Would be interested to learn of any viable and code-acceptable alternatives to metal ductwork plenums for air conditioning.

Some space pac installs are done with a smaller duct size flex material, they run at a higher static and velocity.

The supply is usually a rigid duct, and the return is sound atenuating.Originally posted by fat eddy

Duct board is okay for use in our area, and I'm familiar with the flex duct. But, am concerned about the potential for mold growth with the fiberglass duct board...and the flex duct won't work for the main plenum.

If the name sawdust means anything about what might be in the air around the units, I would use metal only. Lol

why dont you want metal ducts, insulate them and you are good to go.. sorry to say in Az we use flex-duct it does the job, but I prefer sheet metal it lasts longer and doesnt collapse on you. flex-duct is not up to code in all areas so check your local codes first... good luck...
