Chimney Cowls

Chimney cowls play an essential role in preventing downdraft and keeping your home safe. If you use a wood-burning stove or fireplace to heat your room, a chimney cowl will help to stop smoke from coming back down the chimney.

As well as traditional chimney pot covers for use with solid fuel fires, you can also find specialist alternatives suitable for gas and oil systems too – at Toolstation, we stock an extensive range featuring everything from spinning chimney cowls to mesh flue guards.

What are chimney cowls used for?

It’s not just downdrafts that a chimney cowl can prevent. It can also prevent rainwater, leaves or debris from entering, and some designs come with a bird guard too – this helps to prevent birds getting into the chimney and nesting.

You’ll find various configurations and materials including stainless steel and aluminium chimney toppers, and a choice of colours – terracotta blends in with many rooftops, making it a particularly popular option.

Chimney Caps

While a chimney topper or cowl can minimise downdrafts, sometimes you’ll need to seal off a disused chimney completely. That’s where a chimney cap comes in handy – it helps to protect the system during the winter months while reducing heat loss, yet allows essential ventilation.
