Anthony,
Are Wood I joists banned in NFPA? Is this something that NFPA is trying to do right now? It sounds like the problems are with the OSB. Is that correct? If OSB is that much of a problem are there any issues with using OSB for roofing and flooring rather than regular plywood? I would think roofs made with OSB might go up in flames faster and make it even more dangerous....yet another reason in my mind to use real plywood as a roofing material. Is it just the I joists which have the OSB web which are a problem? I know they also make I joists with tubing as the webs or 2x material for the webs. Should OSB be banned altogether?
