Abstract
A solar control transparent glass sheet is provided by a soda-lime glass sheet carrying a coating of at least two pyrolytically-formed layers, characterised by the presence in the coating of a conductive or semi-conductive layer having a thickness in the range 15 to 500 nm and formed of a material comprising a metal oxide containing a dopant in an amount of from 1 to 100 moles per 100 moles of the metal oxide, the said metal oxide being selected from one or more of tungsten trioxide (W03), molybdenum trioxide (MoO3), niobium pentoxide (Nb2O5), tantalum pentoxide (Ta2O5), vanadium pentoxide (V2O5) and vanadium dioxide (VO2), whereby the so-coated sheet has a neutral or blue tint in transmission and in reflection, a luminous transmittance (TL) which is in the range 30 to 85% and a selectivity of greater than 1, preferably greater than 1.2.
