QEP's Natural Cork Underlayment is an outstanding sound barrier for all types of flooring. Besides being an environmentally friendly option, cork is also a healthy choice. It is naturally hypoallergenic and contributes in creating a healthy indoor air quality. Install like a professional by using ROBERTS Cork Adhesive and ROBERTS Seam Tape. Natural Cork Underlayment reduces sound transmission and helps 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 radiant flooring. QEP Natural Cork products may contribute towards satisfying credits under the LEED Green Building Program.
