AbstractThe urgent need to conserve energy in buildings has increased the use of non-conventional insulating materials such as urea formaldehyde foam insulation (UFFI) in Canadian buildings. Although UFFI is not a particularly good insulating material because of its high initial water content and therefore its high volumetric shrinkage and known deterioration with age, it was installed in more than 80 000 Canadian homes before December 1980 when its use was banned under the Hazardous Products Act. The ban was based on an investigation by an Expert Advisory Committee set up by the Department of Health and Welfare Canada. Subsequent studies in the laboratory and in the field have indicated that gases and/or particulates given off by UFFI cause illness in some people. The nature of the problem and some of the studies carried out in Canada to improve understanding and develop methods of reducing exposure to the substances given off by UFFI are described.
