Last night on "Ask TOH", they had a guy who showed how to seal FHA duct
work. Are there foil tapes available to a homeowner that are very high
grade? Is the stuff at the BORG good enough to do the job?

One more...this is heating season in NE. How long does it take for duct
sealing mastic take to dry?

Thanks.


As was explained to me, the tape should be UL-181 rated. I dont know
if you have a Menards in your area, but I bought a roll there. They
had both UL spec'd and non-UL spec'd tape. Regular foil tape was
approx $5 per roll, UL-181 rated tape was approx $15. The tape has
the word "UL-181" printed all over its surface.
