In addition, these asbestos cement roof sheets
provide good thermal properties and adequate fire durability,
strength and flexibility. However, this type of roof sheet also
contains toxic substances that enter the body through the respiratory
system and can cause conditions such as Asbestosis, chronic
lung disease, malignant pleural disease, tumors, and cancer of
the lung and other parts of the body. Alternatively, there are
other types of roof sheet which are safer to human health, such
as concrete roof sheets, ceramic roof tiles and fiber cement roof
sheets with a range of prices and physical properties.
