Flooring underlay, also known as underlayment, is a barrier that goes between the flooring and the sub-floor. Made of a high-density polyethylene, a quality underlay acts as both a vapor and sound barrier. Flooring underlay also smoothes out imperfections in the sub-floor, helping to level out the surface before you install your floor. Many apartment buildings and condos insist on a quality flooring underlay before granting permission to install wood, engineered wood or laminate floors. This is because a quality underlay will reduce impact sounds from walking on your floor.

Not only does flooring underlay diminish floor-to-ceiling noise but it also dampens ambient sound in the room in which it’s installed. It also stops moisture from penetrating into your wood, engineered wood or laminate floors from the concrete sub-floor below. Flooring underlay is easy to install and complete directions on how to install it are included on our website.
