Chimney crown vs. chimney cap: what each one does
Learn the differences between chimney crowns and caps and their roles in protecting your chimney.
Understanding the Chimney Crown
The chimney crown is a concrete or mortar surface that covers the top of the chimney, sealing the area around the flue. It acts as a protective shield against weather elements like rain and snow.
A well-constructed chimney crown slopes downward to direct water away from the flue, preventing water intrusion and subsequent damage to the masonry.
The Function of a Chimney Cap
A chimney cap is a metal covering installed over the top of the chimney. It serves to keep rain, debris, and animals from entering the chimney.
Apart from offering protection from the elements, a chimney cap also prevents downdrafts from happening, keeping smoke and odors from re-entering your home.
Which One Do You Need?
Both the chimney crown and cap have distinct roles in chimney protection. While the crown protects the structure, the cap guards against external intrusions.
Ensuring both are in good condition is crucial for preventing moisture damage and maintaining efficient chimney operation. Regular inspections can help spot any wear and ensure both elements are functioning correctly.
