This is true in the case of engineered wood flooring and laminate flooring is usually considered a form of engineered flooring – though actually there is a subtle difference.
Essentially engineered flooring is created by using two or more layers of wooden planks. These woods are then different from each other and while the top layer will be visible, the second layer is the core or substrate and is not visible. The core then is designed in order to provide the stability for the floor and the firmness and weight, while the top layer is designed to provide the attractive look of the floor.
This is different technically from laminate flooring for the simple reason that laminate, vinyl and veneer use different types of layer and substrate. For instance with laminate flooring it is actually an image of the wood that is used on the surface. Meanwhile with vinyl, it is a plastic that is designed in order to look a lot like wood.
