Nashua ASJ All-Service Jacketing Tape is a tape with a white Kraft paper, scrim, and metal foil backing coated with an acrylic based adhesive. Used as a permanent closure system and vapor barrier seal on ASJ-faced duct and pipe systems and for sealing insulation and repairing in cooler / refrigeration applications. The tape's backing gives it high strength and makes it tear resistant. It is also easy to apply and matches well with ASJ insulation. The tape is tri-directional fiberglass reinforced and has a high tack adhesive. Nashua ASJ is mold resistant and is non-solvent for less odor. It also has low VOC content and can contribute toward satisfying EQ Credit 4.1 (Low Emitting Materials) under LEED®.
