Non-metal Duct Board


Anyone use Certainteed ToughGard duct board or any another non-metal product made recently?

Looking at the posts on "duct board", most of those posts were years ago and look like they are based on older / fiber duct.

Looking at their information Toughgard it is resin bounded fiberglass, so rigid and not like the fiberglass of old days, and it has a "lifetime" warranty.

I've heard they are used a lot down south and "if installed correctly" they work well... But, want to see if anyone has any direct experience with it since marketing materials/people tend to lie in my experience.

Re: Non-metal Duct Board


Duct board is fine. Could be handy under certain situations. My hesitancy would be about the condensate piping.

Make sure the condensate is piped so that it drains well. Heck, just use a condensate pump, and you probably would be alright.

I have been in many homes in which drainage was less than adaquet. As a result, the liquid overflows into the ductwork. That fiberboard, when wet, wont dry out, I believe will be a major source of mold....That's the thing to beware of.

That specific product indicated it is treated with an anti-mold/mildew agent (so maybe that would help from that perspective anyway) - but - yes, that is a good point about condensation. Thank you.

Re: Non-metal Duct Board


I wouldn't want to use it as my go-to, at least here. But, I can see times in which, it may be a good way to go. Just I don't like those fibers.
