in the visible spectrum as high as 70%.
Se divulga un material que comprende un sustrato transparente depositado con una pila de capas delgadas en al menos una de sus superficies para el aislamiento térmico y propiedades estéticas. La pila de capas delgadas comprende sucesivamente, a partir del sustrato, no más de dos capas funcionales metálicas basadas en plata F1, F2 y tres recubrimientos dieléctricos M1, M2, M3 que comprenden al menos una capa dieléctrica de manera que cada una de las capas funcionales metálicas está intercalada entre dos recubrimientos dieléctricos. El material que comprende dicha pilas de capas delgadas exhibe color azul en reflexión externa (Rext); preferiblemente neutro en reflexión interna (Rint) y tiene menos de 20% de reflexión interna y externamente. Adicionalmente, el material tiene una alta selectividad mientras que mantiene una transmisión de luz en el espectro visible tan alta como 70%. |
