Insulating panels or plates are formed along their opposite longitudinal edges with a cylindrically segmental projection and a cylindrically segmental groove receiving the projection, both of these formations being preferably formed as extruded polyvinyl chloride shells. The arc length of the groove

Insulating panels or plates are formed along their opposite longitudinal edges with a cylindrically segmental projection and a cylindrically segmental groove receiving the projection, both of these formations being preferably formed as extruded polyvinyl chloride shells. The arc length of the groove is greater than 180°but less than that of the projection so that the plates can be interfitted and angularly offset to fit around a vessel, the angular adjustability allowing the plates to be accommodated to greater and lesser curvatures of the vessel.

An insulation for a vessel having a curved outer wall and adapted to form a sheath hugging said wall, said insulation comprising a multiplicity of elongated plates having opposite longitudinal edges, each of said plates being formed with a projection along one of said edges extending the full length

An insulation for a vessel having a curved outer wall and adapted to form a sheath hugging said wall, said insulation comprising a multiplicity of elongated plates having opposite longitudinal edges, each of said plates being formed with a projection along one of said edges extending the full length thereof and with a groove along the opposite edge extending the full length thereof and shaped to receive such projection, said groove and said projection being each of cylindrical segmented configuration with said groove having an arc length greater than 180°and said projection having an arc length greater than that of said groove such that more than a semicircular arc of each projection is receivable in a groove of an adjoining plate, adjoining plates being laterally retained to one another by the formfit interengagement between projection and groove and being angularly displaced relative to one another about the centers of curvature of the respective projections at varying angles corresponding to the radius of curvature of said wall to enable a sheath of said plates to closely surround said vessel, each of said plates comprising a body of foamed thermally insulating material, the interfitting grooves and projections constituting the sole means for laterally retaining the plates together into a sheath, whereby no other means is required to retain the plates together against lateral separation.
