ADIABATIC THREE-LAYER DOUBLE-GLAZED GLASS FOR WINDOW GLASS
To obtain an adiabatic three-layer double-glazed glass in which flexure of a glass sheet is suppressed even under a use environment large in a temperature difference between indoor and outdoor.SOLUTION: Two low radiation films are arranged on a surface on a hollow layer side of a first glass sheet that is a glass sheet arranged on the outermost outdoor side, and on one surface of a second glass sheet that is a glass sheet arranged between the two hollow layers, respectively, the glass sheet has a thickness of 2 to 6.5 mm, the first glass sheet has the solar absorptivity of 15% or larger and less than 45%, the second glass sheet has the solar absorptivity of less than 10%, a first hollow layer that is a hollow layer arranged on the outermost outdoor side is a layer in which a gas having the thermal conductivity at 20°C of 1.736 times or larger of the thermal conductivity of a dry air is filled and that is a layer having a thickness of 10 mm or smaller, and a second hollow layer that is a hollow layer arranged on the innermost indoor side is a layer in which a gas having the thermal conductivity at 20°C equal to or lower than the dry air is filled and that is a layer having a thickness of 4 mm or larger, and the heat transmission coefficient is 2.5 W/mK or smaller.SELECTED DRAWING: Figure 1
【課題】屋内と屋外の温度差が大きい使用環境でもガラス板のたわみを抑制した断熱性三層複層ガラスを得ること。【解決手段】２つの低放射膜は、最も屋外側に配置されたガラス板である第１ガラス板の中空層側の面、及び該２つの中空層の間に配置されたガラス板である第２ガラス板の片面にそれぞれ配置されるものであり、該ガラス板は、厚みが２〜６．５ｍｍであり、第１ガラス板は、日射吸収率が１５％以上、４５％未満であり、第２ガラス板は、日射吸収率が１０％未満であり、最も屋外側に配置された中空層である第１中空層は、２０℃における熱伝導率が乾燥空気の熱伝導率の１．７３６倍以上である気体が充填された、厚み１０ｍｍ以下の層であり、最も屋内側に配置された中空層である第２中空層は、２０℃における熱伝導率が乾燥空気以下である気体が充填された、厚み４ｍｍ以上の層であり、熱貫流率が２．５Ｗ／ｍ２Ｋ以下である、断熱性三層複層ガラス。【選択図】図１
