300mm (12") twin wall

Twin Wall Insulated Flue System - Commercial & Domestic Applications

This system is fully insulated using 30mm condensed Rockwool between the inner and outer wall.  Distance to combustibles is 60mm (therefore, make sure that you keep a distance of 60mm from the outside of the flue to any combustible material e.g. wood, plaster board).  

N.B. This Twin wall flue system can be used in condensing applications.  Please order and fit a seal/joint with each component.

Please note:  Diameter sizes are the internal flue size.
