What is cladding and why it used

Cladding is the application of one material over another to provide a skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. ( Source: Wikipedia )

In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. … Cladding may also be a control element for noise, either entering or escaping. Cladding can become a fire risk by design or material.

WHAT IS CLADDING?

  • Cladding is a type of “skin” or extra layer on the outside of a building.
  • It can be attached to a building’s framework or an intermediate layer of battens or spacers.

CLADDING USES

It is mainly used to stop wind and rain from entering the building.

  • Cladding can also provide sound and thermal insulation as well as fire resistance.
  • It is often used to make a building’s exterior look more attractive.

WHAT IS CLADDING MADE FROM?

  • Wood, metal, brick, vinyl, composite materials that can include aluminum, wood, blends of cement and recycled polystyrene, wheat/rice straw fibers.

IS CLADDING FIRE RESISTANT?

  • Excellent fire resistance cladding: brick.
  • High fire resistance cladding: planks or weatherboards made from fibre cement or steel.
  • Good fire resistance cladding: aluminium, reconstituted timber products.
  • Poor fire resistance cladding: timber weatherboards, plywood sheets.

WHAT ARE THE ISSUES WITH ALUMINIUM COMPOSITE CLADDING PANELS?

  • There is potential for fire to spread quickly upwards in a building if inappropriate products are used.
  • The panels consist of two aluminum faces and a core material such as polyethylene, a mineral-based material, or a combination of both.
  • Panels are between 3mm and 5mm thick.
  • They may look similar on the outside, but their core materials may differ and affect their fire resistance.
  • Panels with a higher proportion mineral core are considered to withstand fire better, but can still be considered combustible.
