1. A coated glass sheet comprising:
a glass substrate; and
a UV reflecting coating on at least one major surface of the glass substrate,
wherein the UV reflecting coating consists of first, second, and third layers in this order moving away from the glass substrate,
wherein the first and third layers comprise a dielectric material selected from the group consisting of a mixed oxide of titanium and zirconium, and a mixed nitride of zirconium and silicon,
the second layer comprises silicon oxide SiOx,
wherein the first layer and the third layer are identically patterned so that the first layer and the third layer are not provided continuously across the entire coated glass sheet, and
wherein the second layer is provided over the entire coated glass sheet.
