Types of Selkirk flue

Selkirk twin wall flue

Selkirk STC twin wall flue, selkirk flue UK Selkirk STC - twin wall chimney. A twin wall insulated flue with welded seams and an inner layer made of 316 grade stainless steel, able to withstand corrosive flue gases given off by wood burning and multi fuel stoves. Selkirk STC flue can be used internally or externally as the outer layer is also made of stainless steel. The 25mm of insulation between the layers of Selkirk flue keeps the outside of the flue cool as well as ensuring that the flue gases remain warm, thus reducing the tar deposits that can cause chimney fires.

Selkirk twin wall flue is the only flue system that has got around the problem of ventilated floor penetration components. Ventilated floor penentration components can allow the transmission of smoke into the room above. We see this as a big problem as most deaths in a house fire are caused by smoke inhalation. A new innovative ventilation system that has been fully tested and approved to EN1856 and allows the use of non ventilated floor penetration components when using Selkirk STC twin wall flue run through a bedroom or other storage space. No other type of twin wall flue in the UK allows this. Click here for a broader discussion of the topic.

Selkirk flue may pass within 50mm of combustible materials making it very easy to install in existing houses. A full range of support components, bends and tees are also available.

Working lengths: 1181mm, 876mm, 572mm, 419mm, 276mm, and 114mm.
