Hello all, My wife and I are having a little disagreement about one of my diy'ers project. I had to install a new range exhaust and install new venting duct. I took out the old duct and covered up the opening with vinyl siding, and stuffed some insulation in it from the inside. my wife says that I should have covered up the opening with something more substantial. the opening is only about 10"x3-1/2" she says that base on the home improvement shows that she has seen she is concern about my less than perfect finishing work. thanks all
