Wet fiberglass ductwork

in THE MAIN WALL
Hi Everyone, I had a leak in a pipe under the sink in our kitchen and it flooded the first floor and the basement. I have filed a claim with our insurance but haven't talked with them yet. My concern is does the 12 foot section need to be replaced to prevent mold? I poked a hole in it and drained approximatley 15 gallons from the ductwork. Should I insist on it being replaced? My gut is telling me it will dry out when I run the forced air system, but I don't want moisture damaging something in the furnace. I need a little guidance and some reccomendations. Thanks for your input. Roger

    I've read and have been told that fiberglass becomes ineffective and should be replaced anytime it has been saturated with water.

    I've seen it first-hand after fire or flood. Even after drying it's compressed and is never again fluffy--and it's the "fluff" that allows it to insulate.

    Cut it out

    Replace it with Insulated metal duct work and install a uv lamp at the furnace to kill any mold (If you have water damaged fiberglass ductwork you have mold.) We cut out a lot of fiberglass duct work and none of it is any good. Best Wishes J.Lockard
