Solar control glazing
First Claim
1. A solar control panel comprising a glazing substrate and a solar control coating in which the solar control panel exhibits a luminous transmittance of less than 70%, a direct energy transmittance of less than 40% and a dominant wavelength in reflection of less than 510 nm and in which the solar control coating comprises in sequence from the glazing panel at least:
- a first antireflective layer adjacent;
a first infra-red reflecting layer;
a first barrier layer;
a second antireflective layer;
a second infra-red reflecting laser;
a second barrier layer; and
a third antireflective layer;
characterised in that the solar control coating comprises at least one additional light absorbing layer spaced from each of the barrier layers.
