New, economical, twist-lock, twin wall flue system: Sflue

11 December 2015

With the heating season firmly upon us and the popularity of wood-burning stoves ever on the increase, home-owners and installers alike are always looking for a healthy balance of quality and affordability. That’s exactly what you can expect from Sflue.

The most important factors in deciding on a stove and twin wall flue system must always be safety, followed by performance, life expectancy and ease of installation/maintenance. These are all excellent reasons to choose a UK manufactured flue system from a market leading company with over 40 years of experience.

Sflue from SFL Flues and Chimneys follows in the footsteps of time honoured brands such as NOVA® and EUROPA. Designed as an entry-level twin wall flue system specifically for wood-burning and multi-fuel stoves, Sflue is available in four internal diameters from 127mm (5”) to 203mm (8”) and features a multi-barb, twist-lock coupling system for ease of installation and high mechanical strength. The range of components is specific to stove installation, complete with an aesthetically pleasing straight adaptor for direct mounting. Each component is supplied with locking bands as standard.

Sflue features a fully welded 316L corrosion resistant liner, 25mm of high-performance rockwool insulation at a factory controlled density of 250kg/m³ (enabling the flue to be installed with a minimum 50mm to combustible surfaces), and an elegantly polished, fully welded stainless steel outer skin.

The construction provides a high thermal resistance which ensures rapid stabilisation of the flue gas temperature and draught, whilst maintaining relatively low temperature on the external surface of the chimney. Sflue is designed for internal and external installation, and is suitable for negative pressure applications.

SFL has worked with customers and installers to design a range of new components suitable for the modern stove market, including an adjustable wall sleeve and a range of specific adaptors for common connecting pipes. Elbows and 135° tees feature an un-barbed coupler to facilitate full rotational adjustment and a screw-toggle locking band for extra stability during installation.

Sflue has been developed to provide a high quality chimney with a fine pedigree at an attractive price. It is CE marked, HETAS listed, comes with a 10 year warranty, and is completely British-made.

SFL also produces a complementary brand called SIGMA, which is a stainless steel single wall connecting flue.
