Fiberglass is pink insulation and never included asbestos. However, the tar paper associated with batt insulation can contain asbestos. In addition, asbestos containing insulative materials were sometimes used in conjunction or were covered up with newer fiberglass insulation so care is needed in dealing with any old insulation. The only way to know for certain whether or not asbestos is present is to have the appropriate number of samples collected of associated suspect materials per your local regulatory guidelines often by a qualified person and them submitted to a NAVLAP certified lab for PLM analysis.
