Chimney crown vs. chimney cap: what each one does
Learn the differences between a chimney crown and a chimney cap, including their purposes and benefits.
Understanding the Chimney Crown
The chimney crown is a concrete slab that sits on top of the chimney, sealing and protecting the bricks and mortar from weather elements.
A well-constructed crown slopes away from the flue to direct water off the chimney to prevent damage. It acts as a crucial barrier against water penetration.
Role of the Chimney Cap
A chimney cap is a metal covering that sits on top of the chimney flue, designed to prevent rain, debris, and animals from entering the chimney.
Chimney caps also have mesh siding to allow smoke to exit while keeping intruders out, and they assist in reducing downdrafts.
Benefits of Both
Together, the chimney crown and cap work to protect the chimney structure, ensure proper draft, and maintain efficiency and safety.
Routine inspections and maintenance of both components can preserve your chimney’s longevity and prevent costly repairs.
