Abstract
A process for increasing resistance to penetration of glass in a glazed opening, including removing the glass from the glazed opening; and replacing the glass by laminated glazing consisting of the glass removed to which is fastened, by cementing with the aid of at least one intermediate layer of thermoplastic material, a sheet of thinner glass which has dimensions substantially equal to those of the glass removed except for having a thickness which is less than that of the glass removed, and which has been subjected to a chemical tempering treatment.
Claims8
A process for increasing resistance to penetration of glass in a glazed opening, the process comprising:
- removing the glass from the glazed opening;
- and
- replacing the glass by laminated glazing consisting of the glass removed to which is fastened, by cementing with the aid of at least one intermediate layer of thermoplastic material, a sheet of thinner glass which has dimensions substantially equal to those of the glass removed except for having a thickness which is less than that of the glass removed, and which has been subjected to a chemical tempering treatment.
A process for increasing resistance to penetration of glass in a glazed opening, the process comprising:
- removing the glass from the glazed opening;
- and
- replacing the glass by laminated glazing consisting of the glass removed or a pane of substantially identical geometry (hereinafter referred to as the "original glass pane") to which is fastened, by cementing with the aid of at least one intermediate layer of thermoplastic material, a sheet of thinner glass which has dimensions substantially equal to those of the original glass pane except for having a thickness which is less than that of the original glass pane, and which has been subjected to a chemical tempering treatment,
- wherein said original glass pane is a curved pane to which a plane sheet of thinner glass is fastened, and said sheet of thinner glass is cold curved during cementing in order to match the shape of said original glass pane.
