Metal Jacketing and Fittings

Johns Manville offers aluminum and stainless steel jacketing, sheets, and elbows to protect thermal insulation used in a variety of applications. Our products are recognized in the industry under the brand names of Pabco and Childers Metals. In addition to metal jacketing, we also distribute stainless steel and aluminum strapping and seals, as well as installation tools.

Aluminum Roll 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.

Aluminum Roll 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.

Stainless Steel Roll Jacketing is manufactured from T-304 and T-316 prime grade Stainless Steels. These alloys comply with ASTM A-240 and are supplied with a dull finish for reduced glare.

Stainless Steel Roll Jacketing is manufactured from T-304 and T-316 prime grade Stainless Steels. These alloys comply with ASTM A-240 and are supplied with a dull finish for reduced glare. The yield strength is 30,000-45,000 PSI, and the tensile strength is 75,000-110,000 PSI. These alloys are of a special soft-annealed temper, for ease in fabrication. T-304 is normally used in all except the most corrosive areas, where T-316 is recommended. The melt point of our 300 Series Stainless Steel is 2500°F, making it an excellent solution for fire protection.

Painted Aluminum Roll Jacketing has a factory-applied, baked-on finish of highly durable hard film acrylic or polyester paint on the exterior surface. This finish provides improved aesthetics, color-coding, increased emittance, and improved corrosion protection for the aluminum jacketing.

Painted Aluminum Roll Jacketing has a factory-applied, baked-on finish of highly durable hard film acrylic or polyester paint on the exterior surface. This finish provides improved aesthetics, color-coding, increased emittance, and improved corrosion protection for the aluminum jacketing. Painted Aluminum Roll Jacketing can be used on pipes, tanks, and equipment insulation systems. The special paints used on this jacketing are chalk and fade resistant. They exhibit better resistance to oxidation and to the effects of various corrosive environments than bare aluminum jacketing. This painted surface also resists water and fingerprint staining.

Muffl-Jac sound barrier jacketing is a sound barrier jacketing used with both fibrous and closed-cell insulation materials as a path control form of acoustic treatment.

Muffl-Jac??sound barrier jacketing is a sound barrier jacketing used with both fibrous and closed-cell insulation materials as a path control form of acoustic treatment. It is made from a special high density, composite film laminated to 0.020” aluminum, using a viscoelastic film adhesive. It simultaneously absorbs, dampens, blocks, and isolates sounds, reducing noise levels radiated by piping and equipment. Standard 1 lb Muffl-Jac sound barrier jacketing is available in 0.020” aluminum with a stucco embossed finish. Rolls are 36" wide and 36' length (108 sq. ft.).
