persoanally all that we instal for wood stoves is heavy flex liner but there are also very many good light wall flex liners out there to. I just feel the extra thickness of the heavy wall is worth it. The only one i would absolutly stay clear of is the double layer smooth wall stuff

Check out insulated double wall rigid also. Costs more, but worth every cents as far as I am concerned.

What is the issue with double wall smooth? Does it perforate too easily or?
So many liners out there it's pretty confusing.
Can you name some names and suppliers?
The liner that I think Hogwildz is referring to is DuraLiner. It is pre-insulated and comes in a variety of sections including rigid, flex, oval and round.

There are several tyes of liner to consider. First choice is rigid or flex. Rigid is very durable but can be a real pain to install in my opinion and if there are any offsets it is next to impossible but if it is a straight shot it works well. In flex there are several types there is heavy wall which is .018" with what is classified as a smooth wall interior that is my preference for wood but it is expensive. There is now a mid weight liner with the same interlock smooth wall construction as the heavy wall but out of .010". Then there is light wall that is .006" or .008" it is usually a crimped seam (although ventinox is welded seam) it is probably the most commonly used liner it is fairly cheap and holds up ok as long as it isn't abused. he double layer smooth wall stuff has a second thin layer on the inside i feel that it is a real pain to install without kinking that inside layer and it is very thin and easily snagged with a brush when cleaning i would not recommend it personally. As far as brands as long as you buy from an established manufacturer and it is ul listed it should be ok.
Oh i forgot to add about insulation. There are preinsulated liners like the duraliner mentioned earlier and there are also preinsulated flex liners with either light wall or mid weight interior liners. Or you can insulate regular liners with insulation wrap with pour in insulation which is a mix of vermiculite and cement that you mix with water. For a diy job either preinsulated or wrap is probably best.

Good info - thanks ... can you clarify for me the difference between "heavy wall which is .018" with what is classified as a smooth wall interior" and "double layer smooth wall stuff has a second thin layer on the inside" - you seem to be suggesting one good version of smooth wall and one bad, how do you know the difference - is it strictly a thickness issue?
I notice very few of the online stove pipe suppliers seem to offer thickness descriptions up front in their online ads. I assume one has to attempt to verify by further phone questioning, what their offerings are in thickness?
304L versus 316?

The 2 different smooth wall liners are vastly different the heavy wall is one layer thick and the joint iz interlocking while the other is two layers the outer layer is similar to regual light wall with a crimped seam then the inner layer is very thin peice that just over laps the previos layer leaving one edge free. For wood either 304 or 316 will work just fine 316 is needed for oil gas or coal
well I am going to need a flex liner. the chimney has an enormous cement cap that doesn't come off....plus I think getting it thru the damper would be an issue. sounds like 316 is way to go
How are you planning on getting the liner in i doubt it will flex enough to do it with the cap on you might be able to cut a hole in the top big enough to drop a rope through and pull it up. But we would usually pull the cap to do it.
well I have considered this. I have 14" above the flue to the cap...the flue is big....18 x 18 or 18 x 20...cant recall what I put in there...I am hoping I have enough room and enough flex in pipe to make the bend, but if not, then bottom up is how i'll have to do it. either way, I don't see it being to much of an issue. I just don't want to have to do it again anytime soon because I skimped on the liner
ps- theres no pulling this cap....not without a crane

We have pulled some pretty big ones but if it is to big lots of times we will cut a hole in the top and drop the liner through. This also allows acces in the future for maintenance. We then put a stainless plate over it. You wont be able to flex it in through there i would say either cut a hole or drill a small one to run a rope through.
