Dunbrik Chimney Block System

The Dunbrik chimney block system comprises an outer concrete casing block with mortared joints with an inner concrete 200mm id flue liner and an insulation wrap between.

The flue liners are jointed using a fire resistant mortar to a tongue and socket detail. A precast chamber with integral gather unit allows a range of appliances to be used along with any domestic fuel.
