2018 HPC National Conference Session

The Joy of Flex

Tuesday, April 24
1:30 PM - 3:00 PM
Location: Franklin 4 (4th Floor)

Getting good air flow in even the best duct materials isn’t easy. It requires design, skill, and patience. When it comes to flex duct, however, those three qualities are often absent. Allison Bailes and Mike MacFarland will show you the contorted results, explain the problems, and describe how flex duct should be run. They’ll also discuss the physics of air flow, including how flex duct compares to rigid sheet metal, and show you how to make flex duct systems work in the real world.
