None were linked to UFFI. Lawyer’s Weekly (July 7, 1989). Urea-formaldehyde foam (UFF) insulation. No one knew exactly how many homes had UFFI, and it was often difficult to find out whether a home had UFFI. UFFI or Urea Formaldehyde Foam Insulation was an insulation retrofit product used in the 1970's. As testing methods improved, the level was brought down to 0.5 ppm and, eventually, 0.1 ppm. UFFI was a type of insulation that was widely used around the World, including Canada, USA, and Europe.

Urea-formaldehyde foam insulation (UFFI) was developed in Europe in the 1950s as an improved means of insulating difficult-to-reach cavities in house walls. The problem was further complicated by the fact that the foam was often used somewhat inappropriately in walls of solid masonry houses, in attics, in cavities where freeze-up of pipes had occurred, and even as an acoustical insulation in party walls in row houses, and in the ceilings between the first and second floor of the house. If you suspect your indoor air quality to be poor, there are Environmental Consultants listed in the Yellow Pages of your phone book, often in the Business and Industrial section.
