8" SFLUE Stainless Steel Insulated Twin Wall

8" Stainless Steel SFLUE Twin Wall

A quaility twin wall flue system designed and built in Britain to meet requirements for multi-fuel appliances operating under negative or non-condensing conditions. The fully welded construction, combined with a high performance insulating medium, provides the optimum level of performance for both DEFRA approved and the latest EcoDesign high-efficiency stoves, in addition to both modern and traditional appliances.

Twist-Lock Jointing System

Sflue utilises an eight-barb twist lock jointing system to secure each joint. The components are secured by engaging the barbs with a firm twist of each section, and then finished with a locking band. The joint design facilitates a maximum unsupported height above the last support of up to 1.5 metres. A locking band is provided with all female ended couplers.

Insulation Properties

The product utilises a high performance mineral wool, which is auger injected into a 25mm annulus between the inner and the outer. A mean insulation density of 250kg/m3 offers rapid stabilisation of draught and excellent thermal performance. The insulation properties achieve a 50mm distance to combustibles and a 2 hour fire rating.
