There are particleboard products that are NAF with third party certifications that LEED reviewers will not accept because they do not have a CARB exempt executive order. I have asked reviewers to clarify why this is and only received a reiteration of the requirement. In other categories, there are a variety of emissions testing certifications that will comply. Can anyone explain why a composite product that is made with no formaldehyde and certified as such by a third party that is accepted in other categories would not be acceptable in this one?
