Cross-Flo Jacketing

Johns Manville's Metal Jacketing is the premier protective outer surface for industrial and mechanical insulation systems including pipes, vessels and equipment. It protects the insulation and underlying pipe/vessel from physical damage, UV exposure, corrosive atmospheres and water.

Johns Manville Cross-Flo® Jacketing is a unique innovation for ambient and hot systems, designed to help mitigate the potential for corrosion under insulation (CUI). It has an embossed pattern engineered to promote cross-directional flow (CDF), providing a path for unwanted liquid to more rapidly reach the low point of a system and exit the jacketing through a weep hole or drainage port. In addition to numerous technical benefits, Cross-Flo Jacketing has a distinctive aesthetic appearance and comes standard with a 3-mil thick polyfilm moisture barrier heat laminated to the interior surface to provide additional protection against corrosion.
