Composite foams are presented. They comprise a first rigid, microcellular, open-celled organic polymer foam having a density of from about 0.015 g/cm{sup 3} to about 0.20 g/cm{sup 3} and a pore size of from about 1 micron to about 30 microns. The first foam containing a second polymer having a density of from about 0.015 g/cm{sup 3} to about 0.20 g/cm{sup 3} or a second polymer foam having a density of from about 0.015 g/cm{sup 3} to abut 0.20 g/cm{sup 3} and a pore size of from about 0.01 microns to about 1.0 micron within the open cells of the first foam.
