Abstract: A multiple-glazed glass unit of the present invention is adapted to separate an indoor space and an outdoor space and includes a pair of glass panes opposed across a gap layer to be spaced at a predetermined distance from each other. Low-emissivity (Low-E) films are formed on both principal surfaces of one of the pair of glass panes that is located closer to the indoor space. The low-emissivity film formed on one of the two principal surfaces that faces the indoor space has an arithmetic average surface roughness Ra of 14 nm or less. This multiple-glazed glass unit is configurable to have a higher SHGC value ever than before as well as keeping a low U-value.

Abstract: A heat insulating and shielding glass panel that is capable of maintaining heat shielding performance even if heat treatment is carried out during manufacture. The heat insulating and shielding glass panel 1 is comprised of a pair of glass plates 11 and 12 that are hermetically joined together at their outer peripheral edges via a sealing frame 13 that fluidizes at low temperature, such that respective one surfaces of the glass plates 11, 12 face each other and a hollow layer 14 is formed between the glass plates; and pillars 15 that are substantially cylindrical spacers that are inserted into the hollow layer 14 as atmospheric pressure supporting members and determine the gap between the glass plates 11 and 12. A low-emission transparent multilayer 17 having an emittance of not more than 0.1 is coated by sputtering on each of surfaces 11a and 12a of the respective glass plates 11 and 12 facing the hollow layer 14 so as to realize high heat insulation performance.
