What is UFFI?
Urea formaldehyde foam insulation (UFFI), which is pronounced “you-fee,” is a foamed-in-place insulation used to insulate buildings. UFFI insulation was very popular in the 1970s due to the high cost of oil heating following the oil crisis. The federal government subsidized this type of insulation for a time.
While effective at insulation, UFFI can release formaldehyde gas, potentially causing health issues and negatively impacting property values.

Whis is UFFI a Concern?
The use of urea-formaldehyde foam insulation began in the 1970s and was banned in the early 1980s due to its potential as an irritant and toxin. As UFFI has not been used since the 1980s, there should no longer be any toxic outgassing according to Health Canada and the Canada Mortgage and Housing Corporation (CMHC).
However, UFFI could deteriorate if it comes into contact with water or moisture. UFFI that is wet or disintegrating (e.g., because it is in poor condition or work is being performed) must be removed by a specialist and the source of the humidity eliminated, as the case may be.
Common Signs of UFFI in Older Homes
UFFI insulation may be present if your home or building was constructed between 1970 and 1980.
Indicators include:
-
Presence of brittle or powdery foam
-
Musty or chemical odors
-
Insulation deterioration


Health Risks Associated with UFFI Exposure
Exposure to formaldehyde from UFFI insulation can cause:
-
Respiratory issues
-
Eye, nose, and throat irritation
-
Allergic reactions
-
Increased risk of asthma attacks (specially in asthmatic children)
Although formaldehyde is a recognized carcinogen, the concentrations normally found in homes are very unlikely to cause cancer.

Our UFFI Testing Process: Fast and Reliable
STEP 1
Inspection and Air Quality Testing
UFFI air quality testing consists of a visual inspection performed by our professional technicians, to look for visible signs of UFFI insulation, assess air quality, and detect any signs of formaldehyde.
Additionally, air quality tests are conducted on each relevant floor to measure formaldehyde concentrations, comparing them against safe baseline levels recommended by Health Canada (set short-term exposure at 0.1 ppm (parts per million) and 0.04 ppm for long-term exposure).
STEP 2
UFFI Materials Testing and Laboratory Analysis
To conclude that the material is UFFI, the analysis will determine the presence of formaldehyde, and will check the appearance and physical properties of this sample.
Samples collected during the inspection are analyzed in a certified laboratory. A comprehensive report detailing the laboratory findings, potential health risks, and clear recommendations for removal or management of UFFI insulation is provided.
Certified Experts in UFFI Detection
Multitest provides clear, detailed reports, enabling you to make informed decisions about property safety and potential remediation steps.
Our highly-trained and certified experts specialize in accurate detection and testing for UFFI, delivering reliable and actionable results.
Test quality and Credibility for UFFI
