Abstract
An insulation system for pipes which includes a segment of insulation which is split along its length for application to the pipe, and which is sealed against itself around the pipe by a flap overlapping the slit and extending along the length of the segment. The inside surface of the flap is provided with a strip of pressure sensitive adhesive which extends to the outer edge of the flap and which seals the flap against the outer surface of the insulation segment. A release liner is provided in contact with the adhesive layer. The release liner extends from the outer edge of the flap inwardly to and beyond the inner edge of the strip of adhesive. The release liner overlies a non-adhesive strip adjacent the adhesive strip a distance sufficient to allow the release liner to be grasped by a gloved hand for removal thereof in extreme weather conditions.
