sszalay Posted May 19, 2014 Report Share Posted May 19, 2014 I remember hearing an inspector on a web video (though I can't find it now) say that the heating duct in a newly finished basement that comes down through the external wall, through the top plate, of a steel studded wall, has to have "cold air ground and firestop bonded." I have a similar situation in a basement I'm doing and I know what firestopping is, but I can't find anything on "cold air ground". Can someone point me in the right direction. I'd appreciate it. Thanks. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted May 20, 2014 Report Share Posted May 20, 2014 I have no idea. It's a jumble of meaningless words. Whatever your project is, get a permit, have the plans approved, and get the work inspected. Don't use internet videos to learn how to finish your basement.
