ABSTRACT:
A flooring system having a top floor layer, a sub-floor, and an underlayment material disposed between the sub-floor and the top floor layer is disclosed. The underlayment material may include a cross-linked, polyolefin foam having a moisture vapor transmission rate of less than about 3.0 lb/1000 ft2/24 hr, and an average sound pressure level of less than about 15 dB over a range of about 300 Hz to about 1000 Hz. The foam may have a compressive strength of at least about 0.85 kg/cm2. Foam density, gel fraction, and resin blend may combine to provide an underlayment material having such reflective sound and moisture vapor barrier properties.
