Does anyone have experience or know whether GBCI accepts MDF with melamine-urea-formaldehyde (MUF) in it for IEQc4.4? The melamine is a scavenger additive that serves to reduce the rate of formaldehyde emissions. I assume the improved hydrolytic stability that the melamine brings to the MDF meets the intent of the credit, since even pure solid wood has formaldehyde emissions making getting to zero literally impossible. Since no specific limit is set in the LEED Requirement, nor is there a related LEED Interpretation or CIR, I am left wondering... MUF is NOT UF and the manufacturers would gladly write a corresponding letter, but does the obvious need to be stated simply because there is a "U" in MUF? As far as I can tell the Healthy Building Network provides a list of composite woods with no added urea-formaldehyde (http://www.healthybuilding.net/healthcare/2008-05_ProductComp_NoAddUrea_...) and they list melamine formaldehyde as the binder, which as far as I understand can not be used as a wood binder without the urea, so I am left wondering, does MUF count as no added urea-formaldehyde?
