"Pre-insulated" chimney liners?!

[brenndatomu]

In doing some research for a chimney liner for my new stove install, I came across this...(broken image removed)
Magna-flex Insulflex, I have never seen a product like this before, and I thought, hmm, I don't need this, but it may be just the ticket for someone that has a tight flue to work the liner down through. Especially so if you have broken flue tiles or a lot of sharp edges or mortar joints that would tear up a standard insulated liner on the way in. Listed as zero clearance too.
I did a search here on Hearth.com and found that although this product has been mentioned before, it's been a couple years, so I thought I would bring it to all the new guys attention.

Have it. Good stuff, IMO. About the same price as buying a liner and an insulation kit separately, but you don't have to mess around with glueing the insulation to the liner. There was some debate on here about the zero-clearance rating. . .dunno what the status of that is now, but it's not a requirement with my 12 x 12" chimney.

It's a good solution for simplifying the installation of inserts even if the chimney is larger. I also like M&G DuraLiner which is also factory pre-insulated and has a beefy .016 inner liner thickness, because they provide a whole system for just about any circumstance. This includes oval or round, rigid or flex, tees, etc. and the transition pieces to make it all work together.
