I think your descriptions are going to confuse people. You speak about "wood laminate on top" of a vinyl....do you mean "wood look" appearance????

And I'm not sure what "wood with laminate on top and/or MDF with laminate on top"? Are you talking about 2 different things?????

A laminate floor is a photograph sitting on top of a core (often HDF or MDF). There are "engineered wood floors" that are on top of HDF core (a "real" top layer of actual hardwood species glued to an HDF core so that floor clicks together).

I'm getting confused with your wording - sorry to say.

What type of "humidity" are you talking about? What area in the world are you looking at? What type of heating/cooling system are you working with? If wood isn't an option with humidity, then anything with an HDF/MDF core is going to be WORSE....so I'm a little confused.

Please clarify with WHERE you are and what you mean by the multiple descriptions of multiple types of floors (you have above).

PVC will last 200 years or more! This is the stuff used in drain pipes.

Please describe the exact conditions where you will be installing - at or above grade or below grade, local climate, ambient temperature and humidity, kitchen, bathroom or other room, etc.

Also indicate which products you're considering using generally accepted terminology.

Last thought: Not all flooring is alike, and the question is not just whether PVC vs. vinyl vs. wood vs. ??? is used. One must also consider the exact stackup, lamination, coating, structure, adhesives etc. of all these products to know the flooring's ultimate performance.

Hi, I apologize. English is not my native language; neither am I very familiar with terms that would be used by those who work at professional home remodeling. I'll try to clarify or explain the best I can.

First, this project I'm foing is for kitchen *cabinet* remodeling, not flooring. I apologize if I was not more clear regarding this.

Second the available materials for the cabinets they have are: solid wood, mdf and PVC board. What I mean by "laminated", is veneer sheets. Here, it is very common for cabinets to be laminated with glued veneer sheets that look like wood, either for appearance or to protect the surface(even wood ones); some people use some sort of vinyl sticker that looks like wood(similar to ikea furniture).

By "humidity" I mean water from the sink, as well as dishes air drying, the steam coming from the dishwasher, spills, and any other forms of humidity found in a kitchen.

By heat I mean a over the counter cook top, an over the counter oven and a dishwasher.

This place has tropical weather with high humidity. Similar to florida in the summer and maybe like 90degrees farenheit.

The kitchen measures about 8' x 10', with one window(although I think neither of those are relevant).

I am not really sure about the answer to your question.

You can laminate wood onto anything really, lamination has several purposes (1) to stabilize hygroscopic wood expansion, (2) to lower costs and (3) to increase the board footage of particularly appealing wood pieces.

When we talk about durability and quality of laminated products we are really talking about 1 and 2. Wood is hygroscopic so it expands and contracts with changes in humidity. Specifically the grain will swell, but they will not lengthen. So wood boards get wider but not longer. Laminates such as plywood stabilize the wood by making mechanically bonding boards to other boards facing different directions, as the grains attempt to swell in width the mechanical bond to other layers facing different inhibit the swelling.

So what gives laminates stability is actually the mechanical bond of glue. So when talking about the quality of various laminates, the glue rather than the material is more important. I have had plywood start delaminating before it was even cut.

I have no specific knowledge of this product but one of the advantages of wood on wood bonds (or any wood based materials) is how well they accept adhesion. I am not so sure you can achieve a great mechanical bond between wood and pvc. Now if they could do some kind of hydrosonic weld between pvc and wood it would work well, but pvc is much more difficult to glue than wood.

Having said all of this, it really doesn't matter. The cabinets that I just replaced were solid wood and built in 1908. They were in perfect shape but really a kitchen built in 1908 no longer met our needs. Solid wood will last much longer than your lifetime when properly cared for, the same goes for quality laminates. I am not sure how much more round we can make that wheel. In the end, finding a material that will last two lifetimes is probably not worth the effort.

Note: most of the pvc products are not laminates, they are solid pvc that are painted to look like wood. Not really a fan of those but whatever floats your boat.
