In balloon framing, what is a common material used?

In balloon framing, wood is the common material used primarily due to its lightweight, structural integrity, and availability. This construction technique involves long, vertical wooden studs that run from the foundation to the roof, creating a framework that supports the building. Wood allows for the rapid assembly of walls and offers good flexibility, which is beneficial for expanding or modifying structures. Additionally, wood has good insulation properties, making it suitable for residential construction. While other materials like steel, concrete, and brick are used in various types of construction, they are not characteristic of the traditional balloon framing method.
