I am sealing my ducts with mastic. However, there is one area that I can't
reach between the duct and he subfloor. I can feel a cold air draft up
there fom the AC. Since I can't reach it, would it make sense to spray some
of that Dow "Great Stuff" foam up there and let it expand and seal it?
My ducts are galvanized, circa 1965. Thanks.
No one's sober!!! Joke??? Sorry for leaving out a :)
Agree about reading etc.. and my opinion is that homeowner ???s can be
elsewhere not here. That is my opinion and I do not respond to homeowner
I didn't tell you not too or how to post anything??? I do however put my
two cents in when I have time to post.
Is this a HO help forum??? Debatable yes but I say no it is not.
Bullshit no, mooseshit maybe... :)

galvanized tin meets building code, expando-foam doesn't.
I'd be real leery of the expando-foam approach, especially if it
outgasses formaldehyde or other toxic/carcenogenic etc vapors.
Pull the grill and seal from the inside, as far up/down as you can
