What is asbestos?

Asbestos is a set of naturally occurring silicate minerals used commercially for their physical properties. It became popular among manufacturers and builders because of its resistance to fire, heat and chemical damage, average tensile strength and sound absorption. It was used for electrical and building insulation. Roofing products were manufactured with asbestos from the 1920’s to the 1980’s. Asbestos-containing materials can be found in nearly 80% of structures built prior to 1981.

However, asbestos was discovered as a very harmful substance. Asbestos contains microscopic fibers which float freely through the air when disturbed and are easily inhaled. Asbestos can cause a cancer known as mesothelioma. For years, many workers who inhaled asbestos were not aware of the hazards. Always consult a professional prior to beginning any construction project on all pre 1981 structures.
