Insulrap 30-SJ NG offers fiberglass scrim reinforcement embedded in the laminate using a process that minimizes the scrim profile providing extra strength, durability and enhanced lap adhesion. It's part of the "Next Generation" of self-healing vapor barrier membranes used as a moisture and vapor retarder under mechanical jacketing on insulated piping systems used in ammonia refrigeration, oil and gas, LNG, cryogenic and chemical processing applications. I-30-SJ NG is comprised of a white, scrim reinforced finish that will stretch and flex to accomodate movement of the substrate. This 30 mil thick vapor barrier composite membrane consists of a tough polymer/foil laminate film coated with a layer of rubberized-asphalt specially formulated for use in these applications. The "peel and stick" product consists of a built-in disposable silicone-coated release liner to make application quick and easy. I-30-SJ NG offers exceptional longitudinal stability, self-healing, and zero perms making it the obvious choice of below ambient systems.
