Urea formaldehyde foam insulation
, 1981 Urea formaldehyde foam insulation has been used in Canada for a number of years. Studies and reports subsequently identified instances of medical problems and structural deterioration of the buildings occurring after the installation of the foam. A ban on the use of urea formaldehyde foam insulation was announced by (National) Health and Welfare Canada
