Abstract
A heat insulating/heat shielding glass panel is produced by forming a functional film on a sheet of plate glass, which film is high in solar radiation reflectance, small in solar radiation absorptivity, and has emissivity of 0.20 or less, superposing another sheet of plate glass on the side of the functional film, and adhesively sealing the two sheets of plate glass, under the condition that a gap layer is provided between the two sheets of plate glass. Accordingly, there is obtained a glass panel which has a sufficient heat insulating performance and a sufficient heat shielding performance, and in which no warping is generated even when suffering the solar radiation.
