Abstract
The invention relates to a vacuum insulated glass, which comprises two or more glass plates, which can be evacuated, which are oriented in parallel and which are sealed air-tight at the outer edge, with respect to the interior formed by means of spacers, by means of strip-shaped connecting elements attached to the entire perimeter, in particular metal strips connected to each other in a vacuum-tight manner, having the following features: a) the spacers each comprise at least two segments (7, 9) associated with each other, b) the spacers are arranged on closed distribution lines, which are arranged at a distance from each other and extend substantially parallel to the perimeter of the glass plate in question and run out in a defined manner in a curve in the corner regions of the glass plate, c) the segments (7, 9) are made of different materials, and d) the segments (7, 9) have a coating and/or structuring on the surfaces that do not come in contact with the glass plates (5, 6). The invention further relates to a method for producing the vacuum insulated glass.
