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 manufactuer an insulated roof penetration kit to avoid a cold bridge when penetrating a roof. You can find out more on this topic here
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, 267mm, and 114mm.
Given a few details we will design your Selkirk flue system for free - visit our Flue design page for more details.
125mm systems - building regulations advise a mimimum flue size of 150mm and HETAS installers may not fit or connect to a 125mm system. Read more about 125mm flue systems here.
Extra Selkirk flue information:
Flashings for twin wall insulated flue systems
Please be aware that we have three main types of flashings available for Selkirk flue systems going through tiled or slated roofs.
The first and most popular in the UK, is Lead Flashing.
A high quality code four lead, machine cut and welded specifically for Selkirk STC flue systems (as priced below), favoured by installers and developers as not only are they easy to use, but match the rest of the lead that is quite common on our properties.
Also, we have Seldek Nu lead and Alu Based flashings; suitable for just about any manufacturer of twin wall flue pipe or cylindrical pipe leaving a roof surface.
A large square based plate of lead, coated with Acrylead, which takes the form of any profiled roof tile, with an EPDM cone. This can withstand temperatures from -50 to 115 degrees, and seals against the flue pipe as it penetrates the flashing. This is also available with an Aluminium base, ideal for our flat slate roofs.
The EPDM cones are carefully cut to size on site, to suit the very diameter flue or pipe you are working with.

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.
