I'm installing a used paint booth in my hangar. It came with some ductwork that went straight up and out the side of the building. My hangar is leased so I can't cut an opening in the wall. I rearranged the duct to what you see here. Now I need to connect the upper duct to the window exit. I've thought about just duct taping some insulation board together with 1x2 supports but am concerned about the volume of air I'm moving. The 24" tubeaxial fan is supposed to push 7900 CFM. The sheet metal duct is 22x22". Anyone have experience with something similar or HVAC folks want to comment. I'm open to suggestions. Thanks.
