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.
Frequently Asked Questions
Q1
What type of flooring is the CORK 20-P underlayment compatible with?
The CORK 20-P cork underlayment is compatible with a wide range of flooring types, including laminate, hardwood, bamboo, and vinyl flooring. It is especially well-suited for use with underfloor heating systems due to its low thermal insulation value of 0.05 w/mk.
Q2
What is the thickness and density of the cork underlayment?
The CORK 20-P underlayment is 2mm thick and has a density of 220 kg/m³. This combination provides effective cushioning and sound absorption while remaining thin enough for use under most flooring installations.
Q3
What are the IIC and STC sound ratings of this cork underlayment?
The CORK 20-P has an IIC (Impact Insulation Class) rating of 50dB and an STC (Sound Transmission Class) rating of 46dB. These ratings indicate strong performance in reducing both impact noise (such as footsteps) and airborne sound transmission between floors.
Q4
Does the cork underlayment contain any chemical additives?
No. The cork underlayment is made from 100% natural cork granules derived from Mediterranean cork oak. It does not require any chemical additives to achieve its excellent elasticity and cushioning properties, making it an eco-friendly and safe choice for residential and commercial use.
Q5
Is the cork underlayment breathable? Will it cause moisture problems?
Yes, the natural cork underlayment is breathable. Its honeycomb microstructure allows air circulation, creating a "breathable" protective layer between the subfloor and the flooring surface. This helps prevent moisture retention issues that can sometimes occur with fully sealed underlayment products.
Q6
What are the available roll sizes and container load quantities?
The CORK 20-P is available in roll sizes of 100 sq.ft and 200 sq.ft. For bulk shipping, a 20GP container can hold approximately 12,000 sqm (129,000 sq.ft), while a 40HC container can accommodate up to 27,000 sqm (290,000 sq.ft), making it a practical choice for large-scale flooring projects.
