Zusammenfassung: | A window spacer may include a spacer substrate having two pane contact surfaces, an adhesive surface, and a glazing interior surface. A multilayer barrier film is in contact with the adhesive surface of the spacer substrate. The multilayer barrier film includes at least two first polymeric layers and at least two inorganic layers. The inorganic layers are separated by a second polymeric layer. The second polymeric layer has a thickness lower than 5 μm, preferably lower than 4 μm, more preferably having a thickness between 1 μm and 4 μm. |
