urea-formaldehyde insulation foam (UFFI)
Urea-formaldehyde insulation foam (UFFI)
Urea formaldehyde foam insulation (UFFI) was widely used in the 1970s as an insulation material in Canadian homes. However, it was banned in December 1980 due to its potentially irritating and toxic effects.
Although UFFI has not been used for over 40 years, concerns remain about its residual effects in homes where it was once installed. According to Health Canada and the Canada Mortgage and Housing Corporation (CMHC), UFFI should no longer be releasing toxic gases today. However, if UFFI is exposed to water or moisture, it may degrade and re-release formaldehyde. In this case, it must be removed by a specialized contractor to eliminate the source of the moisture problem.
History
Urea formaldehyde foam insulation is a foam-injected insulation used to insulate buildings. This insulation method was very popular in the 1970s, due to the high cost of oil-fired heating following the oil crisis. The federal government subsidized this type of insulation for a time.
Effects of formaldehyde
-
Formaldehyde is an irritant that can cause burning sensations in the eyes, nose and throat.
-
It can also be linked to respiratory problems, particularly in asthmatic children.
Cancer risk
-
Although formaldehyde is recognized as a carcinogen, the concentrations normally found in homes are highly unlikely to cause cancer.
