Abstract

A spacer for a multiple-pane insulating glazing unit, at least having a composite composed of a glass-fiber-reinforced, polymeric main body having two pane contact surfaces, which extend parallel to one another, an adhesive surface, a glazing interior surface, and an insulation film on the adhesive surface or the adhesive surface and the connecting surfaces, where the insulation film has at least one polymeric film having a thickness of 10 μm to 100 μm, at least one polymeric layer having a thickness of 5 μm to 80 μm and also a metal layer having a thickness of 10 nm to 1500 nm or a ceramic layer having a thickness of 10 nm to 1500 nm.

First claim

The invention claimed is:

1. A spacer for a multipane insulating glazing unit comprising at least a composite composed of:
a glass-fiber-reinforced, polymeric main body comprising:
two pane contact surfaces running parallel to each other,
an adhesive surface, and
a glazing interior surface,
wherein the pane contact surfaces and the adhesive surface are connected to each other directly or via connecting surfaces, and

an insulation film on the adhesive surface or on the adhesive surface and the connecting surfaces,
wherein the insulation film comprises:
at least one polymeric film having a thickness from 10 μm to 100 μm,
at least one polymeric layer having a thickness from 5 μm to 80 μm, and
at least two layers alternating with the at least one polymeric layer selected from the group consisting of at least two metal layers each having a thickness from 10 nm to 1500 nm and at least two ceramic layers each having a thickness from 10 nm to 1500 nm.

2. The spacer according to claim 1 , wherein the at least one polymeric film and the at least one polymeric layer are made from the same material.

3. The spacer according to claim 1 , wherein the insulation film has gas permeation of less than 0.001 g/(m 2 h).

4. The spacer according to claim 1 , wherein the composite has a PSI value less than 0.05 W/mK.

5. The spacer according to claim 1 , wherein the at least one polymeric film and/or the at least one polymeric layer include polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles, polymethyl acrylate, any copolymers thereof or any mixtures thereof.

6. The spacer according to claim 1 , wherein the at least two metal layers contain iron, aluminum, silver, copper, gold, chromium, any alloys thereof or any mixtures thereof.

7. The spacer according to claim 1 , wherein the at least two metal layers have a thickness from 10 nm to 400 nm.

8. The spacer according to claim 7 , wherein the at least two metal layers have a thickness from 10 nm to 200 nm.

9. The spacer according to claim 1 , wherein the at least two ceramic layers contain silicon oxides, silicon nitrides or mixtures of silicon oxides and silicon nitrides.

10. The spacer according to claim 1 , wherein the at least one polymeric layer has a thickness from 10 μm to 80 μm.

11. The spacer according to claim 1 , wherein the insulation film has 2 to 4 metal layers or ceramic layers.

12. The spacer according to claim 1 , wherein the insulation film has 1 to 4 polymeric layers.

13. The spacer according to claim 1 , wherein the main body has, along the adhesive surface and the glazing interior surface, a length or width from 5.5 mm to 8 mm.

14. The spacer according to claim 1 , wherein the main body has, along the pane contact surfaces, a length from 5 mm to 30 mm.

15. The spacer according to claim 1 , wherein the main body contains a desiccant, including at least one of silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated charcoal, silicates, bentonites, and zeolites.

16. The spacer according to claim 1 , wherein the main body contains at least one of polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene-polycarbonate (ABS/PC), styrene acrylonitrile (SAN), PET/PC, PBT/PC, and acrylonitrile butadiene styrene (ABS).

17. The spacer according to claim 16 , wherein the main body contains at least one copolymer of polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile styrene acrylester (ASA), acrylonitrile butadiene styrene-polycarbonate (ABS/PC), styrene acrylonitrile (SAN), PET/PC, PBT/PC, and acrylonitrile butadiene styrene (ABS).

18. An insulating glazing unit comprising:
at least two panes,
the spacer according to claim 1 surrounding the panes, and
an outer insulating layer.

19. A method comprising:
arranging the spacer according to claim 1 between a first glass pane and a second glass pane in a multipane insulating glazing unit.
