ZEROPERM® Tapes - Two types of tapes are available to complete the field installation. Both use a high quality, acrylic adhesive with excellent cold weather performance. ZEROPERM® A Tape has a kraft release liner and is typically used for sealing longitudinal and circumferential laps. ZEROPERM® Self-Wound Tape has no liner, is used on valves and fittings.

ZEROPERM® vapor barrier acrylic tapes are required for use with Polyguard Products ZEROPERM® Vapor Barrier membrane to seal butt joints and longitudinal joints and for use on valves and fittings. Made from the same material as the ZEROPERM® Vapor Barrier, the tapes maintain an absolute “zero perm” barrier that provides maximum protection for all types of insulations used in below ambient, sub-freezing and cryogenic applications on duct, pipe, or vessel systems.

ZERO-PERM® Tapes are used as part of the ZEROPERM® Vapor Barrier System on cold pipe applications either between layers of insulation on sub-freezing projects like LNG piping, or as the outer vapor-barrier jacket on ammonia, brine or glycol systems under mechanical jacketing, either metal or PVC. ZEROPERM® can also be used on chilled water systems replacing ASJ and PVDC jacketing either left exposed or under a protective metal or PVC jacket.
