The invention provides coated glass and vehicle window glass. The coated glass comprises a substrate and a low-permeability heat insulation layer arranged on at least one surface of the substrate, the low-permeability heat insulation layer comprises at least two dielectric layers and at least two absorption function layers which are arranged in a stacked mode, and each absorption function layer is located between the two adjacent dielectric layers; the visible light transmittance of the coated glass is less than or equal to 15%. By arranging the low-transmittance heat insulation layer, the coated glass has lower visible light transmittance TL and lower radiance e, and can replace a dark PVB (Polyvinyl Butyral) membrane in related technologies, so that the coated glass has the effects of low cost, simplicity in manufacturing and production and privacy protection. Moreover, the coated glass can be independently used as the vehicle window glass and can also be made into the vehicle window glass, heat can be blocked, a sunshade curtain in a vehicle is omitted, and therefore a larger height space in the vehicle is obtained, and the use experience of a user is improved.
本申请提供了镀膜玻璃及车窗玻璃。镀膜玻璃包括基板和设置于基板的至少一个表面上的低透隔热层,低透隔热层包括层叠设置的至少两个介质层和至少两个吸收功能层,每个吸收功能层位于相邻的两个介质层之间;镀膜玻璃的可见光透过率小于或等于15%。本申请通过设置低透隔热层,使镀膜玻璃具有较低的可见光透过率TL与较低的辐射率e,可替代相关技术中深色PVB膜片,从而使镀膜玻璃具有成本低、制造生产简单、保护隐私的效果。并且,镀膜玻璃可以单独使用作为车窗玻璃,也可以制作成车窗玻璃作为车窗玻璃,能够阻隔热量,省略车辆内遮阳帘的设置,从而获得更大的车辆内部高度空间,提高了用户的使用体验。
