Clay, metal, or concrete extensions fitted on top of a chimney stack to improve the updraft and direct smoke safely away from the roof.

​

• Common in traditional and period properties.

• Come in various shapes and sizes to suit different fireplaces or stoves.

• Can help improve chimney draft performance and reduce downdraughts

​

Why it matters:

Properly sized and fitted chimney pots help your flue ventilate more efficiently and maintain proper airflow.

A device fitted to the top of a chimney pot or flue terminal to prevent:

​

• Downdraughts (wind blowing smoke back into your room)

• Rainwater ingress

• Animal or debris entry

• Some cowls also help increase draft for better appliance performance

• Made from stainless steel, aluminium, or galvanized steel

• Types include:

  • Anti-downdraught cowls

  • Rotating cowls (spin with wind to create suction)

  • H-Style cowls (for extreme wind exposure)

​

Why it matters:
Fitting a cowl can significantly reduce smoke blowback, moisture damage, and flue blockages.

A type of cowl or cap that includes a mesh or grille to prevent birds (especially jackdaws) from nesting in the chimney.

 

• Essential in rural or wooded areas.

• Can also stop leaves, debris, and small animals from getting inside.

Why it matters:
Bird nests are one of the most common causes of chimney blockages and fire risk — a bird guard prevents this safely and humanely.
