ZEROPERM® A Tape is available to complete installation in the field. It uses 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. It is available in 2” and 3” wide rolls. Made from the same material as the ZEROPERM® Vapor Barrier, the tape maintains 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.

ZEROPERM® 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.
