Laminate is called a floating floor because it is not fastened directly to the sub-floor, but rather the planks or squares are attached to each other. Because laminate is a floating floor, sub-floor preparation generally costs less than with other hard surfaces. In recent years we have seen the advent of glue-less laminate flooring, which has made the job of laying laminate flooring far easier and quicker than ever before. Glue-less laminates do not require glue, but rather have a trademarked locking system that hooks, snaps or clicks the tongue and groove together to lock the floor into place.
