Curtain wall facade - Types, components, and the new digital way of custom parts manufacturing

Sudarshan Naik

The facade industry is booming in India. The rise in spending power of the people, especially in Tier 2 and Tier 3 cities, has led to them investing in better aesthetics, look, and feel of buildings. According to Grand View Research, the Indian facade market is pegged at Rs. 15000 crore with expected annual growth rate of 20% between 2019 and 2025.

Various types of facades are used for commercial buildings like steel facade, panel frame facade, curtain wall facade, clay facade, aluminium composite facade, precast concrete facade, etc. Out of these facades, curtain wall facades are one of the most common types of facade.

As the demand for facade rises across India, the need for custom components that are used in making facades will also rise. In the normal course, facade manufacturers order custom parts through the traditional process of sourcing and procurement from suppliers, which is often inefficient owing to lack of transparency across the value chain.

karkhana.io has developed an alternative way of getting components manufactured, which brings efficiency and speed to the sourcing and procurement process. Karkhana.io has developed an ecosystem of suppliers and customers, enabled through the digital platform, app.karkhana.io. The customers can send requirements of facade components to karkhana.io‘s digital platform. The platform matches the requirements to the right supplier and takes the responsibility of managing the project, right from raw material procurement till the delivery of the product. This alternative way allows customers to focus on designing the aesthetics of facades, marketing, and sales of facade.

In this blog, we take a look at one of the fastest growing facade segment: curtain wall facade, types of curtain wall facades, and components of curtain wall facade.

What is curtain wall facade?

A curtain wall is a thin, lightweight and usually aluminum framed wall which forms the outer covering of a building. Curtain wall is non-structural i.e. they only carry their own weight and doesn’t carry floor or roof loads of the building.

Types of curtain wall facade

The types of curtain wall facade includes

  1. Stick or framed systems
  2. Unitised system
  3. Ladder system
  4. Rainscreen principle

Components of curtain wall facade

The components of curtain wall facade are:

Mullion and Transom

A mullion is a vertical beam that is used to divide window glazing into smaller units. They can provide structural support to window arch.

A transom is a horizontal beam that is used to divide window glazing into different sections.

Brackets

Mullions are attached to the building with brackets at slab edges spanning 5-7m each. Mullions above and below are attached via internal sleeves.  Transoms are fitted to the mullions at predetermined points via brackets. And then, infill panels are fitted into rectangular openings created by mullions and transoms. The infill panel is typically a fixed glass, but can also be a combination of composite aluminum sheet, open sashes or stone.
