Cowls have been fitted to chimneys through the ages and are designed to overcome traditional as well as modern everyday problems. They may be fitted for a number of reasons including to:
- Overcome smokey chimneys and smokey rooms
- Reduce draughts in rooms with open chimneys
- Deter birds or vermin from entering or nesting
- Prevent entry of rain water
- Cap off redundant chimneys
- Ensure safer and more efficient ventilation

Left uncapped disused chimneys are prone to a number of serious problems arising from exposure to the elements and blockage by nesting birds. Fitting a cap provides instant protection against these problems, potentially saving hundreds of pounds on costly repairs.
Below are just a few examples of the many dozens of chimney terminals that are on the market. It is vital that the correct terminal is fitted. An inappropriate terminal may cause the chimney to operate incorrectly and inefficiently which may not only cost you financially but can also lead to poisonous fumes from your fire not being expelled and putting your family at risk of carbon monoxide poisoning.
Bristle Chimney Sweeping will give you advice regarding chimney terminals.

If you have one of these fitted to a live flue you should stop using it immediately and seek advice.
