Multiple glazing unit incorporating at least one antireflective coating and use of the antireflective coating in multiple glazing units

摘要

A multiple glazing unit with at least three substrates which are held together by a frame structure, in which at least two intermediate gas-filled cavities lie each between two substrates, at least one substrate has, on at least one face in contact with an intermediate gas-filled cavity, an antireflection film which is in a face-to-face relationship relative to said intermediate gas-filled cavity, with an insulating film having reflection properties for infrared and/or in solar radiation.
