 | 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. |
