Did Villaboard used in the early 1970s have asbestos?

Yes, Villaboard, a type of fibrous cement board used in construction, commonly contained asbestos in its formulation during the early 1970s. Asbestos was widely used in building materials for its fire-resistant properties until its health risks became more widely recognized. Consequently, many older buildings using Villaboard may still pose asbestos exposure risks if the material is disturbed or damaged.
