How is this different than the COREtec Plus 7"? I see that this is 5mm thick, and the COREtec Plus is 8mm, but is that the only difference? What difference would the thinner or thicker plank provide?
The two products have different core construction. The Pro Plus product is a rigid core SPC product, which means that it is denser while also being thinner. Pro Plus is approved for high traffic commercial spaces. The regular Plus products are wood polymer / waterproof core, and have a foaming agent which makes the planks thicker. Coretec Plus products are more suited for use in the home and light traffic commercial spaces.
