A vacuum insulating panel comprise a first sheet of a flexible material, a second sheet of a flexible material and a bridging element of a flexible material extending in a generally rectilinear waveform between the first and the second sheets. The bridging element and the sheets define therebetween a plurality of separate generally rectilinear evacuated compartments containing a self-supporting insulating element. The bridging element comprise first flat regions extending along the inside face of the first sheet, second flat regions extending along the inside face of the second sheet, and connecting regions extending between the first and second flat regions, There are seals between the flat regions of the bridging element and the inside face of the sheets. If one compartment is punctured only that compartment is affected. The seals prevent loss of vacuum in adjacent compartments.

1. A vacuum insulating panel comprising: a first sheet of a flexible material,a second sheet of a flexible material, a bridging element of a flexible material extending in a generally rectilinear waveform between the first and the second sheet,the bridging element and the sheets defining therebetween a plurality of separate generally rectilinear evacuated compartments containing a self-supporting insulating element,the bridging element comprising first flat regions extending along the inside face of the first sheet, second flat regions extending along the inside face of the second sheet, and connecting regions extending between the first and second flat regions, and for each compartment, seals between the flat regions of the bridging element and the inside face of the respective first or second sheet, wherein for each compartment there are at least two spaced apart seals between the bridging element and the respective first or second sheet. 2. The vacuum insulating panel as claimed in claim 1 wherein a seal is located adjacent to each corner of the bridging element in contact with the sheet. 3. The vacuum insulating panel as claimed in claim 1 wherein the panel comprises at least two panel parts which are separated by a fixing gap. 4. The vacuum insulating panel as claimed in claim 3 wherein the gap extends longitudinally along the length of the panel. 5. The vacuum insulating panel as claimed in claim 3 wherein the vacuum insulating panel comprises a filler for filling the gap. 6. The vacuum insulating panel as claimed in claim 3 wherein the vacuum insulating panel comprises at least two spaced apart fixing gaps. 7. The vacuum insulating panel as claimed in claim 1 wherein the bridging element is pre-formed to a shape. 8. The vacuum insulating panel as claimed in claim 7 wherein the bridging element is of a polyethylene film. 9. The vacuum insulating panel as claimed in claim 1 wherein the bridging element comprises a single layer. 10. The vacuum insulating panel as claimed in claim 1 wherein the bridging element comprises a plurality of layers. 11. The vacuum insulating panel as claimed in claim 10 wherein the bridging element comprises a barrier layer, a first bonding layer on one face of the barrier layer for bonding to the first sheet, and a second bonding layer on an opposite face of the barrier layer for bonding to the second sheet. 12. The vacuum insulating panel as claimed in claim 11 wherein the barrier layer of the bridging element comprises a metal or metallised material. 13. The vacuum insulating panel as claimed in claim 11 wherein the first outer sheet comprises an outer barrier layer and an inner bonding layer for bonding to the first bonding layer of the bridging element. 14. The vacuum insulating panel as claimed in claim 11 wherein the second sheet comprises an outer barrier layer and an inner bonding layer for bonding to the second bonding layer of the bridging element. 15. The vacuum insulating panel as claimed in claim 13 wherein the barrier layer of the first and/or second sheet is of a metal or metallised material. 16. The vacuum insulating panel as claimed in claim 11 wherein the or each barrier layer is of aluminum foil. 17. The vacuum insulating panel as claimed in claim 11 wherein the or each barrier layer is of stainless steel foil. 18. The vacuum insulating panel as claimed in claim 11 wherein the barrier layer is of metallised polymeric film. 19. The vacuum insulating panel as claimed in claim 1 wherein the first and second sheets are of the same material. 20. The vacuum insulating panel as claimed in claim 1 wherein the bridging element is of the same material as the first and/or second sheet. 21. The vacuum insulating panel as claimed in claim 1 wherein the insulating element comprises a plurality of insulation pieces and a binder. 22. The vacuum insulating panel as claimed in claim 1 wherein the insulating element comprises an insulating foam material. 23. A vacuum insulating panel comprising: a first sheet of a flexible material,a second sheet of a flexible material, a bridging element of a flexible material extending in a generally rectilinear waveform between the first and the second sheet,the bridging element and the sheets defining therebetween a plurality of separate generally rectilinear evacuated compartments containing a self-supporting insulating element,the bridging element comprising first flat regions extending along the inside face of the first sheet, second flat regions extending along the inside face of the second sheet, and connecting regions extending between the first and second flat regions, and for each compartment, seals between the flat regions of the bridging element and the inside face of the respective first sheet and the second sheet wherein for each compartment there are at least two spaced apart seals between the bridging element and the respective first sheet and second sheet.
