Most laminate floors can also be installed as floating floors. Manufacturers will often suggest a plastic filament or foam layer. And some products come with the underlayment already attached. Ask your local flooring experts about these options, and remember what we said about underlayment vs. Not sure if laminate flooring is for you?

Short answer—yes. But —these qualities all depend on proper installation. But what about the underlayment? Vinyl is similar to laminate flooring in that underlayment recommendations may vary. Again, ask your local flooring experts for accurate info and warranty requirements! And, unlike solid wood planks, tile can be installed in any room of the house. As with solid hardwood flooring, a thicker subfloor is necessary to support most types of tile.

As Bob Vila points out, the industry standard is a concrete backer board. A common tile installation method starts with a layer of thinset a mortar adhesive going over the subfloor.

Then, the backer board is put over the thinset and screwed into the wooden subfloor. You can install tile over concrete, vinyl, and even other tiles. They each have underlayment considerations that depend on the subfloor material and type of tile you are installing.

This method of laying a sturdy subfloor on top of joists and then topping the subfloor with a cosmetic-only flooring top creates a tighter, stronger structure. Layering makes it easier to change the visible floor if you tire of the look or if it has become damaged. Relying on the joists to shoulder the brunt of the load means that this floor top can be practically anything you like, as long as it performs a few basic duties like withstanding foot traffic. But one thing that this top, called the floor covering, does not have to do is to provide structural support.

Called a floor covering or finish floor, this might be ceramic tile , solid wood, laminate, engineered wood, luxury vinyl, carpeting, and many others.

Substrate is a general term that means any surface below another surface but which, in the home remodeling world, most often refers to the stabilizing layer of material directly beneath the finish floor. If you are installing solid hardwood or engineered wood, you may be putting down an underlayment of plywood. For wet, mortared applications, such as tile and stone, a cement backer board may be your first level below the flooring.

Laminate flooring gets a completely different type of underlayment: a thin foam that comes in rolls and which gets taped together.

Subfloor holds up all of the above layers of flooring, as well as everything in your house, including people, dogs, cats, pianos, furniture. All houses have subfloors. Joists are structural; they support everything above. Joists are made of engineered, laminated wood or dimensional lumber.
