ROBERTS natural cork underlay is an extraordinary acoustic barrier for all types of flooring. In addition to being an eco-friendly option, cork is also a safe choice. It is naturally hypoallergenic and mildew resistant. Natural cork underlayment reduces sound transmission and helps protect floors from transferring stress cracks from the subfloor to the flooring surface. It also reduces thermal transmission, making it ideal for radiant heating systems. ROBERTS natural cork products can contribute to Green Building Program credits LEED.
