CS-2009 IEQc4.4:Low-Emitting Materials—Composite Wood and Agrifiber Products

Are Phenolic Formaldehyde resins OK?

Hello - I am working on a project where the subcontractor has requested we approved a product that uses a WBP Phenolic Formaldehyde binder. I have seen this statement published in 2 different places, but not on a LEED-sanctioned page: "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." Does this mean that PF resins automatically qualify for IEQc4.4 as an alternative to NAUF, or is the above statement intentionally misleading?
