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 µ) ¤ 0.067; 31% ¤ (Solar reflectance on First glass surface R G(solar) ) ¤ 40%; (48 - R G(solar) )% ¤ (Solar absorptance on First glass surface A G(solar) ) ¤ 17%; (A G(solar) ) ¤ {18.3 - (0.07 × R G(solar) ) + (20 × µ)}%; (Solar heat gain coefficient SHGC) ¤ 0.50; and (Thermal transmittance U value) ¤ 1.2 W/m 2 ¢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.
