I need to install 3.25 x 10" duct for the new downdraft cooktop. Do I screw the joints together, or is there some other way the sections join? I read something online about some kind of clips but that sounds kinda flimsy.
Should I tape or use some sealer/mastic?
This will go up an exterior wall. Should I try and use fiberglass batts between the sheathing and duct? Obviously I'll have 1/4" of space to work with.
What about condensation? This will run under the cabinet for a couple of foot and then up the wall and out the roof. There is no where for condensate to drain. Should I just insulate well and hope for the best?
Anything else a ductwork/HVAC newbie needs to know?
Thanks
