More Info


The Adjustable Wall Sleeve is used when the flue system passes through an outside wall, to:

  • protect the chimney
  • stop escaping flue gasses

The gap between the flue and the Wall Sleeve is filled with rockwool.

This Wall Sleeve is pre-cut at 45º and is adjustable so it can be extended to the right size.

NOTE – The 150 diameter referred to in twin wall chimneys is the internal diameter - the external diameter is 200mm and is not used to describe the part.
