• Triple insulating glazings typically contain three panes of glass or polymeric materials separated by two individual spacers. It is placed on a double glazing by means of an additional spacer another disc. When mounting such a triple glazing very low tolerance requirements apply because the two spacers must be mounted in exactly the same height. Thus, the installation of triple glazing compared to double glazing is much more complex because either additional system components for the installation of another disc must be provided or a time-consuming multiple pass of a classic system is necessary.
