    What is cork and how is it environmentally friendly?

    ecoCORK Insulation Acoustic Underlay is simply the world’s best underlay, in every way possible. From its naturally and sustainable sourcing through to its ease of use, acoustic performance, thermal benefits, energy ratings and even the improved performance of the entire floor system. ecoCORK Insulation Acoustic Underlay provides benefits like no other underlay on the market.

    Just like bark on a tree, cork’s natural protection and benefits translates into benefits for us and our environment, including the performance of the floor as well. It does this by being a complete insulation layer, filled with millions of tiny cells in a sponge like structure. ecoCORK is produced from a blend of specialised different sized Cork grains. These specialised Cork grains are then compressed to a certain density to maximize the products insulation and acoustic performance. This natural product is then made into sheets and installed with many different types of floor coverings. The main benefit of course, to provide a peaceful environment between apartments and improving the environment overall.

    All of this whilst being non-toxic and the only true environmentally friendly underlay on the market. The perfect match to your new floor.

    ecoCORK is also lightweight making transport and handling of the product on site easier for the installer. ecoCORK can either be floated over the sub-floor or direct stuck using a number of different methods and brands to suit many different floorcoverings. ecoCORK is available in a range of thicknesses to suit varying projects and can even be specifically created to suit your project.

    Cork has always been known for its incredible natural benefits, including acoustics for the building industry. This is why Cork underlays are the preferred choice and installed regularly throughout entire apartment complexes world-wide. Cork, a sustainable product grown mostly in Portugal has always been hard to source to Australia, a country very far from its origin. ecoCORK, developed over 15 years in Australia, bridges this gap bringing the very best in technology and cork products from Portugal.

    Cork is another wonder in this field having the highest thermal performance per thickness than any other natural product and almost all synthetic products on the entire market.

    The natural cells in the Cork bark provide the perfect and natural resistance to heat transfer, just like it would as bark on a tree to survive the Portuguese dry heat.

    • ecoCORK Thermal Resistance (R-Value) of 0.137 (0.137m2°K/W) EN 12667 - 0.3 per square inch
    • ecoCORK Thermal Conductivity l-Value of 0.0038 W/ mK EN 12667

    ecoCORK Insulation Acoustic Underlay has also been successfully tested in accordance with AS ISO 9239.1-2003 C1.10
