Types of Curtain Walls:

1. Unitized or Modular Systems:

Unitized or Modular Systems

At the plant site, key components are arranged and glassed to form a single unit.

It excludes the installation of a single unit on its own.

Large, tall buildings typically choose this style of curtain wall.

Unitized systems also have the advantage of being quicker to build and more labour-efficient.

But shipping costs are frequently expensive because a large curtain walls unit must be transported and escorted safely to the main construction site.

2. Stick Systems:

Stick Systems

Stick systems are preferred when developing tiny areas and structures.

It entails setting up and putting in place the smaller curtain wall units in the area where this wall system is installed.

But, stick systems’ time-consuming and labour expenses are also significantly higher than those of unitized systems.

However, shipping costs are relatively less expensive.

Advantages of Curtain Wall:

1. Visual impact:

It is undeniable that a curtain wall offers remarkable and breathtaking visuals to the building’s architecture.

2. Strong and long-lasting construction:

Curtain walls are often made of high-quality, lightweight aluminium that is sturdy and robust.

3. Flexibility in design:

Curtain walls offer flexibility in design, which is a wonderful additional benefit.

4. Less Expensive to Build:

Since the Curtain Wall System is made of lightweight materials, it significantly lowers the cost to build.

5. Supports its weight:

Technically, the curtain walls are made to support their weight without requiring assistance from the structure.

6. Reduces power consumption:

Curtain walls could end up being a cost-effective investment due to their huge reduction in energy usage.

7. Protection from Fire:

The curtain walls separating the building’s divisions act as a fire-resistant barrier.

8. Eliminates water and pollution penetration:

When it rains, the curtain walls keep water from penetrating.

9. Protection from winds:

Curtain walls give the structure of the building resistance and defence against the wind.

10. Protection from extreme weather:

The curtain walls protect against all types of extreme weather including heavy precipitation in the form of snowfall or rain.

11. Positive effect on the interior of the building:

More great lighting inside the building is made possible by the curtain walls, which improves the working environment.

Disadvantages of Curtain Wall:

  1. To maximize its use, curtain walls will require greater upkeep, this implies that frequent cleaning of the frames and glass may be required.
  2. Due to the difficulty of installing these panels and the fact that they must be fastened from the outside, inclement weather frequently causes delays for the building crew.
