Darco Chimney Cowls

Chimney cowls are designed to stabilize and increase chimney draft in ventilation and smoke ducts. Chimney cowls are mounted on the top of chimney ducts. Their purpose is to prevent downwind, rain, ice build-up and bird nesting, but most of all they are designed to generate a chimney draft using the force of the wind. Chimney cowls are available in two versions, one, with a flat openable square base, is suitable for flat chimneys, while the openable inlet pipe version is for installation on existing chimney liners.
