Chimney Cowls

Q: What is a chimney cowl?

Chimney cowls or pot caps are fitted to the top of chimneys to solve a wide range of common issues, while also improving the performance of the chimney. They can be made from a range of materials, and include mesh structures, plastic caps and more complex metal structures.

Q: Why use a chimney cowl?

Chimney cowls have been designed to specifically combat issues with chimneys to help create a clear, efficient and safe fire and flue system.

Q: Do chimney cowls prevent water ingress?

Yes, the installation of a chimney cowl prevents the ingress of water into the flue system. In some circumstances, flue systems are sensitive to moisture and water, and long-term issues can arise, such as rust and structural damage.

Q: Can chimney cowls eliminate downdraught?

A major benefit of installing a chimney cowl is to reduce or prevent downdraught. A chimney cowl will help to reduce or eliminate downdraught by stabilising airflow and preventing exterior draughts and wind from forcing smoke back down the chimney.

Q: Do chimney cowls increase draw?

Chimney cowls are incredibly useful when looking to improve the draw of the fire. A chimney cowl improves the efficiency of the fire, the burn rate and the speed at which smoke and hot air are drawn up through and out the chimney. It is important to only use a chimney cowl that is specifically designed to increase draw on poorly performing fires, as if used on an already well-performing fire it can cause issues including overfiring.

Q: What size chimney cowl is best?

Chimney cowls are available in a variety of sizes, so it is important to get the correct size for your chimney. Standard sizes range from 100mm to 300mm – this is the internal diameter measurement.

Q: How do you fit a chimney cowl?

Fitting a chimney cowl is incredibly simple. The cowl simply needs to be strapped, bolted of fitted with a sleeve over the chimney.
