What is no added urea formaldehyde (NAUF)?
A term used in the construction industry to describe materials that have no added urea-formaldehyde in the manufacturing process. The term refers specifically to the binders used in composite panel production. Alternative adhesive systems that qualify for the NAUF category would include: Phenol Formaldehyde (PF), Poly vinyl acetate (PVA) and Soy. LEED (Leadership in Energy and Environmental Design) has also adopted the no added urea-formaldehyde terminology under the credit EQ 4.4. The popularity of LEED has driven this term into the mainstream as the public becomes more concerned with issues of indoor air quality.
