Abstract
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.
