Chimney cowls offer style and elegance for the perfect finishing touch to any chimney. The metal-based chimney cowl comes in an H shape and gets its name as its shape resembles the cowl worn by monks in olden times. The cowl and the chimney pot are used for ventilation of solid fuel systems and help draw smoke up the chimney, efficiently increases draft, and prevents backflow.
These cowls are made typically out of galvanized iron and prevent the smoke from going back into the room below when winds are strong. There are different heights and colors to choose from and a wide variety of cowls can be fitted. In order to select a chimney cowl that will function properly, it is important to consider the chimney pot. The cowls also prevent birds and squirrels from nesting in the chimney, prevent rainwater seepage, and can also arrest sparks when used with a metal mesh.
