The DuraVent DuraChimney II 14" Chimney Cap is a high-performance factory-built chimney system accessory designed to protect and optimize the top of DuraChimney II double-wall chimney installations. Ideal for wood-burning fireplaces, stoves, and solid-fuel venting systems, this chimney cap provides a lightweight, unitized design that eliminates field assembly for faster installation. It delivers a durable, weather-resistant finishing solution that enhances the overall safety and efficiency of residential and commercial chimney systems.

Engineered for maximum performance and durability, the DuraChimney II chimney cap works within a double-wall, air-cooled chimney system that maintains cooler exterior surfaces while ensuring a strong internal draft for efficient venting. The system allows for thermal expansion both radially and lengthwise under high-temperature conditions, ensuring long-term structural integrity. UL 103 listed, DuraChimney II is tested for continuous operation at 1000°F, one hour at 1400°F, and ten minutes at 1700°F, delivering reliable, code-compliant chimney protection and airflow performance.
