Is Mannington iCore Laminate Flooring or Vinyl?

Mannington iCore is not laminate flooring.  Or is it laminate flooring?   Which is it?

I was looking at this issue earlier today, in relation to an article about cheap laminate flooring.  I noticed that Mannington iCore advertised itself as being completely waterproof.

Huh?  I’ve never known a laminate flooring product to be completely waterproof.  Sure, there are ways to mitigate moisture problems with gluing the seams or simply installing in areas that don’t get huge amounts of water.  But waterproof?  The product description said that iCore was 100% a composite. Which does not describe laminate at all. Laminate is…laminated. It’s wood product-y stuff plus an image layer plus wear layer and glue and other stuff. But all composite?

So enough, the Mannington site fesses up to the issue and says.

iCORE®, although categorized as a laminate floor, is not the laminate floor you’d expect. iCORE® is an entirely new category of flooring…iCORE® is an Advanced Composite, an entirely synthetic product, which has a patent pending innercore construction. The entire product is waterproof.

Or, I guess they are fessing up, I’m not sure.  So, it’s a laminate but it’s not a laminate?  What gives, Mannington?
