Abstract
The present invention relates to a method for manufacturing vacuum insulating glass, the method involving applying a vacuum sealant to a first surface of a first glass sheet, the vacuum sealant including a plastic film having a preferably rough surface, placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant, applying a vacuum to an outer surface of the vacuum sealant until a vacuum is formed in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum, and heating the vacuum sealant while the first and second glass sheets are in the vacuum bag.
Claims14
A method of manufacturing vacuum insulated glass, the method comprising:
- applying a vacuum sealant to a first surface of a first glass sheet, wherein the vacuum sealant comprises a plastic film;
- placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant;
- applying a vacuum to an outer surface of the vacuum sealant until a vacuum is established in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum;
- heating the vacuum sealant while the first and second glass sheets are in the vacuum bag;
- applying a barrier prior to placing the second glass sheet, the barrier being disposed between the cavity and the vacuum sealant;
- and
- wherein the barrier comprises at least two mitered portions that are juxtaposed on the first surface of the first glass sheet such that a miter joint is formed.
A method of manufacturing vacuum insulated glass, the method comprising:
- applying a vacuum sealant to a first surface of a first glass sheet, wherein the vacuum sealant comprises a plastic film;
- placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant;
- applying a vacuum to an outer surface of the vacuum sealant until a vacuum is established in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum;
- heating the vacuum sealant while the first and second glass sheets are in the vacuum bag;
- applying a barrier prior to placing the second glass sheet, the barrier being disposed between the cavity and the vacuum sealant;
- and
- wherein the barrier comprises at least two strips which are spaced apart from each other at their abutting edges by 0.5 mm to 2 mm.
