Since the early 1980s, urea-formaldehyde foam (UFFI) insulation has been banned in Canada due to its negative impacts on health. There are still many houses whose walls contain MIUF. In fact, it is estimated that nearly 80,000 homes in Canada have been isolated with MIUF.

MIUF insulation, under its full name urea-formaldehyde insulating foam, is an insulation product that was used for the insulation of buildings by injection under pressure. Initially banned in December 1980 under the Hazardous Products Act (LPD), it was during its installation that it was first revealed to be the most toxic, while a high density of formaldehyde was released, but also subsequently the escape of contaminating gas if the product has been incorrectly installed.

But why the MIUF?

On this subject one could not rewrite more accurately than Wikipedia does:
“The initial appeal of the MIUF lies in its low cost, its high insulation capacity, and its ease of use, especially in the case of existing homes; all you need to do is drill holes along the exterior wall and inject the foam into them, a much simpler procedure than opening a wall required when adding insulation in mats or rolls. Unlike loose insulation (like fiberglass and mineral wool), foam spreads more evenly and does not sag over time.

At the end of the 1970s, more than a hundred thousand people chose to isolate their residence at the MIUF. In Canada, as early as 1977, the government offered a grant of $ 500 to homeowners who adopted this insulation as part of its program for thermal insulation of Canadian residences . “(Source Wikipedia ).

An installation before the 1980s poses little impact with regard to the concentration of formaldehyde in the ambient air inside the building. However, it is noted that the UFFI which is in contact with humidity and water, causing its degradation, will then cause a higher release of formaldehyde. Two challenges therefore await occupants or owners:

Miuf: locate the source of moisture and water infiltration

Here the role of the building inspector is crucial. First, because he will be able to detect any sources of water infiltration or the presence of humidity, as well as inform you adequately about the presence or not of UFFI. It is also he who will be able to offer you a range of recommendations as to solutions for decontamination of MIUF and its removal.

Miuf: Decontamination - removal by an expert

Again, we cannot recommend enough caution with regard to the means to eliminate UFFI . The insulating foam urea-formaldehyde should be grasped with care and caution. Following the building inspection, your professional will be able to recommend appropriate means and solutions to protect your investment.
While the presence of MIUF isn’t necessarily a problem, it can still cause a potential buyer to worry and, in turn, lower the value of your property. In some cases, it will cost several thousand dollars to remove it. *

Struggling with MIUF? Choose to do an inventory

Too often people only hire a home inspector when they are transacting or putting their property up for sale. They then find themselves in an emergency situation or under pressure to manage a problem that it would often be much better to be able to foresee and manage when you are most able to do so. So is the protection of your investment.

It may therefore be useful and wise to have your home inspected to assess the problem and be able to establish, based on the report that will be provided to you, how you wish to apply the recommendations offered by your certified inspection professional.

To learn more about MIUF insulation

In the wake of the owners who learned about the health risks associated with this insulator, the Société Radio-Canada produced an important file on the subject. You can consult it in the archives of the Crown Corporation.
