Curtain Walls: A Marvel of Architecture

Introduction

The use of curtain walls has completely changed how buildings are created and planned, revolutionizing the field of architecture. These thin, non-structural outside wall solutions have improved structural integrity, improved energy efficiency, and improved aesthetics.

What are Curtain Walls?

Curtain walls are vertical building envelope systems that cover a building's exterior from the outside. Curtain walls, as opposed to conventional load-bearing walls, are made to support only their own weight and transfer any external stresses to the primary structure of the building. Usually made of lightweight materials like glass, aluminum, or steel frames, they provide long stretches of unbroken glazing.

Components and Features

A curtain wall is made up of several essential parts that come together to provide a practical and aesthetically pleasing building envelope:

Framework: The curtain wall's framework serves as its skeleton and a source of structural support. It is typically composed of steel or aluminum and is intended to withstand pressure from the wind, earthquakes, and other external forces.

The glass panels that cover the curtain wall framework are referred to as glazing. Depending on the particular needs of the building, it might have different thickness, transparency, and insulating qualities.

Spandrels: To hide structural components, mechanical systems, or floor slabs, opaque or non-transparent panels called spandrels are inserted between glass panels. They aid in consistent appearance creation and interior concealment.

Sealants: Sealants are used to cinch together glass panels and the framework. They are vital to maintaining the curtain wall's weather resistance by limiting air and water entry.
