An Introduction to Cladding Systems: What, Why and Environmental Impact

nitehawk-cinema-facade-003Wall cladding Singapore experts explain cladding as the visible, external finish of any home or building. These surfaces are either the walls or the roof. Another definition of cladding, as given by construction companies, is an external finish which is non-structural in nature, different from load-bearing construction. Cladding, however, offers significant support to the structural integrity by redistributing the external force applied by strong winds and feedback load on the structure. Wind is capable of triggering both negative and positive pressure (Bernoulli’s theorem), the cladding material must be engineered such that it’s stiff enough to withstand a blow and flexible to redirect excess pressure.

Advantages of Cladding System

  • Noise cancellation: Cladding offers an extra layer of protection to the external walls. The phenomenon of sound absorption depends on the density levels — highly dense, sound is kept out and conversely sound absorption is high. Cladding external surfaces using any material limits the rate of sound absorption and as a result audio insulation is offered.
  • Insulation: The principle is the similar to sound, but here the added layer protects from internal heat fluctuations. The external façade behaves like a heat shield during the summer, blocking the walls from absorbing excess heat and dissipating it indoors.
  • Protection against weather damage: An external layer of cladding is more effective than a layer of coating to protect the walls.
  • Appeal: Think of cladding as a new hair cut — it changes the appearance of the house, a complete makeover. The value of the house increases when you invest in external cladding. You can choose from stone, timber, metal and PVC.

Points to consider before investing in cladding

As the material choices offered are many, picking the ideal option will depend on the following factors:

  • Is the chosen material easy to install?
  • How expensive is it?
  • How will it affect the external appeal and appearance?
  • Its durability and strength

Environmental impact of cladding

When a construction begins, it environmental impact is often ignored. As long as it looks appealing, its hazardous nature is best ignored. This lack of environmental responsibility has culminated to trigger global warming (like the widespread use of reflective surfaces that created hot pockets in the atmosphere). To make the cladding sustainable, choose eco-friendly options and educate yourself on safe disposal practices.
