A chimney liner is obligatory if you are installing a woodburning stove, gas fire or open fire in a new build property to comply with Document J of current building regulations.
Older chimneys will often require a modern lining solution for the following reasons:
The flue may have lost integrity and can leak smoke into rooms .
Condensation or tar can seep through chimney walls causing staining.
Bad draw: Lining with insulation included can improve the operation of the appliance and flue – particularly important when the chimney is situated on an external wall.
Poor up-draught: Defective flue systems may be eroded and rough. This will cause frictional resistance to the flow of the gases resulting in poor up-draught.
Large flue: Some appliance manufacturers specify smaller flues for efficient operation.
A CCTV inspection carried out by a chimney professional will clearly show the condition of your flue.
