JM Aluminum Jacketing is the premier protective outer surface for mechanical insulation systems, including pipes, vessels, and equipment. It helps protect the insulation and underlying pipe/vessel from physical damage, UV exposure, corrosive environments, and water. JM's Aluminum jacketing (also called cladding) is available in smooth, stucco embossed, and 3/16" corrugated (cross-crimped) finishes. For larger surfaces, box-rib and deep corrugated sheets are also available. Our Aluminum Jacketing has a bare outer surface and comes standard with a 3-mil thick polyfilm moisture barrier heat-laminated to the interior surface to help prevent corrosion of the jacketing and the underlying metal pipe, vessel, or equipment.
