  • EnduraDuct follows SMACNA minimums but can increase the gauge if needed.

                       
                                       Can EnduraDuct be pressure tested in the field?
  • The interior of EnduraDuct is made of SMACNA rated sheet metal ductwork. Thus, pressure testing EnduraDuct is no different than pressure testing any sheet metal ductwork built by any sheet metal contractor.

  • The insulation and coating of EnduraDuct provides extra protection against air leakage.

 
                          Can curbs be insulated and coated with the EnduraDuct system?
