What is Cladding in construction?

Cladding refers to any material which is used to cover the primary structure of a building. It acts as a non-structural system that protects the roof or exterior walls from rain, sunlight, and other environmental conditions. Cladding adds one more layer to the external wall or roof. The cladding system consists of an outer weather protective layer, screen, or fillers attached with the help of brackets, gaskets, flashing, sealants, and others. Cladding does more than just serve as a protective agent; it also enhances the beauty of the exterior wall by playing with different materials, colors, textures, and designs. It looks aesthetically pleasing when it is ornamented well.

Selecting a good cladding material is necessary because rain and wind can cause negative and positive impacts on the cladding. Therefore, it has to be strong enough to resist all the load and protect the inner part of the wall. Any material can be used for cladding, like wood, metal, stone, vinyl, composites made of aluminium, wood, cement-wood mixtures, wheat-and-rice-straw fibers, and recycled polystyrene, but the cladding must be water-resistant because its main purpose is to keep water penetration away from the structure.

Purpose of Cladding

  1. Maintain careful control over the building’s atmosphere.
  2. Maintain the structure’s security against outside threats and circumstances.
  3. Maintain privacy and security inside the structure.
  4. Provide thermal insulation and noise reduction.
  5. They are utilised as ornamental components to enhance the appearance of the outer façade.
  6. Keep the fire from spreading across the structure.
  7. Construct an airtight building envelope.
  8. Internal circulation, mobility, natural light, and ventilation are all possible.

Properties of Cladding Materials

In a building, cladding is done to enhance the aesthetic appeal of walls, kitchen slabs, stairs, roofs, ceilings, etc.

The desirable properties of a cladding material are:

  • It should be impermeable.
  • It should be available in attractive colors and shades.
  • It should keep its color for a long time.
  • It should be heat and fire-resistant.
  • It should be capable of hiding inferior materials and poor workmanship.
  • It should be light in weight.
  • It should be possible to fix it to the wall with suitable additives or mortar.
