Will DuctSox condensate?
Yes and no depending upon selected fabric. Non-porous DuctSox fabrics will condense if the conditions are right. Porous DuctSox fabric will not to condensate because the airflow pattern around the DuctSox keeps the warm moist air off the walls of the DuctSox. As a rule of thumb, if single wall uninsulated metal will condensate, so will non-porous DuctSox fabrics.
