A vacuum insulating panel comprise a first sheet 3 of a flexible material, a second sheet 4 of a flexible material and a bridging element 1 of a flexible material extending in a generally rectilinear waveform between the first and the second sheets 3,4. The bridging element 1 and the sheets 3,4 define therebetween a plurality of separate generally rectilinear evacuated compartments containing a self-supporting insulating element 5. The bridging element 1 comprise first flat regions 7 extending along the inside face of the first sheet 3, second flat regions 8 extending along the inside face of the second sheet 4, and connecting regions 9 extending between the first and second flat regions 7,8. There are seals 10 between the flat regions of the bridging element 1 and the inside face of the sheets 3,4. If one compartment is punctured only the compartment is affected. The seals prevent loss of vacuum in adjacent compartments. |
