Abstract
A vacuum glazing includes a vacuum layer formed between a first glazing and a second glazing, a spacer provided in the vacuum layer, a frame provided at edge portions of the first and second glazings, and a sealant interposed between the frame and surfaces of the first and second glazings to perform sealing of the vacuum layer. The insulating performance of the vacuum glazing is improved.
Claims20
A vacuum glazing comprising:
- a first glazing that has a first inner surface and a first side surface, the first side surface extending to a different direction from the first inner surface;
- a second glazing that is spaced apart from the first glazing, the second glazing having a second inner surface and a second side surface, the second side surface extending to a different direction from the second inner surface;
- a vacuum layer defined between the first glazing and the second glazing;
- a spacer located in the vacuum layer and configured to support the first glazing and the second glazing;
- a frame that is located at edge portions of the first glazing and the second glazing;
- and
- a sealant that is provided between the frame and at least one surface of the first glazing and between the frame and at least one surface of the second glazing, the sealant being configured to provide a sealing to the vacuum layer,
- wherein the sealant comprises:
- a first inner sealant part located on the first inner surface of the first glazing,
- a first side sealant part that is located on the first side surface of the first glazing and that connects to the first inner sealant part,
- a second inner sealant part located on the second inner surface of the second glazing, and
- a second side sealant part located on the second side surface of the second glazing.

A vacuum glazing comprising:
- a first glazing;
- a second glazing that faces the first glazing and that is spaced apart from the first glazing;
- a vacuum layer defined between the first glazing and the second glazing;
- a spacer located in the vacuum layer and configured to support the first glazing and the second glazing;
- a frame that is located at edge portions of the first glazing and the second glazing and that contacts each of the first glazing and the second glazing;
- a sealant that is provided between the frame and at least one surface of the first glazing and between the frame and at least one surface of the second glazing, the sealant being configured to provide a sealing to the vacuum layer;
- and
