Title
(EN) HEAT INSULATION GLASS
(FR) VERRE D'ISOLATION THERMIQUE
(JA) 断熱ガラス
Abstract
(EN) A heat insulation glass having a glass substrate, in which the glass substrate has a first surface and a second surface that face each other, a laminate film is provided on the first surface of the glass substrate, the laminate film has an infrared ray reflection layer and an overcoat layer when observed from the side closer to the glass substrate, the arithmetical mean roughness Ra of the overcoat layer side surface of the infrared ray reflection layer is 9 nm to 24 nm, the overcoat layer is composed of an insulating material and is arranged so as to fill in rough parts on the infrared ray reflection layer, the arithmetical mean roughness Ra of a surface of the overcoat layer which is opposed to the infrared ray reflection layer is less than 7 nm, and the overcoat layer has a refraction index ranging from 1.35 to 1.70 and a largest thickness ranging from 120 nm to 241 nm.
