Cork underlay is supplied rolled and in various thicknesses. Rolls have a medium density and are bonded together with cork granules ranging from 2mm to 4mm.

Cork has unique acoustic properties that make it highly effective in reducing noise. Its cellular structure contains millions of air-filled pockets, which act as sound absorbers. When sound waves travel through the flooring system, the cork underlay absorbs and dissipates the energy, reducing sound transmission between floors and rooms from sources such as voices, music, footsteps, furniture movement, etc.

In addition to its acoustic benefits, cork underlay enhances the comfort and durability of any flooring. Cork's natural resilience provides a soft and cushioned feel underfoot, making walking and standing on the floor more comfortable. It also helps reduce strain on joints and muscles, particularly in areas where people spend a lot of time standing, such as kitchens and workspaces.

Cork underlay is also a barrier preventing moisture transfer from the subfloor to the floor planks. This helps to protect the flooring from damage caused by moisture, increasing its lifespan and durability.

Cork underlay is not only beneficial for its acoustic and functional properties but also for its environmental sustainability. Cork is a renewable resource harvested from the bark of cork oak trees, which naturally regenerate after each harvest. This makes cork underlay an eco-friendly choice for any flooring, as it promotes the preservation of forests and reduces the reliance on non-renewable materials. Furthermore, the production of cork underlay involves minimal energy consumption and does not release harmful pollutants into the environment. It is a natural and biodegradable material, making it a sustainable and responsible option for flooring applications.
