Asbestos is a group of naturally occurring fibrous minerals with a distinctive set of properties that set it apart. These minerals, comprising of tiny, microscopic fibers, are known for their strength, resistance to heat, and impressive fire resistance. So, when the question, “What is asbestos?” is raised, it could be described as a kind of super-material that has been employed for its valuable properties in a myriad of industrial applications for centuries, with its usage significantly expanding from the 1950s onwards.
Digging deeper into its history, it’s worth noting that the use of asbestos isn’t a product of modern technology. Ancient civilizations were known to take advantage of its unique characteristics. However, the material’s true commercial potential was realized in the mid-20th century. A time when the industrial boom was in full swing, and there was an increasing demand for cost-effective materials that could stand the test of time. Asbestos perfectly fit this bill. Its durability made it not only cost-effective but also a long-term investment, which subsequently led to its widespread use and prominence within the industry.
Asbestos has been used since Ancient Times
In addition to its strength and resistance to heat and fire, asbestos has an excellent insulating capacity. This property made it an ideal choice for insulation in buildings, ships, and other structures, providing them with excellent thermal resistance. It was used extensively in the construction industry for fireproofing, with its asbestos-containing materials significantly enhancing the buildings’ resilience against fires.
While asbestos offered many advantages from an industrial perspective, the story is far from perfect. As later research would show, asbestos poses severe health risks, leading to a dramatic shift in its usage and regulations. But that’s a different aspect of the ‘what is asbestos’ query that warrants an in-depth discussion in itself.
Overall, the essence of ‘what is asbestos’ is encapsulated in its unique physical and chemical properties, its vast historical and industrial usage, and the subsequent understanding of its potential health risks. Asbestos, once considered an invaluable resource, now presents a complex dichotomy of industrial utility and health concerns.
What is Asbestos? Identifying its Qualities

Asbestos is a term used to describe a set of naturally occurring minerals made up of microscopic fibers. It is fire-resistant, heat-resistant and very durable, making it an ideal material for insulation and fireproofing. Although asbestos has been used in industrial applications since ancient times, its widespread use began in the 1950s when asbestos was deemed cost-effective and very durable.
Asbestos building materials can be found in many places in our homes, including insulation, drywall and flooring. Insulation around pipes, vents and furnace ducts often contains asbestos fibers which are released into the air when disturbed. Floor tiles, mastic, siding, pop-corn ceiling texture, just to name a few are some of many building materials that can contain asbestos fibers.
As asbestos became increasingly popular in the 1950s, it wasn’t until decades later when the health risks associated with asbestos exposure were fully understood and the Environmental Protection Agency (EPA) decided to step in.
Exposure to asbestos fibers can cause serious illnesses such as asbestosis, mesothelioma, and lung cancer. Even more concerning is that asbestos-related diseases can take anywhere from 10-40 years to emerge.
