flue liner for timber frame properties

[johnnyplumb]

Anyone know where you can get purpose made flue liners . 4" boiler flues need a 6" liner. Tryed a few merchants but no joy. Ended up making one out of sheet metal. Would be alot easier if you could buy them.

make one with asbestolux sheeting or a blank gas fire back plate.

used clay pipe before for liners but its not ideal for cutting or carrying around. surely purpose made liners in metal must be available somewhere.
