ADIABATIC THREE-LAYER MULTIPLE GLASS FOR WINDOW GLASS
To provide an adiabatic three-layer multiple glass using a low radiation film used as a window glass, in which deflection of a glass sheet is suppressed even under use environment large in temperature difference between indoor and outdoor.SOLUTION: There is provided an adiabatic three-layer multiple glass for window glass having 3 glass sheets, 2 hollow layers which are single closed spaces arranged between the glass sheets, and a low radiation film, in which the glass sheet has thickness of 2 to 6.5 mm, and 3 of them have same thickness, the low radiation film is arranged only on a surface in a hollow layer side of a first glass sheet which is the glass sheet arranged at most outdoor side, solar absorptivity of the first glass sheet is 15% or more and less than 63%, and heat transmission coefficient is 2.5 W/mK or less.SELECTED DRAWING: Figure 1
【課題】本発明は、窓ガラスとして用いられる低放射膜を用いた断熱性三層複層ガラスにおいて、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を目的とした。【解決手段】３枚のガラス板と、該ガラス板の間に設けられた単一の密閉空間である中空層を２つと、低放射膜と、を有する窓ガラス用断熱性三層複層ガラスにおいて、該ガラス板は、厚みが２〜６．５ｍｍ、かつ３枚が同厚であり、該低放射膜は、最も屋外側に配置されるガラス板である第１ガラス板の、中空層側の面にのみ配置されるものであり、該第１ガラス板の日射吸収率が１５％以上、６３％未満であり、熱貫流率が２．５Ｗ／ｍ２Ｋ以下である、窓ガラス用断熱性三層複層ガラス。【選択図】図１
