Would click and lock engineered wood flooring be glued down to a concrete slab floor to enhance soundproofing?
Click and lock engineered wood floors are designed for installation over a moisture proof soundproofing sheet membrane. The membrane absorbs much of the hollow sound and acts as a sound barrier. Its effectiveness depends on the product so each manufacturer’s specifications should be studied before making a decision. An important feature which enhances the soundproofing effect is the flatness of the concrete floor.
Choose a reputed manufacturer of engineered wood and use a recommended adhesive. Provided all these aspects are taken care of, lock engineered wood is a good choice.
