Selkirk flue
Types of Selkirk flue
Selkirk twin wall flue
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 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. Other twin wall flue manufacturers are now starting to see the sense of this and move to solid compontents. 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.

POWDER COATING SERVICE
BLACK: We can supply Selkirk STC flue pipe in a powder coated black finish. This gives an amazingly good finish which is also very hardwearing and suitable for external use. Just let us know which sections you would like powder coated. The black powder coated finish comes out very black indeed and is a slightly glossy finish as you can see in the picture. Please bear in mind that if you want a match for your stove then you are better off spraying the flue with high temp spray (which we can of course supply).
Black powder coated Selkirk STC flue costs 25% extra.
COLOURSWe can supply your flue pipe in custom colours. You need to supply us with the RAL number of your chosen colour, there is a 14 day lead time. Custom coloured finishes are 35% extra.
