🌱 Natural Cork: Returning to the Essence of Comfort and Protection
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.
✅
Key Benefit: Natural honeycomb microstructure provides superior cushioning, elasticity, and breathability — no chemical additives required.
❓ Frequently Asked Questions
💬
What is CORK 20-P and what flooring types is it compatible with?
CORK 20-P is a 2mm natural cork underlayment designed for use with laminate, hardwood, bamboo, and vinyl flooring systems, particularly those installed over radiant heating systems. Its low thermal resistance (0.05w/mk) ensures efficient heat transfer.
💬
What are the sound insulation ratings of CORK 20-P?
CORK 20-P achieves an IIC (Impact Insulation Class) rating of 50dB and an STC (Sound Transmission Class) rating of 46dB, making it an effective solution for reducing both impact noise and airborne sound transmission between floors.
💬
Does cork underlayment require any chemical additives or adhesives?
No. The natural cork granules used in CORK 20-P are gently compressed to form the underlayment layer without the need for chemical additives. This makes it an eco-friendly and safe choice for residential and commercial flooring installations.
💬
How does the honeycomb structure of cork benefit flooring performance?
Cork's natural honeycomb microstructure acts like millions of tiny springs, distributing pressure evenly and absorbing impact energy. This provides excellent cushioning underfoot, reduces fatigue when standing, and helps protect the flooring surface from damage over time.
💬
What is the water absorption rate of CORK 20-P, and is it suitable for moisture-prone areas?
CORK 20-P has a water absorption rate of less than 0.1%, which is extremely low. Its breathable structure also prevents moisture from being trapped beneath the floor, reducing the risk of mold or warping in areas with moderate humidity.
💬
What packaging options and load quantities are available for bulk orders?
CORK 20-P is available in three packaging options: Nude, Pallet, or Carton. For bulk shipping, a 20GP container can hold approximately 12,000sqm (129,000sq.ft), while a 40HC container accommodates up to 27,000sqm (290,000sq.ft), making it highly efficient for large-scale flooring projects.
