Improve the air quality in your home with QEP's Natural Cork Underlayment. This environmentally-friendly cork underlayment is naturally hypoallergenic and contributes to a healthier indoor air quality. It also reduces sound transmission and makes an excellent sound barrier for all flooring types. This cork underlayment protects your floor against stress cracks transferring from the subfloor to flooring surfaces， and reduces thermal transmission， making it ideal for radiant flooring.
