Abstract
A light transmitting glazing pane includes a first coating on an exposed face of a glass sheet which reduces the emissivity of that face in respect of infra-red radiation having wavelengths in excess of 3 .mu.m, and on the or another face of the pane a solar radiation screening coating which is adapted to screen short wavelength infra-red radiation, the thickness of each coating being selected so that the pane has a visible light transmissivity of at least 70% and a total solar radiant energy transmissivity of at most 75%. Such panes are useful for limiting solar energy gain while allowing good through visibility, and they may therefore be used to form vehicle windows.
