Asbestos Siding
Asbestos siding (also called asbestos cement siding) has been commonly used in homes since 1920s and can still be found in many older buildings. It was made by adding asbestos, a natural fibrous mineral, to Portland cement, then pressing into siding shingles of various textures, profiles and sizes. Asbestos is known to possess fire-retardant properties and add durability/strength/insulation to the siding. Asbestos is also considered to be relatively cheap to manufacture/maintain/upkeep, resistant to the elements, easy to paint and clean.
Unfortunately, it took decades to confirm a lurking problem with asbestos, as its fibers could cause health problems if they were inhaled or became airborne. Although, it has been still present in many homes because asbestos siding on one’s home poses no health risk as long as it is undisturbed.
In the past, asbestos fibers were added during siding production to provide a limited amount of insulation, strengthen materials, to increase their durability and home fireproofing.
