Sflue is a prefabricated, factory made twin-wall insulated stainless steel system chimney. The fully welded construction, combined with a high performance / high density insulating medium, provides the optimum level of performance required for modern-day solid fuel appliances such as DEFRA approved high-efficiency wood-burners alongside traditional stove installations.
The product utilises a high performance mineral wool which is auger injected into a 25mm annulus between the inner and outer to a mean density of 250kg/m3, offering rapid stabilisation of draught and excellent thermal performance.
Sflue utilises an eight-barb twist lock jointing system to secure each joint, a locking band must then be used at each joint.
Sflue is available in 2 internal flue diameters ranging from 127mm - 152mm and is suitable for solid fuel applications operating under negative draught / dry conditions or where the maximum positive pressure will not exceed 40Pa as designated by N1, at a maximum flue gas temperature of 450°C.
Sflue is available in 4 different lengths - 120mm, 300mm, 500mm, and 1000mm. All sizes and lengths are available in Silver or Satin Black finish.
