Although a subfloor is not always necessary, it offers many advantages. They are noticeable as soon as you start installing the floor because, after all, a subfloor will neutralise or partly neutralise any unevenness. The installation itself will also be a lot quicker. However, the main advantage is that a subfloor will reduce walking noise. The difference is clearly audible. Some collections already have integrated subfloors. This means that don’t need a separate subfloor - in fact, you must not use one.
