Liner Supplier/Sale/Thoughts

[DeepSpringFarm]

I'm sure you guys are tired of answering these types of questions...

Looking to get a liner for a Progress Hybrid (probably). Had a chimney sweep out last week and he said my masonry chimney looked good to go. It is interior to the house, masonry, and 12"x12" and approximately 22 feet in length.
1. What should I look for (probably Stainless Steel insulated, but what grade SS?)
2. Who is a good supplier of liners?
3. Does anyone know of a sale going on right now that I can take advantage of?

I also have a full chimney bird cap on which has the top about 4" above the terra-cotta liner, I imagine I will have to remove this. This chimney also has another flue that goes into my basement which I believe is 6x12" at the top. Both of these are present on the top of the chimney but separate flues.

Gracias!

Ok, so when I go to woodlanddirect I see that they have multiple options.
304 and 316. Easy flex Vs. Heavy Flex. Smooth wall vs not?
Is it hard to insulate a liner, or should I go for a preinsulated liner?
I want to get whatever is going to last the longest and be safest in my house.
Does anybody have a preference on top cap and why?
Thanks!

There are a lot of liner companies on the internet and other companies that sell liners along with other vent pipe. Here are a handful to start with.

If you are going for longevity put in the heaviest gauge liner or with a large chimney consider putting in a rigid liner that you pop-rivet together as you lower the sections. DuraLiner by DuraVent has a nice preinsulated rigid liner system for this. This is my favorite with a large throat chimney like yours. You have plenty of room so I would just get an insulation blanket kit for the liner, but if you want an all in one package, Forever Flex by Olympia is a good quality product.

What is the advantage of a rigid liner? What do you do with the bottom section where you have to bend it a bit, use flex liner?

We never use rigid liner anymore all we use is flex. For wood we use heavy wall flex or occasionally the midweight flex. And for wood all you need is 304 grade. I feel all liners should be insulated it is your choice whether you go with preinsulated or insulate it yourself.

A rigid liner is tough and smooth. The one we had was heavy gauge and bullet proof. At the bottom it depends on what is needed and how much wiggle room there is. Sometimes an offset can be achieve with an elbow or two, but often switching to flex through the damper is the easiest solution.

FWIW, our local sweep still puts in rigid if customers ask for the best and longest lasting.

Flex King HD at Chimneylinerdepot? Is it worth the extra money? Does anybody have thoughts on this?
Should I go with a smooth wall? Just called a few companies and I have gotten about a range from the mid $500 up to almost $1000 for the set up.
This is for a 25 foot stainless set up. shipped to my house.

Never used it but it looks like nice heavy liner. Skip the smooth-wall 2 plys, folks report they can pucker on the interior.

Here is the announcement for Flex King HD.

Well some of these discussions make me nervous about a smooth wall liner and their integrity.

It's the 2 ply stuff I would avoid. Single-ply heavy duty should be ok.
