Twin wall flue systems

London Twin Wall Flue installation


A twin wall flue system can be fitted through your building or externally. At M Dole chimneys we design all our own twin wall systems. We only use class one stainless steel, all twin wall systems are passed by


  • Heatas
  • Building control
  • Gas safe


These flues are used for fires without an existing chimney. We fit them for use for:

  • Stoves
  • External flues
  • Internal flues
  • Gas boilers
  • Open fires


Please note twin wall flue systems must be at least 4.5 metres high, 50mm from all
combustible materials and 600mm clear of your ridge.
