2. Sound insulation -- rubber and cork outperforms other materials in sound insulation;

3. Shock absorption -- the underlayment is soft and durable to cushion the floor so as to protect children and elders specially;

4. Thermal insulation -- the thermal conductivity is 0.12W/mk which reaches to the standard of thermal insulation;

5. Fire retardant -- the rating is B2 DIN 4102-1;

6. Mould resistance -- it resists the growth of mould, bacterial, fungus;

7. Easy installation -- to lay the product on the subfloor easily and it will not roll up or deform, DIY is workable for saving labour cost.
