A flue liner creates a smooth surface in the chimney which facilitates the escape of potentially dangerous gases, as well as providing a powerful form of insulation. Well-built houses used to be lined with mortar or clay tiles; yet, many chimneys have never been lined and have the potential to cause significant problems to the health of a home’s inhabitants. An effective lining in a very flue will assist you to protect the structure, whilst ensuring that dangerous gases and smoke pass harmlessly to the atmosphere.

Flue liner is susceptible to degradation with time in exactly the same way as mortar and bricks are. Cracks will inevitably develop in lining over time and permit moisture and combustion gases to enter the brickwork. This process can attack the structural integrity of a chimney over a period of time and may lead to problems with ventilation or cause serious harm to the construction. The kind of lining a chimney needs will depend on the kinds of fire being burned in the house. A multi fuel flue liner will be required by homeowners with wood – burning stoves or open fires.

Clay tile lining continues to be used widely; nevertheless, many homeowners are now selecting for stainless steel flue liner insulating material that often includes all of the equipment required for installation. This can be a simple and comparatively inexpensive alternative to clay tiles and cast – in – place lining but will incur the extra expense of insulating jackets and wraps.

Corrosion is usually the outcomes of acidic condensates, which in turn hints at extra troubles with the flue, but the immediate dilemma is leakage.

If a chimney is not effectively sealed, due to either deterioration of the materials or a physical breach, then it can leak smoke (containing potentially lethal carbon monoxide) into rooms in the residence. Needless to say, most chimney surveys do verify for leaks.

Actual breaches of the chimney are most often brought on by later building operate, normally extensions and loft conversions. It is not uncommon to discover joists resting on the flue brickwork and as a result causing both an obstruction and a leak at the very same time.
