here is an interesting take on an outside air kit. It's almost the same in wether to insulate a liner or not....next year the same information will change again

Thanks for this, not sure I am sold yet, but appriciate it.

Now about the liner - are you suggesting not to insulate it?

Everybody you talk to will tell you to insulate. I chose to NOT insulate mine. Here is Why: My fireplace is in the middle of the house and only the top 5 feet will stick out above the roof line and be exposed to colder temperatures. My chimney sweep/installer said he will insert rock wool above the damper and in the last 5 feet of the chimney, thus creating a dead space of air that is kept in the house structure it self. he said up until a few years he never insulated liners and never had a problem. Now all liner manufactures are reccomending to insulate.

My take would be that if your chimney is on the outside of the house and exposed to the direct outside air I would insulate it. The whole idea of insulating it is to keep the flue temps from decreasing to quickly and creating creosote.

Tough call... I saved $400 by not insulating

I have an outside chimney - so I might insulate (but might not). One more for you - how about a block-off plate, from these forums it appears to be a must have.

Thanks for all your time/help.

Outside chimney= insulate + block off plate

Keep in mind---I am not an expert, I have done hours upon hours of research and reading. It probably took me a year to finally make a decision
