I’m wanting to redo a kitchen in an 81 year old hold with structural brick walls. I would like to vent the new range hood with an approximately 11″ X 5″ rectangle hole through an exterior wall. Will I need to install a ledger or is the opening small enough to not need one? If so – what kind will I need? Also sincet his will have heated exhuast fumes from a high btu stove, what would be the best material to fill in around the hole to help keep air from penetrating?
All help is appreciated!

Will I need to install a ledger
probably not.
the best material to fill in around the hole
metal duct and the "end cap" that will have a flapper to prevent air from coming back into the duct-birds, etc.
Why not transition to a round duct so that you can cleanly and neatly core drill through the brick? Much easier and no real gap to fill.
