Claims
- 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.
- 2. The heat-insulating multiple glazing according to claim 1, wherein said low-radiating film has a heat-through ratio not exceeding 1 kcal/m.sup.2 hr.degree. C.
- 3. The heat-insulating multiple glazing according to claim 1, wherein said gap within said first vacuum multiple glazing is depressurized to be 10.sup.-3 Torr or lower.
- 4. The heat-insulating multiple glazing according to claim 2, wherein said gap within said first vacuum multiple glazing is depressurized to be 10.sup.-3 Torr or lower.
- 5. The heat-insulating multiple glazing according to claim 1, wherein said gap between the first vacuum multiple glazing and the second vacuum multiple glazing or the ordinary sheet glass is from 6 to 20 mm.
- 6. The heat-insulating multiple glazing according to claim 2, wherein said gap between the first vacuum multiple glazing and the second vacuum multiple glazing or the ordinary sheet glass is from 6 to 20 mm.
- 7. The heat-insulating multiple glazing according to claim 3, wherein said gap between the first vacuum multiple glazing and the second vacuum multiple glazing or the ordinary sheet glass is from 6 to 20 mm.
- 8. The heat-insulating multiple glazing according to claim 4, wherein said gap between the first vacuum multiple glazing and the second vacuum multiple glazing or the ordinary sheet glass is from 6 to 20 mm.
- 9. The heat-insulating multiple glazing according to claim 1, wherein said sealing material includes a primary sealing material and a secondary sealing material, the primary sealing material being isobutylene-isoprene rubber, the secondary sealing material being sulphide sealant or silicone sealant.
- 10. The heat-insulating multiple glazing according to claim 2, wherein said sealing material includes a primary sealing material and a secondary sealing material, the primary sealing material being isobutylene-isoprene rubber, the secondary sealing material being sulphide sealant or silicone sealant.
- 11. The heat-insulating multiple glazing according to claim 3, wherein said sealing material includes a primary sealing material and a secondary sealing material, the primary sealing material being isobutylene-isoprene rubber, the secondary sealing material being sulphide sealant or silicone sealant.
- 12. The heat-insulating multiple glazing according to claim 5, wherein said sealing material includes a primary sealing material and a secondary scaling material, the primary sealing material being isobutylene-isoprene rubber, the secondary sealing material being sulphide sealant or silicone sealant.
- 13. The heat-insulating multiple glazing according to claim 1 wherein the first and second vacuum multiple glazings respectively have a thickness of about 6 mm.
- 14. The heat-insulating multiple glazing according to claim 2 wherein the first and second vacuum multiple glazings respectively have a thickness of about 6 mm.
- 15. The heat-insulating multiple glazing according to claim 3 wherein the first and second vacuum multiple glazings respectively have a thickness of about 6 mm.
- 16. The heat-insulating multiple glazing according to claim 5 wherein the first and second vacuum multiple glazings respectively have a thickness of about 6 mm.
- 17. The heat-insulating multiple glazing according to claim 9 wherein the first and second vacuum multiple glazings respectively have a thickness of about 6 mm.
- 18. The heat-insulating multiple glazing according to claim 10 wherein the first and second vacuum multiple glazings respectively have a thickness of about 6 mm.
- 19. The heat-insulating multiple glazing according to claim 1 wherein each said sheet glass has a thickness of less than or equal to 1.5 mm and the spacers are disposed with a pitch not greater than 15 mm.
- 20. The heat-insulating multiple glazing according to claim 2 wherein each said sheet glass has a thickness of less than or equal to 1.5 mm and the spacers are disposed with a pitch not greater than 15 mm.
