| abstract |
The invention relates to a laminated fire-resistant glass unit having at least two transparent carrier elements, in particular glass panes, and an intermediate layer between the carrier elements, this layer expanding for example in the event of a fire, or a gas-releasing intermediate layer, which builds up a pressure between the carrier elements. The invention is distinguished substantially in that at least one glass pane (2) of the laminated fire-resistant glass unit, preferably the two outermost glass panes, or even all the glass panes adjacent to an intermediate layer, are provided with specific local weakening as a defined breaking point. A predetermined breaking point may be, for example, a groove or milled recess, in particular a notch (25). |
