DuraChimney II Chase Top Flashings are designed to enclose the top of a chimney chase while allowing essential ventilation airflow into the chase structure. Built for secure, code-compliant installations, each flashing includes spacer clips to ensure proper clearance and airflow around the chimney pipe. Ideal for use with custom or site-built chases, this component helps maintain the performance and safety of your DuraChimney II system.
Additional Durachimney II Info:
DuraChimney II offers a high-performance, factory-built alternative to traditional masonry chimneys. Its unitized, lightweight construction eliminates the need for field assembly of pipe sections, making installation faster and more efficient. Engineered with a double-wall, air-cooled design, DuraChimney II stays cool on the outside while maintaining a strong, hot draft on the inside. This fire-safe system is built to protect both the chimney and the structure. It allows for thermal expansion in all directions under high heat and is tested to UL 103 standards—approved for continuous operation at 1000°F, one hour at 1400°F, and ten minutes at 1700°F.
