DuraVent DuraChimney II 12" Storm Collar
The DuraVent DuraChimney II 12" Storm Collar is a high-quality factory-built chimney system accessory designed to provide superior weather protection for chimney roof penetrations. Ideal for wood-burning fireplaces, stoves, and solid-fuel venting systems, this storm collar is part of the trusted DuraChimney II double-wall chimney system, offering a lightweight, unitized design that eliminates field assembly for faster, more efficient installation in residential and commercial applications. It delivers a secure sealing solution that helps protect the chimney system from rain and moisture intrusion.

The system allows for thermal expansion both radially and lengthwise under high heat conditions, ensuring long-term structural reliability. 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 dependable, code-compliant chimney protection and long-lasting weather sealing performance.
