Dura Vent DuraChimney ll 16DCA-IS Attic Insulation Shield
The DuraVent DuraChimney II 16" Attic Insulation Shield is a premium factory-built chimney system accessory designed to enhance safety and thermal protection where the chimney passes through attic spaces. Ideal for wood-burning fireplaces, stoves, and solid-fuel venting systems, this insulation shield is part of the trusted DuraChimney II double-wall chimney system, offering a lightweight, unitized design that eliminates field assembly of pipe sections for faster, more efficient installation in residential and commercial applications. It ensures proper clearances while maintaining safe chimney operation through combustible attic areas.
Engineered for high-performance chimney safety, the DuraChimney II attic insulation shield works within a double-wall, air-cooled chimney system that keeps exterior surfaces cooler while maintaining strong internal draft efficiency. The system accommodates radial and lengthwise thermal expansion under extreme heat conditions, ensuring long-term durability and 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 fire protection and insulation performance.
