SM250 twin wall flue

A double skin insulated chimney system allows you to quickly, easily and safely create a chimney virtually anywhere in the house, with the minimum of disturbance. It can come within 50mm of combustible material and, with clip together sections, three different bend angles and pre-made flashings it is very straightforward to install.

We can still supply SM250 flue - however SM250 is so similar to Selkirk STC twin wall flue that we cannot justify the price difference. We now concentrate on Selkirk STC flue - click for further details.

If you tell us some basic measurements of where you would like to install a stove, we can work out all the different components you would need and come back to you with the total price for the system, delivered to your door. We are then on the end of a phone if your installer has any questions. Please see our flue design page for more details.
