Abstract
The invention relates to a glazed module comprising a metal framework and an insulating glazing comprising a water-tight barrier, said insulating glazing being cold-bent, the metal framework and the insulating glazing being rendered integral by a holding means which forces the insulating glazing to retain the bent shape conferred on it by the framework. The invention also relates to a process for the preparation of the glazed module comprising a metal framework and an insulating glazing, the insulating glazing being cold-bent, after it has been assembled with a water-tight barrier, by a force which causes it to take the shape of the metal framework and then held in this bent shape by a holding means.
Claims30
A process for preparing a glazed module comprising a metal framework and an insulating glazing, the process comprising:
- cold-bending the insulating glazing at less than 200° C. by a force which causes it to take a bent shape of the metal framework;
- and then,
- holding the insulating glazing in the bent shape with a holder such that the metal framework and the insulating glazing are rendered integral by the holder, which forces the insulating glazing to retain the bent shape conferred on it by the framework,
- wherein the insulating glazing comprises glass substrates which are separated by a gas-filled cavity;
- and
- a water-tight barrier is placed between the glass substrates and framing the glazing.

- and then,
- holding the insulating glazing in the bent shape with a holder such that the metal framework and the insulating glazing are rendered integral by the holder, which forces the insulating glazing to retain the bent shape conferred on it by the framework,
- wherein the insulating glazing comprises a first glazing comprising a first glass substrate and a second glazing comprising a second glass substrate which are separated by a gas-filled cavity;
- and
- a water-tight barrier is placed between the first glass substrate and a second glass substrate and framing the insulating glazing.

- and then,
- holding the insulating glazing in the bent shape with a holder such that the metal framework and the insulating glazing are rendered integral by the holder, which forces the insulating glazing to retain the bent shape conferred on it by the framework,
- wherein the insulating glazing comprises two laminated glazings separated by a gas-filled cavity, each laminated glazing comprising two glass sheets separated by an interlayer made of polymer material.
