Title (EN) WINDOW GLASS AND TRANSPARENT SUBSTRATE PROVIDED WITH LAYERED FILM
(FR) VERRE À VITRE ET SUBSTRAT TRANSPARENT MUNI DE FILM STRATIFIÉ
(JA) 窓ガラスおよび積層膜付き透明基板
Abstract:
(EN) Provided are a window glass having high heat-insulation properties which is suitable for use in hot regions from low latitudes to middle latitudes, and a transparent substrate provided with a layered film and having high heat-insulation properties. A window glass comprising a transparent substrate provided with a layered film, having a transparent substrate and a layered film formed on the transparent substrate, the window glass being used in a state in which the layered film is exposed to the atmosphere on an indoor side, the heat transmission coefficient (U value) being 3.4-4.7 W/m2∙K, the solar heat gain coefficient (η value) being 0.17-0.44, and the visible light transmittance (Tv) being 35% or greater as measured in accordance with JIS R3106/3107 (1998), the color rendering properties of transmitted light evaluated by general color rendering index (Ra) using a D65 light source in accordance with JIS Z8726 (1990) being 90% or greater, and the number of defects in a 1 mm × 1 mm range being 50 or less as measured by observing the surface of the layered film using a microscope (at 50x magnification) after a three-day sweat resistance test in accordance with ISO 12870.
(FR) L'invention concerne un verre à vitre présentant des propriétés d'isolation thermique élevées, qui convient à une utilisation dans des régions chaudes de basses latitudes à des latitudes médianes, et un substrat transparent muni d'un film stratifié et présentant des propriétés d'isolation thermique élevées. Le verre à vitre comprend un substrat transparent muni d'un film stratifié, ayant un substrat transparent et un film stratifié formé sur le substrat transparent, le verre à vitre étant utilisé dans un état dans lequel le film stratifié est exposé à l'atmosphère sur un côté intérieur, le coefficient de transmission thermique (valeur U) étant de 3,4 à 4,7 W/m2∙K, le coefficient de gain de chaleur solaire (valeur η) étant de 0,17 à 0,44, et la transmittance dans la lumière visible (Tv) étant de 35 % ou plus, telle que mesurée selon la norme JIS R3106/3107 (1998), les propriétés de rendu des couleurs de la lumière transmise évaluées par l'indice de rendu des couleur général (Ra) au moyen d'une source de lumière D65 selon la norme JIS Z8726 (1990) étant de 90 % ou plus, et le nombre de défauts dans une plage 1 mm x 1 mm étant de 50 ou moins tel que mesuré par observation de la surface du film stratifié à l'aide d'un microscope (au grossissement 50x) après un test de résistance à la transpiration de trois jours selon la norme ISO 12870.
(JA) 低緯度から中緯度の暑熱地域での使用に適した高遮熱性の窓ガラスおよび高遮熱性の積層膜付き透明基板を提供する。透明基板と前記透明基板上に成膜された積層膜を有する積層膜付き透明基板からなり、前記積層膜が室内側の大気に露出した状態で使用され、JIS R3106/3107(1998)に準拠して測定される熱貫流率(U値)が3.4~4.7W/m・K、日射熱取得率(η値)が0.17~0.44、および可視光透過率(Tv)が35%以上であり、 JIS Z8726(1990)に準拠してD65光源を使用し平均演色性評価数(Ra)により評価される透過光の演色性が90%以上であり、ISO12870に準拠した3日間の耐汗試験後に前記積層膜表面を顕微鏡(50倍)で観察して計測される、1mm×1mmの範囲における欠点数が50以下である窓ガラス。
