"Sound Design" - the silent step guarantee. Except for Basic Clic and Smart Clic, all the above laminate floorings are available with a fifth layer, "Sound Design" (footfall sound reduction). "Sound Design" makes a sensible choice into a sensual pleasure. It reduces the footstep impact, decreases noise generation and increases walking comfort. And it levels out small irregularities in the subfloor's surface. A floor can hardly offer more comfort or well-being.
