FAQs about IEQc4.4 :

Our project is planning to use no composite wood products. Do we automatically earn this credit?

We have a product that complies with very stringent E1 and E0 European standards for low emissions. Does this product comply with this credit?

I've been told there's no marine grade plywood product that I can use on foodservice millwork that complies with this credit. Is this true? If so, is there a NAUF equivalent or similar product that people are using for millwork that is good for food service areas?

Doesn't sound right to me. Since UF is vulnerable to moisture I would have thought that marine-grade plywood would be using PF, MDF, or MDI, etc.

Tristan is correct. Composite woods intended moisture-exposed applications would not use UF, Wikipedia has a web page for plywood, and the following is stated there. "Plywood for indoor use generally uses the less expensive urea-formaldehyde glue, which has limited water resistance, while outdoor and marine-grade plywood are designed to withstand rot, and use a water resistant phenol-formaldehyde glue to prevent delamination and to retain strength in high humidity." http://en.wikipedia.org/wiki/Plywood Wiki also has a short primer on marine grade plywood on the above link.
