Abstract
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.degree. 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.
