Arch your ductwork is a piece of art, who ever made those has his stuff together. I had no problem with nothing between the intake and exhaust of the mini splits all summer but did notice it was hot in that bay so this should cure that.

Thanks Simon, you fabricate a lot and if you ever need something strong and lite I recommend that sign board, not cheap $220 1/4" thick 4x8 panel.
