REDUCED PRESSURE DOUBLE GLAZED GLASS PANEL
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.
