Laminate flooring requires an underlayment. You get what you pay for when it comes to flooring underlayment. Cheap is not always better. There are several types and price ranges available, and each manufacturer of flooring has a recommendation for the type of underlayment that should be used.he purpose of underlayment is to reduce sound, provide a moisture barrier, aid with subfloor imperfections and slightly cushion the feel of your floor as you walk on it. All of these things must be considered when you purchase your underlayment.
Some laminate flooring, such as Pergo Accolade and DuPont RealTouch, have the underlayment already attached to the bottom of the floor. So, not only is it unnecessary to add extra laminate underlay, it is not advised. Otherwise, you will end up with a floor that is too squishy and does not wear well.inally, sub-floor imperfections may telegraph to the surface of your laminate.
