摘要:
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.
