Have found very little information on the inclusion or absence of ortho-phthalates in this line. Mannington does promote their floorscore certification, which they sent me, which is great, but they don't advertise anywhere that I've seen whether or not they use phthalates. Some brands make it apparent that they no longer use this, but some say nothing. I really like the look of this product, so far more than other samples I've received. My biggest concern with vinyl plank flooring is the safety regarding hazardous materials/gasses, so I've been trying to research different brands and whether or not they have floorscore certification and whether or not they use phthalates. I called Mannington, they sent me their floorscore certification and a document stating that they do not use phthalates. However, this is basically just a Word doc that someone typed up and made a pdf from. The grammar, punctuation, etc. is all odd, just doesn't seem very legit. Will try to upload what I was sent. Should I be concerned?
