Hey all,

I know this has been talked about a lot in the forums. However, I am getting ready to get my Lopi insert and the place that I am getting it from said they only carry non insulated liners. They also told me that an insulated would not really be necessary as my fireplace and chimney are interior and in the middle of the house. Is any of this true, or should I order an insulated anyway online to install?

Thanks,

Bob

It should be insulated, and now is the time. A lot of dealers says it’s not necessary, but they are incorrect.

I wish that I insulated mine better... Mine is also a flex liner in a clay liner that is in an interior brick chimney.
If I was you I would insulate it as good as you can!

Code requires an insulated liner if the chimney has less than 2" clearance from any combustibles all the way up through the house.

Are there any companies you recommend? I have seen a few mentions of Rockford chimney for liners?
No specific recommendations but maybe others on here can chime in. But one theme on this forum is to stay away from the so-called double wall liner. All it is is a lightweight liner with an inner stainless layer that is prone to getting chimney brushes hung up on it. I had one in the past and it was ok but the install I thought was shotty so I had it replaced.
 
More work. The terra cotta liner needs to be broken out, it’s heavier to lift and install, and since the inside of the chimney is rougher, it’s more apt to get caught on things going down.

I’m not sure what the markup is on them, but it might not be worth the frustration factor to some.

There’s also the possibility that they don’t know code and legitimately think they are doing right by saving the customer money.

I’m not sure which option is the best, each train of thought has its pitfalls, but I try to hope that people are always trying to do right by the customer.

I am curious why they tell people that. I mean the insulated are more expensive so I figure they would make more off them. Maybe slightly harder to install?
To keep prices down to make the sale and to keep the installs quick and easy
