fiberglass insulation and formaldehyde binders

Bill Sheehan from the Product Policy Institute in Georgia would like some further information on the use of formaldehyde binders in fiberglass bat insulation. The binder is used to bind the fiberglass fibers together. Johns Manville has switched to an acrylic binder, developed by Rohm and Haas. Other companies, including Certainteed in Bill's area, have stuck with formaldehyde binders. They reported trying a different formulation, using less formaldehyde, in order to reduce their formaldehyde plant emissions, but found that it increased their ammonia emissions.

Has anyone worked with Certainteed, Johns Manville, or other insulation companies on this issue? Any down side to the acrylic binder that you are aware of?
