You may require a Cowl/Bird Guard if you would like to prevent rain, birds, squirrels from entering the flue. We can supply a wide variety of Cowls for our customers preference.
The fitting of a cowl is very beneficial especially for fireplaces or stoves that are in use.
They mainly prevent birds from nesting and water from entering the chimney which could cause dampness within the chimney.
You can also help prevent anti downdraught by having an anti-downdraught cowl fitted, or even a spinning cowl to help increase the up draught.
