Is cement board a suitable soundproofing material?
Due to the low density of gypsum board, it provides superior sound insulation than other types of building materials. But there are other options, like cement board, which provides excellent sound insulation. For example, foam cement, which has a lower density than plaster but provides superior sound insulation, is another option.
Is it true that cement board contains asbestos?
asbestos cement contains asbestos fibres because the fibres are present inside the cement itself; as a result, the asbestos cement will have a cement-rich surface, which keeps the fibres contained. However, if the cement is subjected to any abrasive cleaning or working, considerable – and potentially deadly – volumes of fibres may be released into the environment.
