Underground ductwork design
Underground ductwork design
(OP)
Does anybody have any suggestions for underground ductwork materials. What type of material is best. How do you prevent a condensation problem within the ductwork. Are there any useful guidelines for the overall design of the underground system. Any information would be greatly appreciated.
