Which type of asbestos is most commonly used in building materials?

Chrysotile, often referred to as white asbestos, is the most commonly used type of asbestos in building materials. Its prevalence stems from its desirable properties, including flexibility, chemical resistance, and high tensile strength, which make it suitable for a wide range of applications. Chrysotile is widely found in products such as roofing materials, floor tiles, insulation, and various fireproofing materials.

In many cases, chrysotile was favored over other types of asbestos due to its relatively lower toxicity compared to the other varieties, although all forms of asbestos pose health risks when disturbed. This widespread use makes it the most significant type of asbestos in construction and industry, leading to its frequent identification in buildings constructed before the 1980s.
