The DuraVent DuraChimney II 16" Roof Radiation Shield is a premium factory-built chimney system component designed to enhance safety where the chimney passes through roof assemblies. Ideal for wood-burning fireplaces, stoves, and solid-fuel venting systems, this roof radiation shield 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 chimney applications. It provides critical protection in roof penetration areas while maintaining proper chimney system clearance and performance.

Engineered for high-performance safety, the DuraChimney II roof radiation shield operates within a double-wall, air-cooled chimney system that keeps exterior surfaces cooler while supporting a strong, efficient internal draft. The system allows for thermal expansion both radially and lengthwise under extreme heat conditions, ensuring long-term durability and 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 fire safety and protection.
