Cowls & Terminals 

We offer a wide range of cowls and terminals to cover the chimney pot of your installation. The cowls that can be seen on this part of the website do not hold the flue liner in place, and are used as a method to stop birds nesting and debris falling down your stack, without it holding the liner in place. 


If you need to use one of our anti-downdraft cowls, they too strap/bolt around the pot, not the liner. If you use an anti-downdraft cowl with the twin wall system, you would need to purchase a top stub in the corresponding size of twin wall that you plan to use.
