I know this is rehashing things... Dow claims: http://bit.ly/oQ1bNi
"Do THERMAX™ Polyisocyanurate Insulation or TUFF-R™ Polyisocyanurate Insulation outgas any toxic materials/gases? THERMAX™ Polyisocyanurate Insulation and TUFF-R™ Polyisocyanurate Insulation do not outgas any toxic material over their lifetimes. Foam insulation, like wood and other organic materials, can release toxic smoke if ignited." Ok. Still looking for info on the Owens Corning pink. But I did find this unrelated bit from aircraft builders: "On pink vs blue, blue floam from Dow was known (a long time ago) to not use any silicone in process. Silicone can seriously mess with the bond strength of epoxy, and so (a long time ago) the Rutan Aircraft Factory told us to only buy blue. Pink foam is Owens-Corning. It and others have an unknown silicone status. But then, the same thing may be said of Dow at this date...." They use silicone in the production process somewhere. This means there might be silicone residue on the outside of the panels. This is why tape won't stick to blue and pink boards.
