was installed by using pumpset and hoses with a mixing gun to mix the foaming agent and
the resin, to produce a "Shaving Cream" product called Urea Formaldehyde Foam
UFFI was installed under air pressure, up to 100lbs. of air pressure per square inch (psi)
and injected through 1/2" - 2" holes in mortar joints, drywall, wood siding,
aluminum siding, concrete blocks, etc.. Almost all forms of construction had UFFI
was also used as sound insulation, air sealant in commercial and industrial and has been
found in attics, common walls of row houses or semi-detached homes, office walls,
apartment buildings, condominiums and garage ceilings where rooms are over garages.
if the installation procedures which involved extreme air pressure, UFFI has been found in
many areas in which it was not suppposed to be:
sealant around columns and electrical outlets and switch plates
-windows and electrical boxes
-foundation blocks and sill plate
-attic and knee wall areas
-basement perimeter sill and floor joist plate duct work
-floor joists and ceilings between floors
-abutting wall attached walls where UFFI was installed
-between double brick
-between brick and cinder block
-between block or brick and gyproc and plaster
-in veranda overhangs
-in bay window boxes
-around noisy pipes in bathroom
-used as a sealing material (anywhere there was a cold draft UFFI could have been used)
course, UFFI is most extensively found in walls or residential homes in one of two ways.
It could be installed through the exterior sheathing, brick block, wood or aluminum
siding, shingles, insulbrick or cedar shakes - in some cases, prior to new siding being
installed or the shake or shingle removed, and then, reinstalled covering the holes with
wood and plastic plugs, mortar, etc.. Alternatively, it could be installed from the
interior by drilling holes through plaster and lather, gyproc or drywall - in most cases
holes were replastered or covered with wallpaper.
you have recently found or suspect UFFI and are looking for more information, contact any
one of the following: you local Canada Mortgage and Housing
Corporation Office; Consumer and Corporate Affairs Canada in Hull, Quebec, or the Canadian
Home Insulation Program in Montreal; the Ontario Ministry of Labour (did testing in 1981 and
1982 of houses); or your local municipal office. There are a number of laboratories that
do various UFFI testing and analysis in Ontario.
Formaldehyde Foam Insulation (UFFI) is as contraversial today as it was in December of
1980 when the first temporary ban was put into place. Discussing health concerns and
questions are beyond the scope of our expertise; however, we can advise you that there is
a great deal of disagreement over UFFI. For every person who disagrees with the ban on
UFFI, there is someone who agrees with it. This lack of agreement on UFFI covers a wide
spectrum of people and professions - scientists, doctors, chemists, home owners,
contractors and the legal profession.
the Province of Ontario most municipalities will reduce the housing portion of the
property taxes by 30% (excluding land and other structures) reflecting the reduced value
of the house by the same amount. In the Toronto area, houses with UFFI installed sell at a
reduced price, but after it has been removed, the house price reflects the general market
conditions in that area.
to the ban on UFFI, most Ontario real estate boards and financial institutions have
included in legal and financial documents clauses that the Vendor must identify whether
the property has, or has ever had UFFI. An example of such a clause is the
following: "The Vendor warrants this home does not or never contained Urea
Formaldehyde Foam Insulation (UFFI)."
