What does UFFI stand for in real estate terms?

UFFI stands for Urea-formaldehyde Foam Insulation. This term refers to a type of insulation that was commonly used in the 1970s and 1980s due to its effectiveness as a thermal insulator. It is made by mixing urea-formaldehyde resin with a foaming agent, creating a lightweight insulation material that could be sprayed into walls and cavities. Over time, UFFI lost popularity because of concerns regarding indoor air quality and potential health risks associated with the release of formaldehyde gas from the insulation material.

The other choices do not accurately represent the established term in real estate. For instance, Uniform Federal Foam Insulation and Urban Foam Finishing Industry are not recognized terms, and Unfinished Foam Formulation Insulation does not describe a specific type of insulation product widely known in real estate contexts.
