Single-skin flue systems

Single-skin flue systems are what most people think of when it comes to the construction of commercial and industrial ducting, flue systems and chimneys, as they carry combustion gases away from boilers in CHP units.

Their stainless steel construction is ideal for both internal and external usage within a commercial property. If they are maintained within the manufacturer’s recommended guidelines, they can function to optimum levels of performance for years.

Single-skin systems are designed for use where:

  • A four-hour fire rating is specified
  • A positive-pressure high-temperature exhaust or duct system is specified
  • A watertight flue system is specified

Application examples include:

  • Condensing boilers
  • CHP systems
  • Fan-assisted flue systems
  • Kitchen extraction systems
  • Smoke extraction systems
  • Flue dilution

The complete range of A1 Flue Systems’ single-skin flue systems has been successfully tested in accordance with B5476 Part 20 for stability and integrity during a four-hour fire test.

All our single-skin flue systems are have been CE Marked in accordance with British Standard (BS) 1856.
