Insulating double-glazing unit and vacuum double-glazing unit
First Claim
1. A heat-insulating multiple glazing comprising:
- a first vacuum multiple glazing including two sheets of glass having peripheries thereof sealed and a plurality of spacers disposed within a gap therebetween, the gap being depressurized;
a second vacuum multiple glazing or an ordinary sheet glass, said second vacuum multiple glazing or ordinary sheet glass being overlapped with the first multiple glazing with a gap relative thereto and having the periphery thereof sealed with a sealing material, said gap being charged with dry air or rare gas;
a low-radiating film formed on either one or both of an opposing inner face of the second vacuum multiple glazing or the ordinary sheet glass opposing the first vacuum multiple glazing and an opposing inner face of the first vacuum multiple glazing opposing the second vacuum multiple glazing or the ordinary sheet glass.

Abstract
The present invention relates to a heat-insulating multiple glazing and a vacuum multiple glazing. Conventionally, this type of glass does not provide sufficient heat-insulating performance. And, it has been necessary to form the heat-insulating multiple glazing thick, in order to enhance the heat-insulating performance. The present invention comprises a first vacuum multiple glazing (2) including two sheet glasses (3), (4) having peripheries thereof sealed and a plurality of layers of spacer (5) disposed within a gap therebetween, with the gap being depressurized; and a second vacuum multiple glazing (2) or an ordinary sheet glass (10) overlapped with the first multiple glazing (2) with a gap relative thereto and having the periphery thereof sealed with a sealing material (12), with the gap being charged with dry air or rare gas. Thus, it is possible to enhance the heat-insulating performance, without increasing the thickness of the entire heat-insulating multiple glazing.
