LoginRecent concerns have been expressed with regard to emissions of glass fibers from heating, ventilation, and air conditioning (HV AC) systems. In this literature review, over 350 citations were found, of which 10 reported original measurements of glass fiber concentrations associated with the presence of fibrous glass duct lining or duct board, and two yielded sufficient data from which emission rates could be calculated. This review indicates that fibrous glass duct lining and duct board can provide thermal and acoustical benefits while maintaining exposure to glass fibers in occupied spaces at or near background or outdoor air concentrations only if care is provided to maintain these materials in clean and dry conditions throughout the construction and operational phases of the facility.
