Marvin Fiberglass Windows

I purchased several Marvin Fiberglass windows and had them installed two and one-half weeks ago. Right after installation we smelled a strong acrylic odor throughout the house, which has only abated a little bit.  After two weeks of research I discovered that the fiberglass is actually coated with something called "acrylic capstock". I have searched everywhere and cannot find out how harmful this odor is and when it will stop outgassing.
