Asbestos cement sheets are construction materials typically used in roofing and siding. Asbestos fibers were mixed into cement to improve weather resistance and corrosion. Today, asbestos cement sheets may still be present in some homes and buildings. As a result, individuals may risk exposure.
What is the function of asbestos sheet?
Also known as cement wallboard and asbestos millboard, asbestos cement boards were produced in sheets. They were used as a fireproofing material around boilers, heaters and wood stoves. Asbestos board was also used for automobile hood liners and as gaskets and washers in electrical applications.
What is asbestos and what are its advantages?
Asbestos is a very good thermal insulator and increases the energy efficiency of the building. It is highly resistant to fire and does not burn easily. It forms a very strong material when mixed with cement and used as an additive to form a composite material called asbestos cement.
Is asbestos banned in India?

How do I know if my sheets are asbestos?
Asbestos cement sheeting or fibro will produce a sharp or clicking sound when tapped by a car key indicating a very hard and brittle, high-density product. Using hand pressure, the head of a screwdriver will not penetrate the surface and will usually just scratch paint off.
What is asbestos still used in today?
Asbestos has also been used in a wide range of manufactured goods, mostly in building materials (roofing shingles, ceiling and floor tiles, paper products, and asbestos cement products), friction products (automobile clutch, brake, and transmission parts), heat-resistant fabrics, packaging, gaskets, and coatings.
Where is asbestos commonly found?
Asbestos is also present in the environment naturally, primarily in underground rock. In most areas asbestos fibers are not released into the air because the rock is too deep to be disturbed easily.
What happens if you breathe in asbestos once?
It is possible to develop an illness such as asbestosis, mesothelioma, pleural effusions or lung cancer after a one-time exposure to asbestos if the exposure was significant enough to lead to asbestos particles lodging in the body’s tissues. The 9/11 attack is a common example.
How do I know if asbestos is in my home?
A visual inspection of your home is usually not sufficient to determine if it contains Asbestos. The build date of your home is a good indication, but the only way to truly know is to send a sample of the suspected fibers or material to a certified laboratory for analysis.
