Bottom of the chimney flue is mounted on the floor beam using load bearing insulations blocks having 12 No of load bearing dowel pins (Syndanio NA material) as shown above. As Syndanio NA has got good compressive strength with low thermal conductivity, it is best suited for such type of load bearing applications. It also prevents flow of heat from inside of the chimney flue towards floor beam.
More over Syndanio NA blocks are also used to cover chimney flue surfaces.
