One of its key strengths is its natural soundproofing properties, which significantly enhance living comfort by reducing noise. This underlayment has also passed stringent acoustic tests, ensuring its effectiveness in sound control.

The green color and rectangular shape might not be to everyone's aesthetic preference, although these aspects are generally hidden once the flooring is installed. This underlayment is a robust and eco-friendly option that improves sound insulation, moisture control, and floor stability, though it may require some effort in handling due to its weight.
