Thermal insulation materials for chimney pipes are concerned to deteriorate by freezing and thawing effect especially in cold areas. In this research, airborne fibrous particles concentration was measured at indoor, inside of chimney pipes and outdoor around buildings which use asbestos containing thermal insulation materials for chimney pipes, and degree of deterioration of those materials was verified. As a result, asbestos fibers were detected indoors of 2 buildings, inside of chimney pipes of 5 buildings and various degree ofdeterioration of thermal insulation materials for chimney pipes were examined.
