Asbestos siding is a type of siding that was used between the 1920's and 1970's. There are health concerns with the use of asbestos on homes now. Asbestos was then added to cement to provide support, fire-retardant properties, and insulating. You can compare asbestos siding to others on the internet or go to a home-improvement stores.
Many older homes are still in use with asbestos siding. As long as the asbestos is not damaged and is sealed off, there is little danger at the moment. If the asbestos is damaged or frayed, the home is possibly dangerous and the siding should be removed. To prevent asbestos from becoming a threat, cover it with vinyl or have it painted over with a thick layer of vinyl paint.
The only way to know for certain if cement siding contains asbestos is to have a small sample tested by a qualified laboratory.
If the siding was manufactured in the 1970s or earlier, it may contain asbestos. To know for sure, the siding must be examined under a microscope by a specialist. The material should be relatively safe if the fibers are contained within some sort of plastic or epoxy and is not disturbed. If the fibers are exposed and frayed it is a safety hazard and should be removed by qualified individuals using proper safety equipment and procedures. When the material is disturbed, the asbestos fibers will become airborne. If the siding was manufactured in the 1980's or later, in the US, Western Europe or other countries, it will not contain asbestos. However, siding in some parts of the developing world may still contain asbestos.
Before it was banned in the late 1970's, asbestos siding was installed on several hundred thousand houses within the United States. The asbestos is not a harmful health risk unless the siding is cracked, damaged or deteriorating. Inspect the siding regularly and replace any damaged tiles with non-asbestos versions. Should the siding have to be removed, it should be done by a professional who will follow all applicable ordinances regarding the handling and disposal of asbestos containing products. This is necessary because the dust created during removal may be laced with asbestos which can enter the lungs and cause mesothelioma.
I certainly hope not!
