Steve,
I have not heard any reports of problems associated with off-gassing from XPS. By the time it reaches the job site, the foam is fully cured.

Remember, there is no reason for any XPS to be exposed in a home (with the possible exception of rim-joist areas). Ideally, all of the XPS in your home will be covered with gypsum wallboard, concrete, or some similar air barrier.

GreenGuard certifies only the Corning Foamular XPS as meeting its indoor air quality standards - FOAMULAR® insulation is also the only extruded
polystyrene product certifi ed by the GREENGUARD
Environmental Institute’s GREENGUARD Children
and Schools Product Certifi cation under the
GREENGUARD Standard for Low Emitting Products.4
GREENGUARD certifi cation means that certifi ed
Owens Corning products contribute to indoor
air quality. - but does not certify any Dow products. Does anybody know the reason?
