Case Study 2 - Inglenook Chimney Relines
We treat any chimney with a minimum internal flue size of over 350 mm x 350mm as an ‘inglenook chimney’ . The large void originally constructed to move large amounts of smoke from a large fire needs a different approach from the ‘standard reline’. There are many variations in sizes of inglenook chimneys and in some cases we can climb a ladder inside the flue.
Each inglenook chimney reline has its own site requirements; to gain safe access and to fix and support the liner without detriment to the ancient structure is top of the list. As backfilling the large void around the new flue with vermiculite insulating backfill is unpractical, a better way to insulate is to sleeve the liner with a suitable insulating wrap. The 500 year old inglenook fireplace (above left) is a weak structure at the heart of the property. The original clay bricks are crumbling through centuries of abuse.
Spreading the weight of the new liner is very important. Generally a liner in an inglenook chimney will need at least 3 points of support. The weight of the liner is increased by the insulating wrap and soot build up in the future, simply hanging the liner from an old chimney pot is not good enough in any situation. In some cases a better approach would be to use a rigid chimney system based upon the old clay structure being able to take the additional weight and support components. The restoration of an old Essex inglenook chimney is a challenging but very satisfying part of our work.
