Natural Cork: A Precious Material Derived from Nature
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 is the CORK 20-AF underlayment made of, and what flooring types is it compatible with?
The CORK 20-AF underlayment is made of polyethylene combined with natural cork granules. It is compatible with a wide range of flooring types, including laminate, hardwood, bamboo, and vinyl flooring, making it a versatile choice for various installation projects.
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 the underlayment's ability to reduce both impact noise (such as footsteps) and airborne sound transmission between floors, making it an excellent choice for noise-sensitive environments.
Q
How thick is the cork underlayment and what is its thermal insulation value?
The cork underlayment has a thickness of 2mm and a thermal insulation value of 0.05 W/mK. This low thermal conductivity helps retain warmth underfoot, contributing to a more comfortable indoor environment and improved energy efficiency.
Q
Is the cork underlayment resistant to water absorption?
Yes. The CORK 20-AF has a water absorption rate of less than 0.1%, making it highly resistant to moisture. This low absorption rate helps protect your flooring from potential water damage and ensures the underlayment maintains its structural integrity over time.
Q
Where does the cork material come from, and is it environmentally friendly?
Cork is harvested from the bark of the Mediterranean cork oak tree. It is a sustainable, renewable, and eco-friendly material — the bark regenerates naturally after harvesting without harming the tree. Environmentally friendly processes are used to produce the 2mm cork base, preserving its natural texture, elasticity, and unique honeycomb cell structure.
Q
What container load quantities are available for bulk orders of the CORK 20-AF?
For bulk purchasing, the CORK 20-AF is available in the following container load quantities: a 20GP container holds approximately 12,000 sqm (129,000 sq.ft), while a 40HC container holds approximately 27,000 sqm (290,000 sq.ft). The product is available packaged as nude, on pallets, or in cartons to suit different shipping and handling requirements.
