S-Flue Twin Wall Flue Chimney System

S-Flue has been specifically designed to meet the requirements for multi-fuel appliances that operate under negative or neutral draught conditions. Under no circumstances should S-Flue be used on appliances that generate high levels of condensation or positive pressure within the chimney system. For such systems our NOVA® product should be used.

    Twin-wall insulated stainless steel system chimney

    S-Flue 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.

  • Features

    Twist-Lock Fitting

    S-Flue utilises an eight-barb quick lock jointing system to secure each joint. The components are secured by locating the barbs with a twist of each section. A locking band must then be used at each joint. The joint design facilitates a maximum unsupported height above the last support of up to 1.5 metres, subject to the design considerations detailed within the Installation Instructions and on page 14 of this brochure.

  • Features

    Application flexibility

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