Improve the air quality in your home with Capitol Natural Cork Underlayment Sheets. These environmentally friendly are ideal for reducing sound transmission from upper levels to lower level living spaces. These cork underlayment sheets can be used under ceramic tile, porcelain tile, stone, marble, engineered hardwood and laminate floors. They act as a crack isolation membrane that resists the transfer of cracks from the subfloor into cracked tiles on the finished floors. It reduces thermal transmission, increasing the effectiveness of floor heating systems. Capitol Natural Cork may contribute towards satisfying credits under the LEED Green Building Program.
