There is an old wall cap for a range hood vent in my house. Seems like the range location was moved when the kitchen was redone, and they installed a ductless hood.
I am installing a new ducted hood and would like to use the old cap.* It's at most a 5' run of duct total, but if I used rigid I would need to use 3 90°s (2 of them back to back) since I need to jump over a joist bay.
It needs to go up into the cabinet, 90° over to the right, 90° up into the joist bay, then 90° out to the vent cap.
Should I go with rigid w/ 3 90°s, or a continuous run of semi-rigid?
(I know ideally I'd just go straight out the back of the hood through the wall w/ a 10x3-1/4 rectangular duct, but this is just a kitchen facelift rather than a full reno. I don't want to make another penetration in the exterior wall especially considering it's brick.)
