Flue pipes
A1 Flue Systems is the UK market leader in the design, manufacture and installation of commercial and industrial chimney, flue and exhaust systems: what our industry simply refers to as flue pipes.
Broadly speaking, flue pipes fall into two main categories: single-skin flue systems and twin-wall flue systems.
Single-skin flue systems - these stainless steel systems are ideal for both internal and external usage within a commercial property to carry combustion gases away from boilers in CHP units. All our single-skin flue systems have been successfully tested in accordance with B5476 Part 20 for stability and integrity during a four-hour fire test.
Twin-wall flue systems - these are double lined and contain insulation between the twin walls to reduce the transfer of heat from the interior of the flue to the exterior. As with the single-skin flues, all our twin-wall flue systems are tested in accordance with B5476 Part 20 for stability and integrity during a four-hour fire test.
All our single-skin flue systems and twin-wall flue systems have been CE Marked in accordance with British Standard (BS) 1856.
