The Importance of Cladding Systems in Construction

In the world of construction, cladding is an essential element that often goes unnoticed by the untrained eye. However, its role in protecting structures from environmental elements and enhancing their aesthetics cannot be underestimated. In this blog post, we will delve into the world of cladding systems, exploring their significance, installation methods, and materials used.

Understanding Cladding Systems

Cladding Defined: Cladding is like the armor of a building. It shields the exterior of a structure, safeguarding it against the harsh forces of nature such as torrential rains, heavy winds, and more. Beyond its protective role, cladding also serves an aesthetic purpose by concealing the less attractive substrates or materials beneath.

Cladding Installation Systems

The installation of a cladding system is a crucial aspect of construction, and it varies depending on the materials used. There are three primary methods for installing cladding systems, each with its unique advantages and considerations.

1. Attached System

In the attached system, large cladding panels are directly affixed to the structural frame of the building. This method is particularly useful for erecting precast concrete and steel-stud frame structures with exterior finishes. The panels are lifted into place using cranes and secured to anchors at the edge of the slab.

Advantages of the Attached System:

  • Time-efficient, reducing on-site construction duration.
  • Enhanced insulation for exterior walls.
  • Protection of the structural frame against weather effects.

Challenges:

  • Design, approval, and manufacturing of panels can potentially cause project delays.
  • Thorough examination of the design is essential to avoid post-installation issues.

2. Curtain Wall System

The curtain wall system finds its place in large and multi-storeyed buildings. It shares similarities with the attached system but differs in the way panels are connected. Instead of anchors at slab edges, panels are attached to the structural frame using clip angles.

Key Features of the Curtain Wall System:

  • Utilizes a lightweight frame for easy handling and assembly.
  • Typically incorporates metal and glass cladding panels.
  • Streamlines design and manufacturing processes due to standard material combinations.

3. Infill System

The infill system stands out as the structural frame is exposed. Cladding panels are positioned between the columns of the structural frame, spanning from one slab level to another. Common materials used in this system include cast-in-place concrete panels, glass, and precast concrete.

Advantages of the Infill System:

  • Safer installation as cladding panels are placed from inside the building, minimizing risks to workers on scaffolding.
  • However, this system has weaker heat-insulating properties, leading to heat exchange between floor slabs and expansion/contraction of the structural frame.

Challenges:

  • Precise design and assembly are crucial due to non-uniform loads on structural elements over time.

Conclusion

In conclusion, cladding systems are more than just a cosmetic addition to buildings; they play a vital role in protecting structures from the elements and contributing to their overall aesthetics. Choosing the right installation method and materials is essential for a successful construction project. Whether it’s the attached system, curtain wall system, or infill system, each has its unique advantages and considerations that builders and designers must carefully weigh. By understanding these cladding systems, construction professionals can ensure the longevity, functionality, and visual appeal of their projects.
