Chimney crown vs. chimney cap: what each one does
Learn the differences between a chimney crown and a chimney cap, and how they protect your chimney.
What is a Chimney Crown?
The chimney crown is the top surface of your chimney and is designed to protect the chimney structure from weather elements. It directs water away from the chimney to prevent brick and mortar degradation.
Typically made of concrete or metal, a well-built crown helps keep rain, snow, and debris from entering the chimney, extending its lifespan and efficiency by preventing water damage.
What is a Chimney Cap?
A chimney cap sits directly on top of the chimney crown and serves multiple purposes. It prevents rain, animals, and debris from entering the chimney. Most caps include a mesh that keeps the critters out while allowing smoke to escape.
Aside from blocking unwanted materials, a chimney cap also reduces downdrafts and can help prevent sparks or embers from escaping, which can ignite nearby combustibles. It acts as a barrier, enhancing safety.
Why Both are Important
Having both a chimney crown and cap installed ensures comprehensive protection for your chimney system. They work together to keep your chimney dry and safe from external threats.
Together, they prevent structural damage and block unwanted animal access, improving the overall efficiency and safety of your fireplace and chimney system for years to come.
