Asbestos is a fibrous mineral that was commonly used in building materials such as insulation, floor tiles, and roofing. Asbestos was popular in the construction industry because of its heat-resistant properties and durability.

However, we now know that exposure to asbestos can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. Asbestos is made up of microscopic fibers that, when inhaled, can become embedded in lung tissue and cause lasting damage. Asbestos was widely used in the UK before it was banned in 1999, so it is important to check any materials in older buildings.
