Floor covering underlayment

摘要

A flooring installation is characterized by installing an underlayment between the flooring material and the subfloor. The underlayment includes a polymeric layer, preferably a foamed polymeric layer, and a fiber mat, preferably a glass fiber. The foamed polymer interpenetrates at least the lower portion of the glass mat. A portion of the fiber mat is preferably unsaturated. The fiber mat may have an acrylic latex tie coat opposite the foamed polymer layer.
