An adhesive tape construction adapted for use in an insulation system for pipes. The tape is applied to the insulation tube to seal the split so that the insulation can be secured in a closed position. The tape construction includes outer release liners which protect corresponding layers of conventional tacky adhesive utilized to secure the tape to the article. A central release liner is utilized to separate layers of the primary adhesive which, when joined, will seal the insulation tube. The primary adhesive has a chemical composition which gives it an affinity only for a similarly coated surface. The primary adhesive layers are preferably coated directly on the inner surfaces of the tacky adhesive. When using the tape construction to seal an insulation tube, the tape is first applied to the overlap flap of the insulation jacket by removing the outer release liners and applying the respective tacky adhesive surfaces to the mating surfaces of the flap. In this manner the insulation tube can be stored or shipped without damage. Upon application of the insulation tube, the flap is opened by removing the central release liner and mounting the insulation on the pipe. Thereafter, the insulation can be permanently sealed by joining the exposed surfaces of the primary adhesive. Since the primary adhesive will adhere only to itself, the insulation tube may be opened and closed several times before permanent application.
