Natural Cork Underlayment Sheets - 6 mm - 300 sq. ft. (50 sheets)

ROBERTS Natural Cork Underlayment is an outstanding sound barrier for all types of flooring. It reduces sound transmission, and helps to protect the floor against the transfer of stress cracks from the subfloor through to flooring surfaces. It also reduces thermal transmission, making it ideal for use with radiant heat systems. Easy to install in both glue-down and loose lay configurations, it is naturally hypoallergenic, mold and mildew resistant. ROBERTS Natural Cork products are FloorScore Certified for healthier indoor air quality and may contribute towards satisfying credits under the LEED Green Building Program.
