What material could I use to fill the space (1/2 - 3/4 in.) between the range hood vent pipe (galvanized metal) and the wood of the kitchen cabinets?
The pipe goes up into a plenum and then is ducted outside, but the plenum is vented to the outside of the building and cold drafts (and maybe mice) find their way into the kitchen. Someone suggested stuffing the space with steel wool, but I'd like to use something more compatible with food and dishes. The space isn't big enough to try to fit a piece of wood around the vent pipe.
Thanks, TKM
