Sealing Around Fan Vent Pipe
As the pictures show, I need to seal around this kitchen fan vent pipe. Insulation has fallen five feet down the opening which I will need to vacuum out.
Plan is to place drywall within 1/2" of the pipe to cover the opening, then spray foam (orange fire) the gap. Is this allowed?
