Reasons for lining and/or insulating a chimney

When using a wood burning or multi-fuel stove

  • Insulating your chimney liner reduces tar and soot deposits thereby reducing the risk of a chimney fire.
  • Lining your chimney creates a continuous smooth chimney with less surfaces for tar or soot to condense onto. Tar that does form can flow directly back to the stove to re-combust as opposed to building up in the rough crevices of a masonry chimney.
  • Insulating your chimney liner increases the temperature of the flue gases, which in turn will tend to improve the draw of a chimney since warm air rises.
  • Lining your chimney will cure problems of smoke leaking out through cracks in a masonry chimney.
  • Lining your chimney will stop new tar from leaking out through cracks in the chimney or onto your stove.
  • If your chimney is very large then lining your chimney for use with a stove can be a safer option as flue gases in a large chimney cool very quickly resulting in a high level of condensates which are hard to remove when sweeping.

Containing the flue gases in a pipe of consistent diameter maintains the flow and velocity of the gases in the system - i.e. the flue gases will travel faster. This will reduce deposits (as the gases spend less time in the chimney and cool less) and will also improve the draw.
