This rubber cork roll is meant to be your ideal floor insulation which retains its insulation value for decades and offers long-time service. Practical floor insulation: The cork sheet is meant to be your ideal floor isolation for its high elasticity and long-lasting pressure stability. And its flexibility makes it easily pliable in curves and corners. Sound-dampened function: The floor underlay dampens sound and removes reverberation from the room. The thicker the cork wall, the more sound is blocked. Heat saving: The insulation underlay prevents unnecessary heat loss, and it brings a warm, comfortable feeling to any space. Convenient maintenance: Also, light dirt and dust on the cork sheet roll are removable with a slightly damp cloth or soft sponge.
