Does this vinyl flooring or the polyethelene vapor barrier emit VOC's?

Hello Steve - thank you for your inquiry. As far as the Style Selections Flax rigid core vinyl planks, we could only speak on those. Novalis products undergo strict indoor air quality testing. Volatile organic compounds, or VOCs, are potentially harmful chemicals that can be emitted by furniture and furnishings. Novalis products meet some of the world’s strictest VOC emission limits, earning FloorScore, Indoor Advantage Gold, and GREENGUARD Gold certifications. As far as the polyethylene vapor barrier, you would have to contact that product manufacturer. Hope this helps answer your questions. Thank You -
