The present invention provides porous polymer coatings having adhesive and air flow resistive properties. The porous polymer coating comprises a polymeric foam having a void fraction of greater than about 15% and an air permeability greater than 3 cubic feet per minute per square foot as measured based on ASTM D737-04.

Porous polymer coatings

A moldable acoustic facing comprises cellulosic fibers and synthetic fibers entangled together. The acoustic facing has a basis weight of from about 1.5 to about 5.0 ounces per square yard (osy), a thickness of less than about 0.050&#x2033;, a mean pore size of between about 8 microns and about 40 microns, and an elongation at break of at least twenty percent. The acoustic facing includes less than about five percent synthetic microfiber and has an acoustic resistance of at least about 250 Rayls.
