Abstract: A corner connector for connecting two hollow-profile strips of an insulating glazing unit is presented. The corner connector includes a first plug-in leg, a second plug-in leg, a corner region, and a capillary tube with a first opening and a second opening. According to one aspect, the corner region connects the second plug-in leg to the first plug-in leg so to form angle between 45° and 180° between the two plug-in legs. According to another aspect, the first plug-in leg, the second plug-in leg, and the corner region are injection molded, and the capillary tube is integrally molded into the corner region. When installed, the capillary tube establishes a connection between the inner interpane space and corresponding surroundings of the insulating glazing unit.

Abstract: A connector for connecting two hollow-profile strips of an insulating glazing unit is presented. The connector includes two plug-in legs suitable for insertion into the hollow-profile strips, and a connection region where the two plug-in legs are connected. The connection region includes an outer surface, two pane contact surfaces, and an inner surface. According to one aspect, the connector includes a cavity to establish a passage from the inner interpane space to corresponding surroundings of the insulating glazing unit. According to another aspect, the cavity has a first opening in the outer surface of the connection region that is sealed with a gas-permeable and water-vapor-tight membrane.

Abstract: A spacer for insulating glazing units is presented. The spacer has a polymeric main body with features that include a first pane contact surface, a second pane contact surface, a first glazing interior surface, a second glazing interior surface, an outer surface, a first hollow chamber, and a second hollow chamber. A groove to accommodate a pane is formed between the first glazing interior surface and the second glazing interior surface, with the first hollow chamber being adjacent the first glazing interior surface and the second hollow chamber being adjacent the second glazing interior surface. Lateral flanks of the groove are formed by walls of the first and second hollow chambers.
