How to insulate a SS stove liner?

suisidevw

As above please, how is this completed?

What is done with the vermiculite etc? Surely not poured down the actual liner?

Many thanks in advance.

My understanding is that the vermiculite/leca sits between the outside of the liner and the inside of the chimney.
I assume doing this means that removing the register plate is then out of the question.
I would also think it makes the liner easier to sweep as it should make it more stable?

There is a "jacketing method" for the liner that you can use which looks a bit like the stuff that wraps around copper piping.
This is then "joined" using a specialist type of tape.

I've never seen it done in practice but that is my interpretation of what i've read.

I also assume that it is a good idea to make sure the chimney isn't breached if using Leca.

WOW, That would be many bags of vermiculite if it is poured from between the liner and the chimney..... can anyone confirm this?

Very interesting. Thanks

Right tool for the right job.
In a narrower chimney i assume they recommend the leca backfill as it is cheaper.

In a large chimney i'd assume they recommend this stuff:-

Hi, we use vermiculite or rock wool wraps. In thatched properties we have to use 50 mm rockwool wraps.

Confirmed.

It doesn't use too much, I have a tallish stack - about 10/11 metres - and I used 5 bags exactly at £15 a bag.
