Cork underlayment is environment friendly material. The underlayment is produced from bark of cork oak. The bark is chopped and pressed under pressure. Chemicals aren’t used in the production. Due to suberin, the cork pieces stick together spontaneously. Suberin is mucilage which is contained in the oak bark. That’s why cork underlayment has exclusive benefit as it doesn’t emit toxic substances.

  • Shock absorbing capacity:     10%
  • Tensile strength:     2 kg/m2
  • Noise reduction coefficient:     0,85
