A Plastic Spacer Comprising a Layer with Overlapping Segments of a Substantially Gas-Impermeable Material
The present invention relates to a spacer for creating a spacing between glass panes, wherein said spacer is made of a plastic material. The spacer is elongated and comprises two side surfaces as well as a top surface and a bottom surface with a layer having gas-impermeable characteristics, wherein this layer comprises multiple overlapping segments of a substantially gas-impermeable material. Further, the present invention relates to a method of manufacturing such a spacer and a window comprising glass panes being mutually spaced by such a spacer. By letting the segments overlap, it is ensured that gas-impermeability of the spacer is significantly increased. Further, the overlapping of segments results in that a spacer with such a layer can be bent without compromising the gas-impermeability. When bending a spacer in corners to correspond to the shape of a glass pane, then the segments in the layer will still overlap, whereby gas-impermeability is maintained in the corners. Further, the overlapping ensures that a foil with such overlapping segments can be mounted across corners without comprising gas impermeability.
