DuoFoam with Self Seal is an underlayment that combines PolyFoam to low or high density polyethylene film to create a vapor/moisture resistant floor. DuoFoam™ with Self Seal can be used over concrete slabs, or other surfaces that may damage a laminate floor due to moisture content. DuoFoam with Self Seal is a stronger underlayment that offers all the benefits of PolyFoam.

For a quick and easy installation, DuoFoam™ with Self Seal has an overlap of film on one edge, with a peel and stick tape strip along the other, making it a very user-friendly underlayment that reduces installation time. DuoFoam with Self Seal also laminates film to both the top and bottom of the underlayment, for twice the amount of protection.
