i would buy a house with that insulation in a NY minute. it has all dried by now and no formaldehide fumes would be present anymore.
Jo,
That is not eactly true. Products with Urea Formaldehyde Foam Insulation was banned by the Consumer Product safety Commission in the 1970's. However, a federal court overturned that decision stating that the CPSC did not have the authority to do so. It is on the market now. It is now most often used as a sealer in hard to reach places. it also usually now has a bright color to it. I have seen both red and orange. It come in pressurized cans with a long straw attached to reach hard to get to places.
The original UFFI can became a problem all over again, many years after it has dried. This can happen when it is affected by moisture due to either high humidity, rain, leaks, etc. It gets revitalized and again gives off a gas that can affect some people with allergies and resperitory problems. Any real evidence or indication of a home insulated with UFFI should be noted by the appraiser. Since I am not an expert in environmental hazards, i usually state it this way:
"The appraiser is not an expert in environmental hazards or conditions. the appraisers report should not be considered an environmental assessment. The appraiser, based on the age of the subject, and/or observation, cannot rule out the possibility of_________________________. (Lead baaed paint, Radon, Asbetsos, UFFI, PCB's etc.) Any such concerns should be addressed by an environmental professional".
