| I have large hole in my heat duct, where I removed an usused feeder duct. It is about 12" x 8". What is the best way to seal this. I currently have cardboard duct-taped to it. Should I just put a piece of sheet metal over it with some duct mastic as adhesive?
Thanks. |

| A few fasteners would be a good idea. 1/4 inch long self tapping sheet metal would be fine. |

| you don't want cardboard in this area. go to a sheet metal shop and purchase a piece of insulation and a piece of sheet metal sized slightly larger than opening. put trim the insulation to fit the sheet metal use the 1/4" self tapping sheet metal screws to attach well. then mastic seal. best of luck. |
