The key role of Jacketing is to control penetration of weather element and ingress of water. It also provides mechanical strength to the insulation the jacket also serves to establish the system emissivity and appearance.
While selecting insulation jacketing must consider the mechanical, thermal, chemical and moisture conditions of the installation. Cost and aesthetical requirement also has to be considered.
Insulation is covered by metal jacketing like Aluminum, Stainless Steel, Coated steel, Aluminized steel, Galvalume steel, and Zinc galvanized steel. Metal jackets come lined with bonded polykraft paper or polysurlyn.
Aluminum sheet are widely used in fabricating metal Insulation jacketing. Aluminum is light weight, flexible to fabricate easily at site and has good resistance to corrosion. Apart from this Aluminum has many characteristics due to which it is commonly used as a insulation jacketing metal.

Aluminum sheet are widely used in fabricating metal Insulation jacketing. Aluminum is light weight and having good resistance to corrosion.
The term corrugated, describing a series of parallel ridges or furrows. There are two types of corrugation, circular and trapezoidal. Corrugation describe in terms of, pitch and depth, It is important that depth and the pitch to be quite uniform to be easily stackable and to overlap neatly on joints

Aluminum Stucco sheet has rugged surface which reduce light reflection and glare, due to its embossed pattern which reduces vibrations’ it provides additional mechanical strength to the sheet
Aluminum sheet coated with moisture retarders: Layer of plastic film or other material applied to the inner side of metal jacketing to inhibit jacket corrosion by interfering with the formation of a galvanic cell between the dissimilar metal of the pipe and jacket or by preventing crevice corrosion.
Aluminum with Poly Kraft Coating: A multilayer composite film used as s moisture retarder on metal jacketing consisting of at least one layer of minimum 40 LB Kraft Paper and one or more layers of plastic film, usually polyethylene at a minimum thickness of 1.5 mils.
Aluminum Sheet coated with Polysurlyn : A multilayer film used as a moisture retarder on jacketing consisting of at least one layer of acid copolymer surlyn and one or more layers of other polymers, usually polyethylene.

Stainless steel are notable for their corrosion resistance, Which increases with increasing chromium content. Addition of Molybdenum increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. Thus there are numerous grade of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure.
Stainless steels resistance to corrosion and staining, low maintenance, and familiar luster make it an ideal material for many applications where both the strength of steel and corrosion resistance is required.*
Normally available in two grades
Aluminum foil is used
1) As a Vapor Barrier
2) For the Corrosion Protection over SS Surface.
Vapor Barrier: In cold Insulation Process to avoid sweating or condensation. Aluminum foil is used in between insulation and jacketing application as a vapour barrier.
Corrosion Protection over SS Surface: Aluminum Foil is applied before Insulation over the surface of Stainless steel vessel / pipes to avoid corrosion. SS Surface when directly come in contact to mineral it cause corrosive action to avoid this foil is applied.

Other than metals, thermoplastic and flexible fabrics are also important jacketing material.
Thermoplastic jackets are generally not preferred due to their poor resistance of fire, how ever wide variety of fabric made from Fiber Glass & Ceramic with special coatings are used in different types of jacketing over insulation.
The thin, continous and multi fiber filaments are process through reinforcment and woven to form fiberglass fabric.
This fiber glass fabric is light weight and versatile material with high heat resistance.
