Confusion around chimney liner

[apbarker]

Hi all. Long time listener first time caller.

I'm purchasing a Blaze King Sirocco 25 to insert in my existing masonry chimney. I am currently trying to order and install the liner. It's a straight shot down from the top of the chimney and I will be cutting through my damper for the install. I need a 25' liner.

I have read many people on this forum say that 1) 2ply liners are no good, 2) .006 thickness liners are not ideal, 3) smooth wall liners aren't great, and 4) Rockford is a good supplier.

However I just talked to Rockford and they told me that:
-their thickest corrugated option is .006
-their .010 thickness option is smooth walled and 2ply

So, their offerings seem to run against the conventional wisdom I've encountered in these threads.

Am I misunderstanding - would one of the Rockford options be fine?
Or, can someone link me to a corrugated, 1ply, 0.10 liner option?

Thanks for any help!

Chimneylinerdepot is telling me the same thing - their thickest 1ply is .006.

I just called them, but they only work with certified chimney sweeps. They suggested I order through one of their clients who could drop ship to me...but the client they recommended is Rockford, who doesn't have what I'm looking for.
