External jacket or cladding for duct sections providing thermal insulation, mechanical protection, and environmental resistance in industrial ventilation systems.
An external jacket or cladding is a protective outer layer applied to duct sections in industrial ventilation and HVAC systems. It serves multiple functions including thermal insulation to maintain temperature control, mechanical protection against physical damage, corrosion resistance, and containment of internal insulation materials. Typically constructed from durable materials like aluminum, galvanized steel, or specialized polymers, it forms a sealed barrier that enhances system efficiency, safety, and longevity by preventing heat loss/gain, condensation, and environmental degradation.

The primary purposes are thermal insulation to maintain temperature control, mechanical protection against damage, prevention of condensation through vapor barriers, and extending duct system lifespan by providing environmental resistance.
Material selection depends on environmental conditions: aluminum for general applications, galvanized steel for mechanical durability, stainless steel for corrosive environments, and polymer composites for chemical resistance. Consider temperature range, humidity, chemical exposure, and required fire ratings.
Regular visual inspections for damage, cleaning to remove contaminants, checking seal integrity at joints, and prompt repair of any punctures or corrosion spots. In harsh environments, more frequent inspections may be necessary.
