Natural Cork: A Precious Material Derived from Nature
🌿 Eco-Friendly & Sustainable: Cork is sourced from the bark of the Mediterranean cork oak — a renewable, natural material harvested without harming the tree.
Cork is sourced from the bark of the Mediterranean cork oak and is a sustainable, natural, and eco-friendly material. We carefully select high-quality cork granules and use environmentally friendly processes to create a 2mm-thick cork base, preserving its natural texture and elasticity. The unique honeycomb cell structure of cork acts like countless tiny shock-absorbing airbags, giving the material its distinct resilience and responsive feel. This natural characteristic provides a warm, tactile experience and inherent sound insulation, offering gentle yet solid support for flooring.
Frequently Asked Questions
Q
What type of flooring is the CORK 20-AF underlayment compatible with?
The CORK 20-AF underlayment is designed for use with laminate, hardwood, bamboo, and vinyl flooring. Its natural elasticity and density make it a versatile choice across a wide range of flooring types.
Q
What are the IIC and STC ratings of the CORK 20-AF, and why do they matter?
The CORK 20-AF achieves an IIC (Impact Insulation Class) rating of 50dB and an STC (Sound Transmission Class) rating of 46dB. These ratings indicate excellent sound insulation performance — reducing both impact noise (footsteps) and airborne noise transmission between floors.
Q
Is the cork underlayment waterproof or moisture-resistant?
Yes. The CORK 20-AF has a water absorption rate of less than 0.1%, making it highly resistant to moisture. This ensures long-term performance and durability even in environments with moderate humidity levels.
Q
What is the thermal insulation value of the CORK 20-AF underlayment?
The CORK 20-AF has a thermal insulation value of 0.05 W/mK, meaning it effectively reduces heat loss through the floor. This contributes to a warmer underfoot feel and improved energy efficiency in the room.
Q
How is the CORK 20-AF underlayment packaged, and what quantities are available per container?
The product is available in roll sizes of 100 sq.ft and 200 sq.ft, and can be packaged nude, on pallets, or in cartons. A 20GP container holds approximately 12,000 sqm (129,000 sq.ft), while a 40HC container can accommodate up to 27,000 sqm (290,000 sq.ft).
Q
Why is cork considered an eco-friendly material for underlayment?
Cork is harvested from the bark of the Mediterranean cork oak tree without cutting it down — the bark naturally regenerates over time. This makes cork a renewable, biodegradable, and sustainable material. The production process also uses environmentally friendly methods, minimizing ecological impact.
