The difference between homogeneous and heterogeneous flooring:

• Homogeneous the word itself means that it is basically one substance – it’s a single layer, top to bottom.
• Heterogeneous is simply a product that is layered, typically with separate chemistries for each layer of the product – and we will get into some examples of these.

The best way to tell a homogeneous product from a heterogeneous product is to flip the product over and look at the back vs. the front.

Essentially, if the product looks the same on both sides, it’s homogeneous. So, that would include traditional homogeneous sheet vinyl, rubber, VCT, solid vinyl tile, and cork – though you can have cork floor tiles with a layered, heterogeneous construction.
