<p>Heat-insulating glass pane consisting of three single glass sheets (1,2,3), of which the middle sheet (2) and a further sheet (3) have a coating (12,13) on a surface facing the sheets intermediate space, is novel in that the glass sheets (1,2,3) have a low content of irradiation-absorbing ions such that, at a sheet thickness of about 4 mm, their integrated transmission in the spectral region between 300 and 2500 nm in the uncoated state is at least 86%, and that the coating (12,13) has an emissivity epsilon of < 0.1.</p> |
