1. A pipe insulation sleeve assembly which comprises:

  • (a) an elongated, hollow, cylindrically shaped tubular section of insulating material having a longitudinally extending access slit between an inner surface and an outer surface of said sleeve, said access slit defining a first side and a second side of said outer surface adjacent said access slit;

    (b) a closure system for maintaining said access slit in a closed position, said closure system comprising an adhesive carrier integrally secured to a first side of said outer surface, extending between said first and second sides of said outer surface and across said access slit, a layer of adhesive disposed on at least a portion of said carrier and capable of contacting said outer surface second side;

    (c) a release liner removably disposed on a first area of said adhesive layer, while a second area of said adhesive layer remains exposed;

    such that said exposed second area of adhesive layer affords an initial bond between said carrier and said outer surface second side of said access slit;

    said first and second areas of exposed adhesive layer combine to afford a second bond between said carrier and said outer surface second side of said access slit when said release liner is removed.
