Liners For Inglenook Chimney's
Inglenook chimneys, usually found in properties over 300 years old, were designed to cope with masses of heat and smoke produced by large open fires used for heating, cooking and in some cases for the occupiers' trade (baker, blacksmith etc.). The oversized flues do cause problems with modern living as, even when not in use, the chimney rapidly pulls air from your house. This may be fine in summer, but in winter an inglenook can remove all of the heat produced by central heating in a room every 10 minutes. The perfect answer is to add a smaller, more controllable fire that needs a greatly reduced flue size. We find that stainless steel flexible or rigid flue systems are best to use in inglenooks, as the method of installation allows the least disturbance to the ancient structure.
The main aim of insulating a flue is to ensure the unburned gasses (smoke) from an appliance reach outside without cooling and condensing on the way, creating a sticky tar build up. With inglenook chimneys it is usually not practical to back-fill around the new flue using vermiculite, therefore an insulating wrap is used.
