Natural Cork: Returning to the Essence of Comfort and Protection
Key Highlights
Cork, as a natural gift from the Mediterranean cork oak, retains its most original ecological properties. The 2mm-thick cork layer is formed by gently pressing natural cork granules, and its unique honeycomb structure acts like countless microscopic springs, naturally dispersing pressure and absorbing impacts to provide cushioning protection for flooring. This natural material offers excellent elasticity without the need for chemical additives and maintains its breathable characteristics, creating a "breathable" protective layer when in contact with the floor, avoiding potential moisture retention issues that can arise from complete sealing.
Frequently Asked Questions
What is the CORK 20-P underlayment made of?
The CORK 20-P underlayment is made entirely of natural cork — a renewable material harvested from the bark of Mediterranean cork oak trees. It is formed by gently pressing natural cork granules together, with no chemical additives required, preserving its original ecological properties.
Is the CORK 20-P underlayment compatible with underfloor heating systems?
Yes. The CORK 20-P is specifically designed for use with underfloor heating systems. Its low thermal insulation value of 0.05 w/mk ensures efficient heat transfer while still providing adequate cushioning and protection for laminate, hardwood, bamboo, and vinyl flooring.
What are the sound insulation ratings of the CORK 20-P?
The CORK 20-P achieves an IIC (Impact Insulation Class) rating of 50db and an STC (Sound Transmission Class) rating of 46db. These ratings demonstrate its effective performance in reducing both impact noise and airborne sound transmission between floors.
How does the cork underlayment handle moisture?
The CORK 20-P has an exceptionally low water absorption rate of less than 0.1%, making it highly resistant to moisture. Additionally, its natural breathable structure creates a "breathable" protective layer between the subfloor and the flooring, helping to prevent moisture retention issues that can occur with fully sealed underlays.
What packaging options and load quantities are available?
The CORK 20-P is available in Nude, Pallet, or Carton packaging, offered in roll sizes of 100 sq.ft or 200 sq.ft. For bulk orders, a standard 20GP container holds approximately 12,000 sqm (129,000 sq.ft), while a 40HC container accommodates up to 27,000 sqm (290,000 sq.ft).
Why choose natural cork underlayment over synthetic alternatives?
Natural cork underlayment offers a unique combination of benefits that synthetic materials often cannot match: it is a 100% renewable and eco-friendly resource, provides natural cushioning through its honeycomb cell structure, requires no chemical additives for elasticity, and maintains breathability to support a healthier floor environment — making it an ideal choice for both performance and sustainability.
