  • Hybrid underlayment for non textile floor covering
    Patent number: 11130317
    Abstract: A hybrid underlayment including a compliant material layer and a rigid material layer affixed to the compliant material layer. The compliant material layer exhibits a compression deflection as measured according to ASTM standard D-1056-14 in the range of from about 0.14 kilogram force per square centimeter to about 1.76 kilogram force per square centimeter, and a thickness of at least about 2 millimeters. The rigid material layer exhibits a thickness of at least about 0.5 millimeters and a flexural modulus of at least about 600 MPa and flexural strength of at least about 35 MPa in both the length and width directions, both flexural modulus and flexural strength as measured according to ASTM D790-17.
    Type: Grant
