A packaged multilayer insulating product where at least one insulating product plate 10A-D comprises at least one first film 12 and at least one central element 14 which comprises corrugations spreading according to direction of propagation X with a pitch P and amplitude A wherein the corrugations connect to the at least one first film 12. The packing for the packaged insulating product holds the at least one plate in a state of compression in the direction of propagation of the corrugations such that the pitch P in the stressed state is lower than in the unstressed state and amplitude A in the compressed state is higher than in the uncompressed state. The corrugations may have a zigzag profile and delimit a planar outer face which is continuous and rectilinear. The packing may comprise an envelope or banding and the packet may comprise a rod or wire 60 passing through the at least one plate 10 according to the direction of propagation of the corrugations and held the two ends 64 or the rod or wire 60 against the sides of the plate extending transversally to the direction of propagation of the corrugations. Also included are a method of compressing said insulating product plate 10 and equipment for compressing product plate 10 which may include components which will exert pressure on the outer faces of the plate parallel to the film to allow control of the spacing of the outer faces from one another.
