• UREA-FORMALDEHYDE
  
  First used in building materials, particularly insulation, in the 1970s. Gases leak out of the urea-formaldehyde foam insulation (UFFI) as it hardens and become trapped in the interior of a building. Once used to conserve energy by sealing crawl spaces and attics, it is longer used because emissions were found to be a health hazard. (See formaldehyde)
