Abstract

A process for manufacturing a laminated glass window equipped with sealing at one or more edges, wherein the laminated glass window contains at least two glass sheets and laminated plastic placed between the two glass sheets, wherein the laminated plastic is made of at least one principal carrier sheet, having on at least one side at least one layer that reflects infrared radiation and outer layers made of one or more thermoplastic polymers; the process involving: PA1 a) forming a plate from the laminated plastic, the plate having a geometrical shape substantially the same as the glass sheets, but wherein the plate is shorter, by an offset distance, on each of one or more edges to be sealed; PA1 b) preparing a preliminary laminated sheet by positioning the plate in relation to the glass sheets while respecting the offset distance on each of the one or more edges to be sealed and removing air from between the layers formed by the glass sheets and the plate; PA1 c) filling the interstice of the one or more edges to be sealed by injecting a melted material containing one or more polymers compatible with the one or more thermoplastic polymers of the outer layers of the laminated plasti…
