FIBROUS LAMINATE FLOOR UNDERLAYMENT WITH IMPROVED ACOUSTICAL INSULATION AND BREATHABLE BARRIER PROTECTION
The present invention relates to a floor underlayment that may be positioned directly in contact with the underside surface of a finished floor and comprise more than one layer such as a first layer pattern-unbonded nonwoven web and a second layer microporous film. Additional layers may comprise a meltblown nonwoven layer and a spunbond layer. The floor underlayment of the present invention may exhibit a sound pressure level (SPL in dB at 800 Hz or 1600 Hz) reduction IIC of about 30 to about 40.
