Abstract (en)

[origin: WO2021018861A1] The invention relates to a material comprising a transparent substrate coated on one face with a stack of thin layers comprising, successively from said face, an alternation of four silver-based functional metal layers and five dielectric coatings, said material being characterised in that: - the physical thickness Ea1 of the first functional layer Ag1 is less than the physical thickness Ea2 of the second functional layer Ag2, with 0.60 < Ea1/Ea2 < 0.90; - the physical thickness Ea1 of the first functional layer Ag1 is such that 8.00 ≤ Ea1 ≤ 13.00 nm; - the physical thickness Ea1 of the first functional layer Ag1 is less than the physical thickness Ea3 of the third functional layer Ag3, with 0.60 < Ea1/Ea3 < 0.90; and - the physical thickness Ea1 of the first functional layer Ag1 is less than the physical thickness Ea4 of the fourth functional layer Ag4, with 0.60 < Ea1/Ea4 < 0.90.
