Cladding vs. Lagging: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on November 22, 2023
Cladding refers to a covering or coating on a structure, while lagging is insulation material used on pipes or boilers.

Key Differences

Cladding involves the application of one material over another to provide a protective or aesthetic layer, while lagging specifically refers to the insulation and protective material wrapped around pipes, boilers, or ductwork.
In construction, cladding is used for weather resistance and aesthetic appeal of buildings; lagging, on the other hand, is employed primarily for its thermal insulation properties in industrial settings.
While cladding can be made of wood, metal, brick, or composite materials, lagging is typically composed of materials like mineral wool, fiberglass, or foam.
Cladding enhances the appearance and can also provide soundproofing benefits; lagging is focused on reducing heat loss and controlling surface temperatures.
Maintenance requirements for cladding depend on the materials used and environmental factors, whereas for lagging, the focus is on the integrity of insulation and safety standards in industrial environments.
