What is this gasket material used on my stove?

[Rob_the_Sparky]

I'm doing a bit of maintenance on my stove (Clearview Pioneer, new insulation and baffle plate) and found that the bar at the back has a sealing material between it and the back of the stove.  It is an emissions control stove so has a bar above the back board that lets in ait just below the baffle plate and feed from two square holes in the back of the burner.  Anyway, there is a fine white almost felt like material used to prevent air leaks from these ports into the bar that has seen better days.  It also appears to have been used to seal the cover plate for the unused chimney output in the back of the stove.

 

Can anyone advise what this material is as no where can I see anything like this listed in the spare parts lists for clearview (or stoves more generally TBH).  I suspect it is some sort of generic gasket material but not being in the industry I do not know what I'm asking for TBH.  I'd guess it is 1 or 2mm thick, white, felt like to handle and clearly high temperature resistant given it is almost in the firebox.

can you share pictures, I'm finding this hard to visualize.

It sounds like that flat glass fibre tape that some manufacturers use to seal glass. I think you can get self adhesive types as well

Does this help?  This is the back of the bar that distributes the air showing the sealing material, which as you can see is no longer sealing very much.

I'd describe as something between felt and a sheet of cotton wool.  It is VERY weak and will tear super easily.

kaowool or cerablanket, it can be fixed on with a proprietary waterglass based glue but Holts gungum exhaust paste is similar. I think I may still have a part roll of it.
