Abstract
The invention relates to a multi-layered windowpane including a first transparent outer layer, a second transparent outer layer, and a third, smaller, transparent inner layer that is located in between the outer layers, an adhesive transparent foil layer located between the first outer layer and the third inner layer and a sealing surrounding the third inner layer. The invention also provides a thin layered windowpane core to be incorporated in such a multi-layered windowpane as well as a method for producing such a multi-layered windowpane.
Claims14
A multi-layered windowpane comprising:
- a first transparent outer layer,
- a second transparent outer layer, and
- a third, smaller, transparent inner layer that is located in between the outer layers such that the outer layers have respective peripheries that are greater than and extend beyond a periphery of the third transparent inner layer,
- a first adhesive transparent foil layer located between the first outer layer and the third inner layer and over an entire surface of the third inner layer such that the first adhesive transparent foil layer connects the third inner layer with the first outer layer;
- a fourth, thinner and smaller, transparent inner layer located in between the third inner layer and the second outer layer, such that the outer layers have respective peripheries that are greater than and extend beyond a periphery of the fourth transparent inner layer and;
- a second adhesive transparent foil layer located between the fourth inner layer and the second outer layer and over the entire surface of the fourth inner layer such that the second adhesive transparent foil layer connects the fourth inner layer with the second outer layer;
- a sealing surrounding both of the inner layers and gastight connecting outline borders of the outer layers;
- wherein a thickness of each of the outer layers is at least two times a thickness of each of the inner layers,
- wherein the multi-layered windowpane further comprises spacers distributed over a surface of the third inner layer facing towards the second outer layer, wherein the spacers are located in a free space adjacent the third inner layer, and wherein the free space is gastight separated from an outside air external to the multi-layered windowpane,
- wherein the first adhesive transparent foil layer covers an outside surface of the third inner layer,
- wherein the second adhesive transparent foil layer covers an outside surface of the fourth inner layer, and
- wherein the transparent adhesive foil layers both cover at least part of the sealing at a side of the sealing facing towards the respective outer layer.
