Asbestos and vermiculite are common building materials in buildings, having been long used in such areas as insulation for pipes, boilers, ductwork, ceilings and walls, soundproofing, spray on insulation and rust-proofing, asphalt floor tiles, backing for vinyl sheet flooring, tile caulk, spackling and putty, exterior sidings and paints, to name a few. These materials can also been found in older vehicles, particularly the brake linings and clutch pads. Older heatproof gloves, fire blankets, and some paper and plastic products also have asbestos and vermiculite in their makeup.
Because of the widespread use of these materials in the home, it is best to have a professional assessment and removal work done to avoid unnecessary release of spores in the air that may cause great harm, such as lung cancer, to occupants.
