Underyoo Wisperwalk underlayment provides a firmer foundation, a quieter step and a higher insulation value than the basic underlayment. It's an excellent choice for those with more active households, rooms with high ceilings that tend to echo, or just homes where sound seems to easily travel from one end to the other. And because it's slightly heavier than basic foam, it lays more easily. Your new floor will likely be there for decades, so the extra cost is well worth it.
