Abstract

A glazed unit of curved form includes a first glass sheet with a thickness of less than 1.6 mm, a second glass sheet having a thickness of less than 1.6 mm, an intermediate film with a thickness of less than the thickness of the thinnest glass sheet of the glazed unit and arranged between the first glass sheet and the second glass sheet, the glazed unit further including a seal encapsulating all the sides of the glazed unit.

Claims (11)

4 . The glazed unit according to claim 1 , wherein the seal is reinforced by a reinforcing member. cm 5 . The glazed unit according to claim 4 , wherein the reinforcing member comprises at least one metal wire embedded in the seal. cm 6 . The glazed unit according to claim 1 , wherein the interlayer film is a sheet made of a PVB or PET type material. cm 7 . The glazed unit according to claim 1 , wherein the interlayer film is a layer deposited on one of the two glass sheets of said glazed unit. cm 8 . The glazed unit according to claim 7 , wherein the layer forming the interlayer film is an optical clear adhesive (OCA) resin or a natural rosin. cm 9 . The glazed unit according to claim 1 , one of the preceding claims, wherein the glazed unit has a maximum deflection of 70 mm. cm 10 . The glazed unit according to claim 1 , wherein the glazed unit has a thickness not exceeding 4 mm. cm 11 . The glazed unit according to claim 1 , wherein the glazed unit has a maximum surface area of 0.8 m 2 . cm 12 . A method for manufacturing a glazed unit of curved shape comprising a first glass sheet with a thickness of less than 1 . 6 mm, a thermoplastic interlayer sheet and a second glass sheet having a thickness of less than 1 . 6 mm, said method comprising:

obtaining the first glass sheet in flat form, the second glass sheet in flat form and the interlayer film;

assembling the first glass sheet in flat form, the second glass sheet in flat form and the interlayer film with the interlayer film between the two glass sheets to form an assembly;

placing the assembly in an encapsulation device capable of surrounding the sides of the assembly with a seal;

putting the seal in place;

wherein said encapsulation device is capable of deforming the glazed unit during the placement of the seal. cm 13 . The method of the claim 12 , wherein it further comprising, before the assembly step, a step of chemically or thermally strengthening the first glass sheet and/or the second glass sheet.

14 . The glazed unit according to claim 1 , wherein the first glass sheet has a thickness of less than 1.2 mm and the second glass sheet has a thickness of less than 1.2 mm.

15 . The laminated glazed unit according to claim 2 , wherein the first glass sheet has a thickness of less than 1.2 mm and the second glass sheet has a thickness of less than 1.2 mm.

16 . The glazed unit according to claim 10 , wherein the glazed unit has a thickness not exceeding 3 mm.

17 . The glazed unit according to claim 16 , wherein the glazed unit has a thickness not exceeding 2 mm.

18 . The method according to claim 12 , wherein the first glass sheet has a thickness of less than 1.2 mm and the second glass sheet has a thickness of less than 1.2 mm.
