Edge union for insulating glazing - involves three or more panes of glass with two transparent outer substrates and at least one transparent intermediate inner substrate

摘要

Between adjacent substrates (1-3) are edge-side distance holders (6-9), which hold the substrates at a predetermined distance. A sealing medium (20,21) seals a gas in a moisture-tight manner in the intermediate spaces (10,11) between the substrates inside the distance holders. The outer substrates (1,2) extend over the inner substrate (3) in its edge area (4,5) and the sealing medium (20,21) extends into the area extended over by the outer substrates, covering both the distance holders and the inner substrate. The transparent substrates are glass panes, partic. float glass panes, and the sealing medium is formed by polysulphide or polyurethane or silicon. USE/ADVANTAGe - As a three-pane insulation glazing. The inner pane is subjected to a low thermic tension and the sealing mass is applicable in the edge area simply, preventing the formation of free spaces.
