  • Multi-glazed windows are colloquially called multi-pane insulating glass. This type of glazing is primarily used for thermal insulation, that is, the prevention of heat loss to a cold environment or the prevention of heating of the interior by a relatively warmer environment.
  • Multi-glazed windows usually consist of at least two glass panes arranged in parallel, which are spaced from a spacer. The result is between the glass panes, a space between the panes, which, filled with air or gas, represents an insulating layer.

  • spacers with a cavity which contains a desiccant for drying the trapped air in the space between the panes.
  • Spacers are usually designed so that they prevent the Dif ⁇ fusion of water vapor from outside the space between the panes in the space between the panes and at the same time the Ensure gas and water vapor exchange between the atmosphere of the space between the panes and the desiccant.
  • plastic spacers are manufactured in one piece by profile extrusion. The cavity is then subsequently filled with a desiccant.
