Abstract
The invention relates to a spacer for an insulating glazing assembly. The spacer has two mutually parallel extending contact surfaces for the respective glass panes and an adhesion surface facing away from the interior space between the glass panes. The adhesion surface connects the two contact surfaces. The spacer includes a metal layer disposed on the adhesion surface. The metal layer is cemented to the adhesion surface, and the amount of short-fibred glass-fibers in the plastic is selected such that the coefficient of thermal expansion of the base body is adapted to the thermal expansion of the metal-layer.
Claims14
A spacer for an insulating glazing assembly which includes at least two mutually adjacent glass panes conjointly defining an interior space therebetween, the spacer being disposed between said glass panes and the spacer comprising:
- a base body made of plastic and having two mutually parallel contact surfaces on opposite sides thereof in contact engagement with corresponding ones of said glass panes;
- said base body being reinforced by glass fibers distributed in said plastic;
- said base body also defining an adhesion surface facing away from said interior space and extending between said two glass panes;
- a metal layer cemented to said adhesion surface;
- and
- said glass fibers being selected in amount such that the coefficient of thermal expansion of said base body corresponds substantially to the thermal expansion of said metal layer.
A spacer for an insulating glazing assembly which includes at least two mutually adjacent glass panes conjointly defining an interior space therebetween, the spacer being disposed between said glass panes and said spacer comprising:
- a base body made of plastic having two mutually parallel contact surfaces on opposite sides thereof in contact engagement with corresponding ones of said glass panes;
- said base body being reinforced by glass fibers distributed in said plastic;
- said base body defining an adhesion surface facing away from said interior space and extending between said two glass panes;
- a vapor-deposited metal layer disposed on said adhesion surface;
- and,
- said glass fibers being selected in amount such that the coefficient of thermal expansion of said base body corresponds substantially to the thermal expansion of said vapor-deposited metal layer.
