What is a common use of asbestos in construction?

Asbestos was commonly used in construction primarily for its excellent insulating properties. It is a mineral that is highly resistant to heat and fire, making it an ideal choice for insulating materials used in buildings. In the context of insulation, asbestos was often found in pipe insulation, thermal insulation for boilers, and other heat-resistant applications.

While asbestos may have been present in various building materials, including wall decoration and flooring, its significant and widespread application as insulation highlights its functional benefits in protecting buildings from heat and minimizing energy loss. The other choices, while they could involve materials that may contain asbestos, do not directly represent its primary and most recognized use in construction.
