FSB
Free-standing, insulated and cladded steel chimney with a inner static supporting flue gas line.
When the classic element chimney reaches its limits, the single-duct FSB can be a sensible alternative.
For the welded and insulated flue gas flue, which also serves as a static load-bearing element, pressures of over 1.02psi and projections of over 23ft are no problem.
The FSB can be found between the element chimney and the classic free-standing steel chimney FSA and is usually attached to the building with one or more brackets.
Due to the cladding with elements, this variant looks just as elegant and architecturally appealing as an element chimney.
