Abstract

See full text

The reduced pressure double glazed glass panel of the present invention includes an outside glass sheet, an inside glass sheet, and a gap portion that are joined together, with the gap portion being formed between the glass sheets and sealed under reduced pressure. Here, the outside glass sheet has a first glass surface disposed to face the outdoor space and a second glass surface disposed to face the gap portion. A Low-E film is formed on the second glass surface. The following relations hold: (Emissivity of Low-E film ∈)≦0.067; 31%≦(Solar reflectance on First glass surface RG(solar))≦40%; (48−RG(solar))%≦(Solar absorptance on First glass surface AG(solar))≦17%; (AG(solar))≦{18.3−(0.07×RG(solar))+(20×∈)}%; (Solar heat gain coefficient SHGC)≦0.50; and (Thermal transmittance U value)≦1.2 W/m2·K or less. According to the present invention, it is possible to provide a reduced pressure double glazed glass panel having sufficient heat insulating and heat shielding properties and being less susceptible to bending when exposed to solar radiation.
