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.

摘要:
The present invention provides a glass member including a photocatalyst layer and a heat reflecting layer, the glass member having high photocatalytic activity and exhibiting a low reflectance and a colorless or pale blue reflection color tone or a bluish green or green reflection color tone. The glass member is produced by laminating an antistripping layer made of silicon oxide or the like, a crystalline undercoat layer made of zirconium oxide or the like and a photocatalyst layer made of titanium oxide or the like on the other surface of a glass substrate having a heat reflecting layer formed on one surface thereof. The heat reflecting layer is formed such that the other surface of the glass substrate has a reflection chromaticity (a*, b*) satisfying -4≤a*≤2 and -5≤b*≤0 and a visible light reflectance of 10% or less, the crystalline undercoat layer is allowed to have a thickness ranging from 2 to 28 nm, and the photocatalyst layer is allowed to have a thickness ranging from 2 to 20 nm, whereby the glass member having a colorless or pale blue reflection color tone can be produced. Likewise, the heat reflecting layer is formed such that the reflection chromaticity (a*, b*) satisfies -15≤a*≤-2 and -10≤b*≤10 and the visible light reflectance is 13% or less, the crystalline undercoat layer is allowed to have a thickness ranging from 2 to 28 nm, and the photocatalyst layer is allowed to have a thickness ranging from 2 to 14 nm, whereby the glass member having a bluish green or green reflection color tone can be produced.
