Abstract

A transparent coated substrate with high reflectance, especially for use as in exterior glazing panels for buildings, is provided by a substrate carrying a coating stack comprising a pyrolytically-formed main layer containing oxides of tin and antimony, in which the main layer has a geometric thickness of at least 250 nm and the stack includes an outer reflective layer having a geometric thickness in the range 30 to 150 nm and a refractive index in the range 2.0 to 2.8, whereby the so-coated substrate has a reflectance (RL) of more than 10%.
