Glass with a thin film coating that reflects infrared rays. It is also called infrared reflective glass. Because it transmits visible light and efficiently reflects infrared rays, when used as a building material, it can reduce the cooling load indoors and is expected to have an energy saving effect. In addition, its mirror-like appearance gives a beautiful look to buildings. For the thin film, metals and nitrides with high electrical conductivity, and oxides with high refractive index are used to enhance reflection. Thin films of metals and oxides are formed on the glass surface using chemical plating or sputtering (a method of forming a thin film on a substrate by colliding accelerated ions with a target to release atoms or molecules), or are obtained by pressing them into the glass surface as metal ions. Heat reflective glass is used for windows in office buildings, commercial buildings, public facilities, cultural facilities, and other places where anti-glare properties are required.

ガラス表面に、赤外線を反射する薄膜がコーティングされたガラス。赤外線反射ガラスともよばれる。可視光を透過し赤外線を効率よく反射するため、建材用として用いた場合には、室内の冷房負荷を低減でき、省エネルギー効果が期待できる。また、鏡のような外観を有することから建築物に美観を与える。薄膜には、反射を高めるために、高い電気伝導性を有した金属や窒化物、また高い屈折率を有した酸化物が用いられる。金属や酸化物の薄膜は、化学めっき法やスパッタリング法(加速したイオンをターゲットに衝突させて原子や分子を放出させることにより、基板上へ薄い膜を形成する方法)などを用いてガラス表面に成膜されたり、金属イオンとしてガラス表面に押し込むことで得られる。熱線反射ガラスは、事務所ビル、商業ビル、公共施設、文化施設などの窓、防眩(ぼうげん)性が要求される場所に用いられる。 [伊藤節郎] 『作花済夫・伊藤節郎・幸塚広光・肥塚隆保・田部勢津久・平尾一之・由水常雄・和田正道編『ガラスの百科事典』(2007・朝倉書店)』 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
