I've got 2 bids to replace my current duct board transition which is falling
apart. One contractor's bid is for a sheet metal transition (that I think
is being custom made) and the other contractor's bid is for another duct
board transition. The cost difference is minimal. Ever since I moved into
this house, there have been problems with the duct board transition. It
constantly leaks and is being retaped on a yearly basis (that is the reason
it is finally being replaced). The "duct board" contractor says that his
installation crew builds the best duct board transitions around. He claims
you can sit on them and they use a more flexible, longer lasting material
than hard cast on the joints. They are warrantied to not leak air for 1
year. He also claims duct board is easier to work with when servicing the
evap coil and that he also has experienced the insulation coming loose from
the inside of sheet metal transitions and causing the evap coil to freeze
Anybody out there have an opinion on this subject? What is the preference
in a retrofit situation? Thanks in advance for your responses.
Sheetmetal,and nothing else.
Ductboard is absolute shit...period.
I have an installation that we are working on now, that the entire system
was made of ductboard. I offered to replace it, and price was not an option,
but the transitions here,will be of metal...period.
