Urea Formaldehyde Foam Insulation (UFFI)

Urea Formaldehyde Foam Insulation (UFFI) was and still is used as a retrofitted insulating material in walls and ceiling spaces. It was used during the late 1970s "energy crisis" to retroactively insulate balloon frame construction houses and other buildings to increase energy efficiency. In Canada, approximately 100,000 to 280,000 homes were insulated with UFFI, in many cases subsidized through the Canadian government's C.H.I.P. program. UFFI was also used commercial and industrial buildings. It can be found in common areas and walls of semi-detached homes, offices, apartment buildings, condominiums and other habitable spaces.

It was discovered in the late 1970s and early 1980s that this foam outgassed potentially toxic formaldehyde fumes which were linked to serious respiratory illness. UFFI when first installed had the potential to release significant amounts of formaldehyde into indoor air which resulted in acute adverse health effects such as eye, nose, and throat irritation, headache, and nausea. However,
formaldehyde levels in UFFI houses dropped rapidly after installation and health complaints usually subsided with

Use of UFFI as an insulator has been banned in Canada since the early 1980s. UFFI was banned in the United States in 1982 by the Consumer Product Safety Commission. This ban was overturned by the U.S. Court of Appeals a year later. Some US states still have a state ban. UFFI was never banned in Europe, where it was originally developed and has been in use since the 1950s.




UFFI Survey: A detailed inspection of the home, sampling material suspected to be UFFI. 


UFFI air sampling -

Air testing for the presence of Formaldehyde is generally mandated based upon two typical scenarios: the suspected presence of Volatile Organic Compounds or the presence of UFFI (Urea Formaldehyde Foam Insulation).


The number of samples collected is dependent upon the size and layout of the suspect property and is the main factor determining cost. Typically, formaldehyde testing is prompted by due diligence requirements related to a real estate transaction and often sampling may require as few as one sample per affected area or floor.


The collection and submission of air samples to a third-party laboratory of air samples to determine the concentration of formaldehyde in the home.
