Abstract
An easy-to-install flooring underlayment 10 with improved tear resistance and tensile properties is disclosed. The flooring underlayment 10 has a first layer 12 and a second layer 14 with a plurality of cell-like openings 20. A plurality of the cell-like openings 20 have a surface opening or a cross-sectional area (A) of at least 2.5 mm2. Both the first and second layers 12, 14 may be made of polymeric materials, and the second layer 14 may be in contact with the first layer 12, connected to the first layer 12, integral with the first layer 12, or embedded in the first layer 12.
