Where the classic elemental chimney reaches its limits, selection of a FSB system makes sense. The FSB is a free-standing, insulated steel chimney with a inner static supporting flue gas liner.
The outer cladding is stainless steel or aluminium depending on the need. The outer surface can be shinny, brushed or matt as per the requirement of the customer making the chimney look elegant and architecturally appealing. This system is light weight, usually affixed with one or more brackets to a building and suitable up to temperature of 400 degrees.
