The "laminate" flooring I used is made with ABS, a sort of plastic, that is commonly used for waste plumbing in houses because it is so durable and resistant to damage from common chemicals you'd have around a house. It is 100% waterproof - great for an RV.
It has a finish layer bonded to the ABS which looks like real wood but is some type of plastic.
There are two basic types of laminate used in a house. One is made from compressed sawdust and glue (typically much cheaper) and the other has laminated layers of thin wood just like normal plywood. The first one has a bonded layer on top for the finish, and the second type is usually (always?) real finished wood on the top layer.
Regular laminates in houses can be quite thick, around 5/8" which can pose problems in an RV. These laminates are not fully waterproof either, with some better than others. In addition, they can be easily damaged by high heeled shoes, dog's nails and dropping objects onto it.
We are so happy with it, we are thinking of using it in a rental suite in our house because a tenant can spill anything on to it and it will not be damaged.
