グレー色調低放射ガラス
Document Type and Number:
Japanese Patent JP6767661
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gray color tone low radiation glass of which appearance by visual inspection exhibits a gray color tone and which can suppress a color tone of a reflection color.SOLUTION: There is provided a gray color tone low radiation glass in which a low radiation film having one Ag layer is formed on a glass sheet surface and of which a penetrated color exhibits a gray color tone, the low radiation film is manufactured by laminating a first dielectric layer, the Ag layer, a second dielectric layer, a light absorption layer and a third dielectric layer from a glass sheet surface in this order, an optical film thickness of the first dielectric layer is 45 to 80 nm, physical film thickness of the Ag layer is 7 to 10 nm, total optical film thickness of the second dielectric layer and the third dielectric layer is 75 to 110 nm, and film thickness of the second dielectric layer based on total value of film thickness of the second dielectric layer and the third dielectric layer is 18 to 55%.SELECTED DRAWING: Figure 1
